Error when importing pytest module on replit

[riquelmy]

Hello guys, I am getting the ModuleNotFoundError: No module named 'pytest' error when trying to import pytest on replit.

Traceback (most recent call last):
  File "main.py", line 2, in <module>
    from pytest import main
ModuleNotFoundError: No module named 'pytest'
exit status 1

What can I do? It seems I am not the only one going through this problem recently, this guy also reported the same issue link.

Thank you for this amazing learning platform, and I hope you all can give us a solution.

Scientific Computing Arithmetic Formatter Project error: no module named pytest

This thread covers your problem (but with modules like numpy and pandas, instead of pytest). In your case, the key difference is that the line you need to add is pkgs.python38Packages.pytest. Once done, your replit.nix file should look like this: { pkgs }: { deps = [ pkgs.python38Full pkgs.python38Packages.pytest ]; env = { PYTHON_LD_LIBRARY_PATH = pkgs.lib.makeLibraryPath [ # Needed for pandas / numpy pkgs.stdenv.cc.cc.lib pkgs.zlib # Needed for pygame…

I think someone gave a working solution.
