reportMissingImports Python error but import works fine

Question

When I install package with python and import it, I often get a missing imports message such as:

Import "fastapi" could not be resolvedPylancereportMissingImports

The imports always work perfectly fine, the fastapi example above will run a server and I can build an API without issue.

Can anyone explain why I am getting this error and how I could get rid of it?

Answer 1

The causes could be:

1. The name of the file - fastapi.py, if you name it in this could way you would get import errors. (Avoid filenames similar to package names)
2. Installing on other environments. Most of the time it happens when you use both Conda and PiP on you system.
3. If you run the code from VS Code, check if the same interpreter is selected.

Verify the installation:

$ pip list | grep fastapi

Suggestions:

OPT Virtual Environments to avoid these troubles.

Thank you!
