title: Vim Error E492 - Not an editor command: PluginInstall
body: <p>I am trying to install Vundle on my Macvim. I followed the following <a href="https://github.com/gmarik/Vundle.vim" rel="noreferrer">link</a> to get Vundle. I also configured my .vimrc file. But when I try PluginInstall, I get the following error.</p>
  
  <pre><code>E492: Not an editor command: PluginInstall
  </code></pre>
  
  <p>My .vimrc contains the following:</p>

  </code></pre>
  
  <p>I also checked <a href="https://stackoverflow.com/questions/24185580/vundle-e492-not-an-editor-command-plugininstall">this</a> stackoverflow post. But it didn't solve my problem. Why does it throw such an error and how can I find what exactly is my issue.</p>
