How to fix ModuleNotFoundError: No module named ' ' in Python on Windows, Linux, and macOS

This video will show you how to fix ModuleNotFoundError: No module named ' ' when using importing packages or modules in Python. I will go over fixing the error on Windows, Linux, and macOS. We will fix the issue by looking at three solutions to common problems. The first is installing the package or module using pip. If that does not work, then we will verify the installation path for the package or module. This step can be helpful if you have multiple versions of Python installed like Python 3.6, 3.7, 3.8, and 3.9. If after these steps, you are still getting the same error, we will see if any virtual environments are being used. Often people will install packages inside of virtual environments and then try to run their programs outside of the virtual environment. This will not work since all of the packages have been installed in the virtual environment. A similar issue can occur when people do not activate their environments before starting their programs.

This was a huge help- I couldn't figure out why a module wouldn't import, even though I had installed it. Yours was the only video I could find that mentioned installing separately in the virtual environment- once I did that, it worked perfectly. Thanks so much!

Alfrado. On linux I'm doing conda env create -f environment.yml. This command runs into a problem because when it uses python -m /path/pip instead of python -m pip. It is causing the ModuleNotFoundError with the first 2 subdirectories of path. I am using python3.8. Why it is tagging the path to pip onto its name is what I am trying to figure out. I can recreate this problem using python -m /path/pip. Any ideas?
