title: Python external on Azure ImportError No Module Found
body: <p>If i locally run my code with python main.py, then this error occurs locally. If i run it with python3 main.py, it works as expected. I suspect my azure app service is not running the correct version of python, however, it is set to python 3.4 </p>

  <p>UPDATE</p>
  
  <p>So I went to the debug console in kudo and i ran python 
  <code>-m pip install --upgrade -r d:\home\site\wwwroot\requirements.txt</code>.</p>
  
  <p>Here is the error</p>
  
  <pre><code> ERROR: b"'xslt-config' is not recognized as an internal or external command,\r\noperable program or batch file.\r\n" ** make sure the development packages of libxml2 and libxslt are installed ** Using build configuration of libxslt
  </code></pre>
  
  <p>One of the requirements is Pillow which requires libxml2 and libxslt. I've tried using wheels however, I've had no success. </p>
  
  <p>UPDATE II
  I tried to install virtualenv since it does not exist and I receive a permissions error. </p>

  <p>UPDATE III
  I ran this command</p>
  
  <pre><code>D:\home\python364x64&gt;python -m pip install newspaper3k
  </code></pre>
  
  <p>I test everything locally, and it works perfect. I push and receive this error below.</p>
