python - pycharm reports an error when running: unable to load the file system codec ImportError?

Question

I installed several versions of python before, but I uninstalled them all because they were too messy. Now after installing python3.4.3,
it works fine when typing python in cmd

But an error is reported when running an empty file in pycharm
Error message:
Fatal Python error: Py_Initialize: unable to load the file system codec
ImportError: No module named 'encodings'

Answer 1

Set your python interpreter path in the project structure in pycharm. If it still doesn't work, add environment variables to the running of python. If it doesn’t work, you can try to install this module through the install repo in pycharm

Answer 2

Install it once with administrator rights, and then try configuring the environment variables
