title: MODULE_NOT_FOUND error on npm install
body: <p>I deleted the local folder which contained <code>bluebird</code> on my system using:</p>
  
  <p><code>rm -rf &lt;module_path&gt;</code></p>
  
  <p>And now when I try to install it again using:</p>
  
  <p><code>npm install bluebird</code> or <code>npm install bluebird --save</code> I get the following error everytime:</p>
  
  <pre><code>npm ERR! code MODULE_NOT_FOUND
  npm ERR! Cannot find module 'bluebird'
  </code></pre>
  
  <p>I'm kind of stuck here because the only way I can think of fixing the error is by installing bluebird but I can't install it because of the above error.</p>
