note: This error originates from a subprocess, and is likely not a problem with pip.

Same issue here when using a default pip install of pqcrypto package. When installing it manually from a poetry output, a wheel file (.whl) using pip and which completes successfully, I get an error at import like:
from pqcrypto.kem.mceliece8192128 import generate_keypair, encrypt, decrypt
ModuleNotFoundError
My environment is Linux and conda.

Just found the reason for the error in my environment. The install via poetry wheel file worked Ok. In order to test it the code must be executed in a separate directory, not inside the project source directory. Imports are working fine. Sorry.
