ModuleNotFoundError

[colingoodman]

At some point in the last few months pytest broke in an existing repo of mine. I am currently using Python 3.9, Pytest 7.1.2. Running pytest or python -m pytest yields

...
/path/project/test/test_main.py:1: in <module>
    ???
../../venv/lib/python3.9/site-packages/fastapi/testclient.py:1: in <module>
    from starlette.testclient import TestClient as TestClient  # noqa
../../venv/lib/python3.9/site-packages/starlette/testclient.py:16: in <module>
    import requests
E   ModuleNotFoundError: No module named 'requests'

I am using FastAPI (accordingly basing my tests originally off this) among a few other libraries in this project. All of them are installed properly in my venv; I can run the project with no issues.

I found this suggestion online of removing pytest from my global pip packages, but it did not resolve the problem. I have also tried adding and removing __init__.py files in the tests directory and the main project directory with no success

Thank you for for any help/suggestions.

What does importing request standalone do? It seems like there is a problem being hidden by the error handling

Your suggestion lead me here where I found out that the Starlette testclient class requires requests, but this oddly doesn't get installed as a dependency by anything. Installing requests fixed this. Thanks!
