- I am getting the error Import "_frozen_importlib" could not be resolved when using pytest and conda. Can someone please help?
Here is the error when I run python -m pytest
When I click on ..\..\..\..\anaconda3\envs\flaskblog2\lib\importlib\__init__.py:
from the pastebin above I get the file below.
In the file in the pastebin above I am getting the error Import "_frozen_importlib" could not be resolved.
I tried googling this and just can't seem to solve it.
Do you think this could be an error with conda?
Thanks for the help.
