After pycharm New Project button gray issue

The same applies to import a new project can not run after someone else's problem

One reason:

　　pycharm not set the system parser

Solution one:

　　Open pycharm-> File-> Settings-> Project Interpreter-> Set python path (system python)

 

Cause two:

　　Do not create a new configuration

Solution two:

　　Open pycharm-> Run-> edit configuration -> [left corner] "+" sign (add new configuration) -> python

 

Or simply violent methods:

　　Right-click the run 'test'

　　Shortcut key ctrl + shift + F10
