title: Pip install tesseract-ocr : failed with exit status 2
body: <p>I've been trying to install Tesseract-ocr library for a long time. Read many similar problems related with other packages and given solutions and none worked. </p>
  
  <p>I think problem is about the my Microsoft Visual Studio. There is an error given the code below:</p>
  
  <blockquote>
    <p>error: command 'c:\Program Files (x86)\Microsoft Visual Studio
    10.0\VC\Bin\x86_amd64\cl.exe' failed with exit status 2</p>
  </blockquote>
  
  <p>I uninstalled, reinstalled, updated and tried many things but still not working :(</p>
  
  <p>Thanks already now!</p>
