Not finding bazel-installed python packages #21

Open michael-christen opened 1 week ago

michael-christen commented 1 week ago

I've noticed that packages installed outside of the typical requirements_lock.txt path, purely from other bazel repositories aren't being found when running mypy. If you look at the python_imports for a py_binary it seems like we'd want to append that list to MYPY_PATH.

Curious if others are seeing this or if it's just an issue with my setup.

mark-thm commented 1 week ago

When you say python_imports do you mean the values provided to the imports attribute of a py_binary?

Could you clarify Bazel, rules_python and rules_mypy versions you're running? If possible, a small repro would also be helpful (feel free to make a PR that adds another example or modifies the existing one to illustrate the issue).

Of course, thanks for the quick response.

Check out https://github.com/michael-christen/toolbox/tree/reproduce_bazel_dependency_issue and run

 bazel build examples/pigweed/tools:console

Here's an example of the output I'm getting:

But, if you look at the mypy_cache, it doesn't seem to be picking this bazel installed python repository up.

Bazel Version is ~ 7, a specific commit 0ddcfd327ffd012d348deeae08ec0836409706ad rules_python is 0.34.0 rules_mypy is 0.6.0

Thanks for the help, lmk if there's anything I can do.
