  command line will recognize npm's global path. Also install gulp so run
  command as gulp will be recognized. At the end, you'll have to restart the

      <li><code>%PROGRAMFILES(x86)%\Git\bin</code></li>
      <li>
        <span style="font-family: monospace">%PROGRAMFILES(x86)%\Git\cmd</span>
      </li>
    </ul>
    <li><span style="font-family: monospace">Or Maybe&nbsp;</span></li>
    <ul>
      <li><code>%PROGRAMFILES%\Git\bin</code></li>
      <li>
        <span style="font-family: monospace">%PROGRAMFILES%\Git\cmd</span>
      </li>
    </ul>
  </ul>
</ul>
<h3>How to enable yo?</h3>
<p>
  It is the same as bower at this point, you will need to install yeoman as
  globally.
</p>
<ul>
  <li><code>npm install -g yo</code></li>
</ul>
<p>
  If you can't install yo and command line display error contains as
  <code
    >If you are behind a proxy, please make sure that the 'proxy' config is set
    properly</code
  >. Try run <code>npm config ls -l</code>, this command will show all the
  config setting for npm, check the proxy, if the proxy is <code>null</code>,
  change it to <code>http://registry.npmjs.org/ </code> as following command.
</p>
<pre class="language-xml">
npm config set registry http://registry.npmjs.org/
</pre>
<h2>Still not working!?</h2>
<p>
  Before trying to figure out what's happening, restart your command line again,
  might works. Also, it is better to use Node.js command prompt.

<h2>Add <em>Start in (optional)</em> at Job Actioni tab</h2>
<p>
  By default, task schedular will run application with
  <code>/sytem32/</code> folder. I don't think that's the application location,
  so you can go Task Schedular, open your job. Open Actions tabl, at Start in
  (optional), type the application path.
