Was trying to get together the code for a potential

WSDL -> Java

codegen backend and I’m getting an import error when doing

./pants test src/python/pants/backend/codegen/soap::

on a fresh pull of the

pants

repo (well, in fact it happens when I try running any Python test using the

./pants

script). The error looks like the following:

_ ERROR collecting src/python/pants/backend/codegen/soap/target_types_test.py __
ImportError while importing test module '/private/var/folders/c9/5v4gbjh17w9_vy73fc90fnch0000gn/T/process-executionF88I01/src/python/pants/backend/codegen/soap/target_types_test.py'.
Hint: make sure your test modules/packages have valid Python names.

I did a

./cargo build

and

./cargo test

separately and those commands succeed … does any of know what I may be missing that causes that error?

Hi, No idea. A hunch I’m getting is if it could be related to

__init__.py

files missing, or some such, maybe.. do you see the same issue on a clean checkout from

main

as well?

yeah, that’s the odd thing, it happens in all packages…

I’d try a clean checkout, and wiping

~/.cache/pants

in case there’s some flunky data in there.. That will start you over from scratch. (N.b. that if you have any pantsd processes running, you need to kill them too..)

unfortunately it still happens …

I think this may be because you're using the MacOS system python, which is known to have all sorts of quirks and flaws

pants seems to still prefer using my system-wide Python instead of the one installed by pyenv, even though the latter is before is in the

PATH

https://www.pantsbuild.org/v2.11/docs/reference-python-bootstrap You can set that in

~/.pants.rc

I think. https://github.com/pantsbuild/pants/pull/14142

Or just to verify that this solves things, try

--python-bootstrap-search-path="['<PYENV>']"

that works! I’ll drop that setting in a ~/.pants.rc file. Many thanks! 🙂
