title: Vim plugin youcompleteme error message
body: <p>Every time I write a new python source code <code>*.py</code>, the following error message comes up:</p>
  
  <pre><code>Error detected while processing BufRead Auto commands for"*.py":
  E518:Unknow option:set
  E28:No such highlight group name: BadWhitespace
  </code></pre>
  
  <p>How can I fix it?</p>
  
  <p>Before I typed this question , I modified my <code>_vimrc</code> file according to <a href="https://stackoverflow.com/questions/36741450/vim-setting-error-under-bufread">this post</a>, but the error message remains. Even worse another error message occurs as well:</p>
  
  <p><code>The ycmd server SHUT DOWN(restart with':YcmRestartSever').YCM core library not detected;you need to compile YCM before using it. Follow the instructions in the documentation.</code></p>
  
  <p>I am a new Gvim user and I use gVim 8.0 in Windows 10. I set up my python development environment by searching the Internet and I installed the YouCompleteMe plugin via Vundle but It is too difficult for me to compile YCM myself now.</p>
