title: How to get flake8 in $PATH
body: <p>Windows 7 with Atom IDE. 
  Stick with me here, I'm new to using command line and atom.
  flake8 error while running python in atom. 
  terminal say file location for flake8 is: /c/Users/Parker/AppData/Local/Programs/Python/Python37/Scripts/flake8</p>
  
  <p>How do I get flake8 in my path for atom? I tried download the virtualenv and then abandoned that when I hit sudo:command not found. Figured there must be an easier way. </p>
  
  <p>How do I do this? Been trying different methods for days and have exhausted the search function.</p>
