Python test bindings don't work with setup.py #1358

Open knmcguire opened 8 months ago

knmcguire commented 8 months ago

If I install the python bindings via these instructions and run python tests with python3 -m pytest test_python/ I get the following error:

_____________________________________ ERROR collecting test_python/test_pptraj.py ______________________________________
ImportError while importing test module '/home/knmcguire/development/bitcraze/c/crazyflie-firmware/test_python/test_pptraj.py'.
Hint: make sure your test modules/packages have valid Python names.
Traceback:

    ???
E   ModuleNotFoundError: No module named '_cffirmware'

I'll need to put the python bindings in PYTHONPATH in order to make it work:
export PYTHONPATH=<PATH_TO_>/crazyflie-firmware/build:$PYTHONPATH

Hello. I am trying to solve this issue myself and I have a quick question. What is PYTHONPATH in this case?

knmcguire commented 7 months ago

not sure! but you can read it out by echo $PYTHONPATH 😄 its a collection of multiple paths in which python searches for any scripts. (this only works in ubuntu)
