<li>Downgrade to Node.js 0.6.12</li>

<li>Install Mocha as global</li>
<li>Add <code>./node_modules/.bin</code> to my <code>PATH</code></li>

since npm 5.2.0, there's a new command "npx" included with npm that makes this much simpler, if you run:

<pre><code>npx mocha &lt;args&gt;
</code></pre>

Note: the optional args are forwarded to the command being executed (mocha in this case)

this will automatically pick the executable "mocha" command from your locally installed mocha (always add it as a dev dependency to ensure the correct one is always used by you and everyone else).

Be careful though that if you didn't install mocha, this command will automatically fetch and use latest version, which is great for some tools (like scaffolders for example), but might not be the most recommendable for certain dependencies where you might want to pin to a specific version.

You can read more on npx <a href="https://blog.npmjs.org/post/162869356040/introducing-npx-an-npm-package-runner" rel="noreferrer">here</a>

<hr>

Now, if instead of invoking mocha directly, you want to define a custom npm script, an alias that might invoke other npm binaries...

you don't want your library tests to fail depending on the machine setup (mocha as global, global mocha version, etc), the way to use the local mocha that works cross-platform is:

<pre><code>node node_modules/.bin/mocha
</code></pre>

npm puts aliases to all the binaries in your dependencies on that special folder.
Finally, npm will add node_modules/.bin to the PATH automatically when running an npm script, so in your package.json you can do just:

<pre><code>"scripts": {
 "test": "mocha"
}
</code></pre>

and invoke it with

<pre><code>npm test
</code></pre>

While installing the node modules for mocha I had tried the below commands

<ul>
<li>npm install</li>
<li>npm install mocha</li>
<li>npm install --save-dev mocha</li>
<li>npm install mocha -g # to install it globally also</li>
</ul>

and on running or executing the mocha test I was trying 

<ul>
<li>mocha test</li>
<li>npm run test</li>
<li>mocha test test\index.test.js</li>
<li>npm test</li>
</ul>

but I was getting the below error as: 

'Mocha' is not recognized as internal or external command

So , after trying everything it came out to be just set the path to environment variables under the System Variables as:

C:\Program Files\nodejs\

and it worked :)

I'm having trouble getting <a href="http://visionmedia.github.com/mocha/" rel="noreferrer">Mocha</a> to work as expected, and I'd love to say as documented, but there (appears) to not be much documentation on actually getting the thing running.

I've installed it using <code>npm</code> (both globally and locally), and each time when I run it I get:

<pre><code>$ mocha
mocha: command not found
</code></pre>

Ok, so I figured it's not in my <code>PATH</code>, so I tried running it directly,

<pre><code>$ ./node_modules/mocha/bin/mocha 
execvp(): No such file or directory
</code></pre>

Finally, I tried hitting the other <code>bin</code> file, and got,

<pre><code>$ ./node_modules/mocha/bin/_mocha 
path.existsSync is deprecated. It is now called `fs.existsSync`.

 .

 ✔ 1 tests complete (1ms)
</code></pre>

How can I just execute my tests with a single command? <a href="http://vowsjs.org/" rel="noreferrer">Vows</a> seems to let you, but I've heard Mocha is the better choice, I just can't seem to get it working correctly.

And any thoughts on the error I got above in my third attempt?

Edit:

I'm running,

<ul>
<li>Ubuntu 11.10 64-bit</li>
<li>Node.js 0.7.5</li>
<li>npm 1.1.8</li>
<li>mocha 0.14.1</li>
<li>should 0.6.0</li>
</ul>

我遇到了让按预期工作的问题，我很想说，正如文档所述，但(似乎)没有太多关于让它实际运行的文档。我已经使用npm (全局和本地)安装了它，每次我运行它时都会得到：$ mochamocha: command not found好吧，我想它不在我的PATH里，所以我试着直接运行它，$ ./node_modules/mocha...
