I'm trying to figure out an import error, I'm having problems importing a module during a test.

tests/test_hyperspec.py F                                                [100%]

I can see the files there, but i can't seem to actually import the module

$ find sphinxcontrib tests 
sphinxcontrib
sphinxcontrib/cldomain.lisp
sphinxcontrib/cldomain.py
sphinxcontrib/test.lisp
sphinxcontrib/__init__.py
sphinxcontrib/package.lisp
sphinxcontrib/hyperspec.py
sphinxcontrib/version.lisp-expr
tests
tests/test_cldomain.py
tests/__init__.py
tests/__pycache__
tests/__pycache__/__init__.cpython-38.pyc
tests/__pycache__/test_cldomain.cpython-38-pytest-7.1.2.pyc

I went into the directory directly and tested with a local python and with the sandbox python, but the cached one can't import stuff? I commented out the contents of the files completely, to make sure it wasn't an issue with loading them

$ cd /tmp/.tmpDGxM5D

any idea what could be going on? i'm on pants 2.12.0

Does it show up if you run

./pants dependencies tests/test_hyperspec.py

?

yeah i get

$ ./pants dependencies tests/test_hyperspec.py
15:02:26.55 [INFO] Initializing scheduler...

I’m not sure, but I think it could be due to that you had put more than one distribution in the requirements field. The

python_requirement

target is meant for a single dist per target only. https://www.pantsbuild.org/docs/reference-python_requirement#coderequirementscode

ah ok, good to know

python_requirements

are usually used to source a

requirements.txt

file into corresponding

python_requirement

targets, which is preferable if you have more than a few 3rdparty dependencies.

Isn't this all just down to the name of the

python_requirement

being the name used for dep inference? IOW you could also correct by adding module mappings for all requirements. Not that you'd want to do this, just to avoid misunderstanding what was going on there (the assumption being

sphinxcontrib

was using

pkg_resources

to effect a namespace package).

if i'm using

python_requirements

to declare my library dependencies, do i also need to declare them in the

setup.cfg

? or does it propagate through?
