title: Updating skeletons in pycharm and kivy
body: <p>I want to use kivy in pycharm. After I add python.bat in "Project Interpreter", it takes about 20 min to Update skeletons. Everything is ok till here but after I close <code>pycharm</code> and open again, <code>pycharm</code> wants to update skeletons again forcing me to wait for 20 min everytime.
  What should I do?</p>
