Missing pip dependencies with venvs_site_packages=yes

Comece com a regra py_test e reproduza a falha de logger_tests_py_test descrita no traceback, usando venvs_site_packages=yes. Inspecione o ambiente virtual gerado e o tratamento de dependências de pytest, py, pluggy e iniconfig; a issue estará concluída quando os pacotes transitivos exigidos por pytest estiverem presentes de forma consistente e o target for executado com sucesso.

🐞 bug report

Affected Rule

The issue is caused by the rule: `py_test`

Is this a regression?

No

Description

Pip dependencies are missing for py_test targets.

1. Ex: pytest pip package depends on py pip package. Adding pytest to the deps for py_test doesn't include its transitive dependencies, e.g. py (and others). It does include some transitive dependencies though, e.g. pluggy
2. In the above example, adding py as an explicit dependency in deps fixes the problem as it gets included in the generated venv. However, this 'fix' doesn't work for iniconfig, another missing transitive dependency of pytest - it doesn't get included in the venv
