In my case, the bits that come with mongoose (<code>npm install mongoose</code>) have a working version of the <code>mongodb</code> package in its <code>node_modules</code> folder.

The following steps saved me the work of troubleshooting the issue:

<ul>
<li><code>npm install mongoose</code></li>
<li>copy <code>node_modules\mongoose\node_modules\mongodb</code> to my root <code>node_modules</code> folder (overwriting any version that came with <code>npm install mongodb</code>)</li>
<li>ignore the <code>Failed to load c++ bson extension...</code> error (or change the code to be silent on the issue)</li>
</ul>

If you are using windows 8.1, you might want to make sure that you are installing your npm modules with the correct visual studio compiler.

I have Visual Studio 2012 installed, this command works for me.
(after deleting node_modules dir)

npm install --msvs_version=2012

For some reason, node-gyp is trying to use the incorrect version of Visual Studio compiler. I also noticed that the "npm install" command was printing out a warnings about not node-gyp dependencies when installing the mongodb and mongoose modules.

After using the correct msvs_version, the npm install warnings went away as well as the console warning when running my nodejs app.

You might also want to make sure that you have the correct Python 2.7.X version installed and not Python 3.0.X.

You will also need to make sure that python is in your env path.

Reinstall node and python with x32 versions. 
I spent many time with this error (Failed to load c++ bson extension) and finally, when I installed module <code>node-gyp</code> (for build native addons) and even installed windows SDK with visual studio - nodejs didn't recognize assembled module bson.node as module. After reinstall the problem is gone.

Again, What means this error?

Actually, it's even not error. You still can use mongoose. But in this case, instead of fast native realization of bson module, you got js-realization, which slower. I saw many tips like: "edit path deep inside node_modules..." - which totaly useless because it's not solve the problem but just turned off the error messages.

The problem is when you install mongoose via npm it assumes you have python installed on your windows and tries to build required libraries. Since you do not have python it skips building phase with a warning. But when you start your application, required modules are not there so you get this error. 

In order to do things right first install python (version 2.7) on your computer from: <a href="https://www.python.org/downloads/">https://www.python.org/downloads/</a> or if u have installed chockolatey just type <code>choco install python2</code>.

Then make sure your python variable is set. You can set it on command prompt like:

<pre><code>SET python=D:\Python27\python.exe
</code></pre>

(Of course you should change the path according to your location of python)
Then install node-gyp:

<pre><code>npm install -g node-gyp
</code></pre>

Now you can reinstall mongoose or whatever module causing the problem:

<pre><code>npm install mongoose
</code></pre>

You will see some yellow lines instead of red ones this time but the error will be gone.

So, i have the same problem and it happens then the specified mongoDB URL doesn't exist. So, to fix this you need to go "..\server\config\environment" folder and edit in "development.js" file the link to mongoDB.

Example:

<pre><code>// Development specific configuration
// ==================================
module.exports = {
 // MongoDB connection options
 mongo: {
 uri: 'mongodb://localhost/test2-dev'
 },

 seedDB: true
};
</code></pre>

So, change this "uri: 'mongodb://localhost/test2-dev'" to some real path to your mongoDB database.

You should never change files in NODE_MODULES library folder.

Those files are result of <code>npm install</code> command.

Basicaly, I think for Windows users - right way is use VM. It's what I'm doing when I work from home.

All you need:

<code>for CentOS: yum install gcc gcc-c++ make openssl-devel</code>

<code>for Debian/Ubuntu: apt-get install build-essential</code>

and then <code>npm install</code> or, if you have already done it - <code>npm update</code>

The marked answer is completely wrong. All that does is hide the console log statement and does nothing whatsoever do address the actually issue. You can also close your eyes and it will achieve the same result.

The issue is caused by node-gyp and only that. Its purpose is to compile native extensions for certain modules such as bson.

If it fails to do so then the code will fallback to the JS version and kindly tell you so through the informative message:

<pre><code>Failed to load c++ bson extension, using pure JS version
</code></pre>

I assume the question is really about how to compile the native C++ extension rather that just not seeing the message so let's address that.

In order for node-gyp to work your node-gyp must be up to date with your node and C++ compiler (that will differ based on your OS). Just as important your module must also be up to date.

First uninstall and reinstall node-gyp

<pre><code>npm un node-gyp -g;npm i node-gyp -g
</code></pre>

Now you will need to fully uninstall and reinstall any node module in your app (that includes modules installed by requirements as well) that have bson. That should take care of the error. You can search for 'Release/bson' and find the culprits.

<pre><code>find node_modules/ -type 'f' -exec grep -H 'Release/bson' {} \;
</code></pre>

And then uninstall and reinstall these modules.

Easier is to just redo the entire <code>node_modules</code> folder:

<pre><code> rm -rf node_modules
 npm cache clear
 npm i
</code></pre>

If you still experience issues then either 1) your module is out of date - check issue tracker in their repo or 2) you have a potential conflict - sometimes we may have a local node-gyp for example. You can run <code>node-gyp</code> by itself and verify versions.

This worked for me. Search in your workspace for the text:

<pre><code>"../build/Release/bson"
</code></pre>

You will probably find it inside the mongose and monk modules.

Then replace each:

<pre><code>bson = require('../build/Release/bson');
</code></pre>

with:

<pre><code>bson = require('bson');
</code></pre>

that's all!

<h2>Short answer</h2>
Install the latest version of mongodb.
<h2>A little longer answer</h2>
Make sure your package.json is using the latest version of mongodb,
then remove node_modules/mongodb and do npm install again.
If you didn't use mongodb as a direct dependency, try to find which package is using mongdb. I used:
<pre><code>find . -type f -name package.json | xargs grep mongodb
...
./sails-mongo/package.json: &quot;mongodb&quot;: &quot;1.4.26&quot;,
...
</code></pre>
So I updated ./sails-mongo/package.json to:
<pre><code>&quot;mongodb&quot;: &quot;2.1.7&quot;,
</code></pre>
Then remove node_modules/mongodb and do npm install again. Seems fine now.
<h2>Even longer answer</h2>
I don't like the current suggested way of using
<pre><code>require('../browser_build/bson')
</code></pre>
Since looking at ../browser_build/bson.js, a 4k+ lines file, which seem also a &quot;non-native&quot; implementation. So although it won't spit out any complains, it is still &quot;using pure JS version&quot;, which means slower performance.
Looking at <a href="https://github.com/mongodb/js-bson/issues/145" rel="noreferrer">https://github.com/mongodb/js-bson/issues/145</a> and <a href="https://github.com/mongodb/js-bson/issues/165" rel="noreferrer">https://github.com/mongodb/js-bson/issues/165</a>, it seems like the issue was caused by:
<blockquote>
antoniofruci commented on Sep 15, 2015
I just found out that c++ code has been moved out 6 months ago and it is now an optional dependency: bson-ext. Indeed, if you install latest version no error occurs.
</blockquote>
So I tried to remove the whole node_modules and still got the same error. And looking at package.json of node_modules/mongodb, its version is still 1.4.26, not latest 2.1.7.
Apparently my mongodb comes as a dependency of another package I installed: sails-mongo. Modifying the package.json of sails-mongo and redoing npm install finally solve the issue.

I realize this thread is 1 year + old, but it helped me, albeit with a different module.

I installed mongoose-post-findv0.0.2 and this issue started. To fix it, I used the suggestions and navigated to \node_modules\mongoose-post-find\node_modules\bson\ext and opened the index.js file.

The file starts off with a try catch block trying to require the correct bson version

<pre><code>try {
 // Load the precompiled win32 binary
 if(process.platform == "win32" &amp;&amp; process.arch == "x64") {
 bson = require('./win32/x64/bson'); 
 } else if(process.platform == "win32" &amp;&amp; process.arch == "ia32") {
 bson = require('./win32/ia32/bson'); 
 } else {
 bson = require('../build/Release/bson'); 
 } 
} catch(err) {
 // Attempt to load the release bson version
 try {
 bson = require('../browser_build/bson');
 } catch (err) {
 console.dir(err)
 console.error("js-bson: Failed to load c++ bson extension, using pure JS version");
 bson = require('../lib/bson/bson');
 }
}
</code></pre>

this is the corrected version. What was happening is it tried to load bson from ../build/Release/bson, couldn't find it and fell into the catch. There is tried to load bson again from ../build/Release/bson and of course failed. So I changes the path in the catch to look in ../browser_build/bson. This resolved the error.

I post this for completeness.

blocks|key|2003920|text|在我们的例子中，没有找到c%2B%2B版本bson的原因是因为我们支持一个企业代理，而BSON构建过程中的一些东西需要伸出手来获取文件。当我们查看node_modules/bson/builderror.log时，我们看到了这样一个错误：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2003921|gyp+WARN+install+got+an+error,+rolling+back+install+gyp+ERR!+configure+error+gyp+ERR!+stack+Error:+connect+ECONNREFUSED+gyp+ERR!+stack+++++at+errnoException+(net.js:904:11)+gyp+ERR!+stack+++++at+Object.afterConnect+[as+oncomplete]+(net.js:895:19)|offset|length|style|CODE|2003922|这意味着代理可能是问题所在。设置http_proxy和https_proxy环境变量可以解决这个问题。|2003923|很抱歉重新唤醒了这方面的评论，但我想把这个张贴给任何其他人，在未来击中这一点，因为这条线是非常有助于解决我们的问题。|2003924|entityMap^0|0|0|6U|0|0|0^^$0|@$1|2|3|4|5|6|7|N|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|O|8|@$D|P|E|Q|F|G]]|9|@]|A|$]]|$1|H|3|I|5|6|7|R|8|@]|9|@]|A|$]]|$1|J|3|K|5|6|7|S|8|@]|9|@]|A|$]]|$1|L|3|-4|5|6|7|T|8|@]|9|@]|A|$]]]|M|$]]

In our case, the reason that the c++ version bson was not found was because we were behind a corporate proxy and something in the BSON build process needs to reach out to fetch files. When we looked in node_modules/bson/builderror.log, we saw an error like this:

<code>
gyp WARN install got an error, rolling back install
gyp ERR! configure error
gyp ERR! stack Error: connect ECONNREFUSED
gyp ERR! stack at errnoException (net.js:904:11)
gyp ERR! stack at Object.afterConnect [as oncomplete] (net.js:895:19)
</code>

Which suggested that the proxy might be the issue. Setting the http_proxy and https_proxy environment variables solved it.

Sorry for reawakening comments on this, but I wanted to post this for anyone else that hits this in the future since this thread was very helpful in solving our issue.

<blockquote>
 "Error: Cannot find module '../build/Release/bson'"
</blockquote>

Got it fixed by below steps :

<blockquote>
 <ol>
 <li>Create folder "Release" inside "node_modules\bson\build\" location</li>
 <li>Copy bson.js from "node_modules\bson\browser_build\" </li>
 <li>Paste bson.js inside "node_modules\bson\build\Release" folder.</li>
 </ol>
</blockquote>

This will resolve the issue. 

PS : I am using mongoose version 4.8.8 .

Thanks :) , hope it helps someone .

I solved this error by doing this and it perfectly worked for me. I have created a node App which has the folder node-android/node-modules.So here inside the node-modules directory I have one more directory bson/ext/index.js open this file and you can find inside the catch block.

<pre><code>bson = require('../build/Release/bson'); 
</code></pre>

change the above line to 

<pre><code>bson = require('../browser_build/bson');
</code></pre>

and the error was gone for me and the app is running perfectly without any errors or warnings.

Deploying Keystone JS CMS I had same error and I think most elegant solution is this:

Install <code>npm-check-updates</code>:

<pre><code>root@keystonejs:~# npm install -g npm-check-updates
</code></pre>

Within your keystone site directory, where <code>package.json</code> is placed, check dependencies:

<pre><code>debian@keystonejs:~/myproject/manalcjim$ npm-check-updates -u
</code></pre>

Then update all packages:

<pre><code>debian@keystonejs:~/myproject/manalcjim$ npm install
</code></pre>

And finally if you chose <code>jade</code> for templates, maybe you will need install <code>jade</code> module explicitly:

<pre><code>debian@keystonejs:~/myproject/manalcjim$ npm install jade --save
</code></pre>

I tried this in mongo-sync version 4.1.2 

but they made some changes and it is not working with the solutions provided here 

the solution which worked for me 

Path node_modules/mongo-sync/node_modules/bson/ext/index.js

Old Code

<pre><code>try {
 // Load the precompiled win32 binary
 if (process.platform == "win32" &amp;&amp; process.arch == "x64") {
 bson = require('./win32/x64/bson');
 } else if (process.platform == "win32" &amp;&amp; process.arch == "ia32") {
 bson = require('./win32/ia32/bson');
 } else {
 bson = require('../build/Release/bson');
 }
} catch (err) {
 // Attempt to load the release bson version
 try {
 bson = require('../build/Release/bson');
 } catch (err) {
 console.dir(err)
 console.error("js-bson: Failed to load c++ bson extension, using pure JS version");
 bson = require('../lib/bson/bson');
 }
}
</code></pre>

Change in the try block (copy the bson initialization from catch block)

<pre><code>bson = require('../lib/bson/bson');
</code></pre>

So it will look like

<pre><code>try {
 // Load the precompiled win32 binary
 if(process.platform == "win32" &amp;&amp; process.arch == "x64") {
 bson = require('./win32/x64/bson'); 
 } else if(process.platform == "win32" &amp;&amp; process.arch == "ia32") {
 bson = require('./win32/ia32/bson'); 
 } else {
 bson = require('../build/Release/bson'); 
 } 
} catch(err) {
 // Attempt to load the release bson version
 try {
 bson = require('../lib/bson/bson');
 } catch (err) {
 console.dir(err)
 console.error("js-bson: Failed to load c++ bson extension, using pure JS version");
 bson = require('../lib/bson/bson');
 }
}
</code></pre>

blocks|key|2004106|text|首先，我在npm模块mongodb中找到了文件index.js+index.js|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2004107|并在catch块中将路径更改为js版本。|2004108|bson+=require(‘./build/require/+bson’)；to+bson=require(‘./browser_build/bson’)；|2004109|但后来我就这样改变了一切类似的..。以前安装的模块..。*+bson+=要求(“bson”)；|2004110|entityMap^0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|J|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|K|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|L|8|@]|9|@]|A|$]]|$1|F|3|G|5|6|7|M|8|@]|9|@]|A|$]]|$1|H|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|I|$]]

First I just find in npm module mongodb the file index.js ..node_modules\mongodb\node_modules\bson\ext\index.js

and change path to js version in catch block

bson = require('../build/Release/bson');
to bson = require('../browser_build/bson');

but then I just changed it like this, all the similar... previously installed the module... : 
bson = require('bson');

blocks|key|2004130|text|我也有这个问题。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2004131|但是我将我的mongodb版本更改为"%5E2.2.33“，不再有问题了。|offset|length|style|BOLD|2004132|您应该在全局或本地上npm+rm您的旧mongodb包并安装此版本。|CODE|2004133|如果任何人不想改变方向名称有任何副作用，可以尝试此方法。|2004134|entityMap^0|0|6|7|J|7|0|A|6|0|0^^$0|@$1|2|3|4|5|6|7|O|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|P|8|@$D|Q|E|R|F|G]|$D|S|E|T|F|G]]|9|@]|A|$]]|$1|H|3|I|5|6|7|U|8|@$D|V|E|W|F|J]]|9|@]|A|$]]|$1|K|3|L|5|6|7|X|8|@]|9|@]|A|$]]|$1|M|3|-4|5|6|7|Y|8|@]|9|@]|A|$]]]|N|$]]

I also have this problem.

But I change my mongodb version to "^2.2.33" and no longer have the problem.

You shoud <code>npm rm</code> your old mongodb package on global or local and install this version.

If anyone don't want to have any side-effect on changing the direction name could try this method.

I am getting the below error:

<pre><code>{ [Error: Cannot find module '../build/Release/bson'] code: 'MODULE_NOT_FOUND' } 
 js-bson: Failed to load c++ bson extension, using pure JS version
</code></pre>

Here are my version details:

<ul>
<li>OS: Windows 7</li>
<li>MongoDB: 2.6.5</li>
<li>Node: 0.12.0</li>
</ul>

I have tried these things before I posted the issue here.

<ol>
<li>I went to <code>\node-modules\mongoose\node-modules\mongodb\node-modules\bson</code> folder and made below change in the binding-gyp file
from <code>'include_dirs': [ '&lt;!(node -e "require(\'nan\')")' ]</code>
to 
<code>'include_dirs': ["&lt;!(nodejs -p -e \"require('path').dirname(require.resolve('nan'))\")"]</code></li>
<li>Ran this command <code>npm install -g node-gyp</code></li>
<li>I've updated the mongoose version to 3.8.21 inside <code>package.json</code></li>
</ol>

Nothing works. Please suggest
