Visual Studio Code ModuleNotFoundError：没有名为“_overlapped”的模块

Question

I have developed the following message when running flask. I attempted to add overlapped, via pip install overlap. I can't find answers to this. This is my terminal output. Can someone please help?

dvdjms@DESKTOP-OPG4GRH:/mnt/c/Users/dvdjm/Documents/CS50/project$ flask run
Usage: flask run [OPTIONS]
Try 'flask run --help' for help.

Error: While importing 'app', an ImportError was raised:

Traceback (most recent call last):
  File "/home/dvdjms/.local/lib/python3.8/site-packages/flask/cli.py", line 218, in locate_app
    __import__(module_name)

    import _overlapped
ModuleNotFoundError: No module named '_overlapped'

Answer 1

Did you mean to import NULL from asyncio.windows_event ? I'm guessing it was automatically imported by your IDE, None is likely what you're looking for instead of NULL , which isn't a keyword in Python.
