I think you forgot to setup the directory for express:
<pre><code>express &lt;yourdirectory&gt;
</code></pre>
Once you do that you should be able to see a bunch of files, you should then run the command:
<pre><code>npm install -d
</code></pre>

Node comes with npm installed so you should have a version of npm. However, npm gets updated more frequently than Node does, so you'll want to make sure it's the latest version.

<pre><code>sudo npm install npm -g
</code></pre>

Test: 

<pre><code>npm -v //The version should be higher than 2.1.8
</code></pre>

After this you should be able to run:

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

It by itself says that <code>package.json</code> is not available in your project.
So, to create <code>package.json</code>, use the following steps:

<ol>
<li>open command prompt on your project directory</li>
<li><code>npm init</code> (it will ask you to enter lots of entries like name, version, desc, etc., enter some random values and click enter).</li>
<li>type <code>yes</code> and click enter</li>

I found myself here trying to resolve the same error message:
<pre><code>npm ERR! message ENOENT, no such file or directory 'c:\&lt;some_folder&gt;\package.json'
</code></pre>
The error could be due to two reasons:
<ol>
<li>You do not have the package.json</li>
<li>You have the <code>package.json</code>, but you are running <code>npm start</code> in the wrong folder</li>
</ol>
To troubleshoot the first cause, you need to create a package.json using:
<pre><code>npm init
</code></pre>
To fix the second cause, make sure the folder you are running the <code>npm start</code> command is the same folder as the <code>package.json</code>

I was experiencing this identical error and terminal (foolishly, on my part) was in a parent directory instead of the correct one (where <code>package.json</code> was correctly located).
All I did in terminal was <code>cd [insert correct directory name here, overwriting brackets]</code> and that corrected the problem.

For the following command

<pre><code>sudo npm install react browserify watchify babelify --save-dev

I got same error

<blockquote>

But when I run the command

<pre><code>sudo npm install -gd react browserify watchify babelify --save-dev
</code></pre>

then no missing file or directory message appeared.

Please check the directory or the folder in which you're installing your new package.
This happened to me as well, 
My whole project was in a subdirectory and I was trying to install in the main directory. After checking the whole thing I found out that I had to install in the subdirectory where my project files and package.json files are located and it's done.
Hope this helps...

Generate package.json without having it ask any questions. I ran the below comment in Mac and Windows under the directory that I would like to create package.json and it works

I'm trying to install the dependencies of some example: npm's <code>express 2.5.8</code> that I've downloaded, but all of the apps throw the same error:

<pre><code>c:\node\stylus&gt;npm install -d

The blockage appears to be: 

<blockquote>
 no such file or directory 'c:\node\stylus\package.json
</blockquote>

Did I miss a step that creates the <code>package.json</code> ?

I'm running:

<ul>
<li>Windows 7 64 bit</li>
<li>npm 1.1.1</li>
<li>node 6.11</li>
<li>express 2.5.8</li>
</ul>

npm can't find package.json

Visual Studio

Windows

我正在尝试安装一些示例的依赖项:我下载的npm的express 2.5.8，但所有的应用程序都抛出了相同的错误：c:\node\stylus>npm install -dnpm info it worked if it ends with oknpm info using npm@1.1.1npm info using node@v0.6.11npm ERR! Couldn't read depe
