Python导入错误ModuleNotFoundError：停电后没有名为“ _ctypes”的模块

Question

There was a power outage in my area while i was working on a python script.After this happened, there was an error when i tried to import numpy.

ModuleNotFoundError: No module named '_ctypes'

In Pycharm,Project-> Settings ->Interpreter ,the package list is empty. Also, pip install produces this error,

Traceback (most recent call last):
  File "C:\Users\soc\Anaconda3\Scripts\pip-script.py", line 6, in <module>
    from pip._internal import main

    USER_CACHE_DIR = appdirs.user_cache_dir("pip")
  File "C:\Users\soc\Anaconda3\lib\site-packages\pip\_internal\utils\appdirs.py", line 38, in user_cache_dir
    path = os.path.normpath(_get_win_folder("CSIDL_LOCAL_APPDATA"))

    import _winreg
ModuleNotFoundError: No module named '_winreg'

Everything was working as expected before this incident.What could have changed due to power outage? How can i fix this this?

Answer 1

I saw a question very similar yours. Maybe it could help you:

importError: no module named _winreg python3

As it says in the _winreg documentation, it has been renamed to winreg in Python 3.0. You should run the 2to3 tool if you're converting code that was written for Python 2.x.
