title: Could not install packages due to an OSError: [WinError 2] No such file or directory
body: <p>I try to use pip to install numpy, and I receive the following error message:</p>
  <blockquote>
  <p>Python: Could not install packages due to an OSError: [Errno 2] No such file or directory
  'c:\python39\Scripts\f2py.exe' -&gt; 'c:\python39\Scripts\f2py.exe.deleteme'</p>
  </blockquote>
  <p>I'm not sure about an older version of numpy installed first.</p>
  <p>I ran just command prompt, not a one with admin privileges.</p>

  <p>Can anyone help? Thanks.</p>
