Install pygame using the python interpreter used by bazel.
~/.cache/bazel/_bazel_<user>/<hash>/execroot/rules_python/bazel-out/k8-fastbuild/bin/gazelle/std_modules.runfiles/python_3_10_9_x86_64-unknown-linux-gnu/bin/python3 -m pip install pygame

Pass pygame to the std_modules script:
echo "pygame" | bazel run //gazelle:std_modules

Expected:

Output should be false.

Actual:

Output is

pygame 2.1.2 (SDL 2.0.16, Python 3.10.9)
Hello from the pygame community. https://www.pygame.org/contribute.html
true

Cause: pygame/pygame#542

However, this could be any module that prints to stdout upon import of the module.

🔥 Exception or Error

Here is the exception gazelle throws:

gazelle: Error checking if standard module:  strconv.ParseBool: parsing "pygame 2.1.2 (SDL 2.0.16, Python 3.10.6)": invalid syntax
