title: pip install -U setuptools fail windows 10
body: <p>I just installed Python3.7 and Pycharm on my Windows 10 PC.
  I am running pip version 9.0.2</p>
  <p>In Pycharm, it says I have version 28.8.0 of setuptools, when I try to upgrade this in Pycharm, which I believe runs the line</p>
  <pre><code>pip install -U setuptools
  </code></pre>
  <p>I get the error:</p>
  <blockquote>
  <p>PermissionError: [WinError 32] The process cannot access the file because it
  is being used by another process:
  'c:\users\Username\pycharmprojects\untitled1\venv\lib\site-
  packages\setuptools-28.8.0-py3.6.egg' -&gt;
  'C:\Users\Username\AppData\Local\Temp\pip-i5jxitem-
  uninstall\users\Username\pycharmprojects\untitled1\venv\lib\site-
  packages\setuptools-28.8.0-py3.6.egg'</p>
  </blockquote>
  <p>I have tried running</p>
  <pre><code>pip install --upgrade setuptools
  </code></pre>
  <p>which runs successfully and says I have the latest version.</p>
  <p>Does anyone know how I can successfully update setuptools?</p>
  <p>The reason I'd like setuptools to be up to date, is so I can then get rid of the egg_info error installing other packages.</p>
