title: 'Pip' recognized in Command Prompt but not in PyCharm terminal
body: <p>When I try to run pip in the Windows Command Prompt, <code>pip -V</code> works fine, but when I try to run it in PyCharm terminal I get <code>'pip' is not recognized as an internal or external command, operable program or batch file.</code></p>
  
  <p>My Path environmental variables are set for:</p>
  
  <pre><code>C:\Users\username\AppData\Local\Programs\Python\Python37\Scripts\
  C:\Users\username\AppData\Local\Programs\Python\Python37\
  C:\Users\username\AppData\Roaming\Python\Python37\Scripts\
  C:\Users\username\AppData\Roaming\Python\Python37\
  </code></pre>
  
  <p>The main difference I can think of is that the PyCharm terminal and project opens on <code>D:</code>, and my path variables are set to <code>C:</code> but I don't know why that would affect it. I have recently uninstalled and reinstalled both PyCharm and Python (a previous version) if that helps, but I made it a point to not import any settings.</p>
