No such file or directory error when installing types with mypy

Empieza reproduciendo poetry run mypy --config-file pyproject.toml con el entorno de Python 3.10 proporcionado y la configuración de [tool.mypy], especialmente las opciones files, exclude, install_types y non_interactive. Rastrea la ruta de instalación de tipos que produce el argumento /site-packages//google; se considera terminado cuando los paquetes de stubs requeridos se instalan sin esa ruta no válida y el análisis estático se completa en GitLab CI.

Bug Report

When running the command poetry run mypy --config-file pyproject.toml in GitLab CI, MyPy starts installing types as expected, but then throws an error:

mypy: can't read file '/root/.cache/pypoetry/virtualenvs/our-package-d4xTn211-py3.10/lib/python3.10/site-packages//google': No such file or directory

Expected Behavior

I would expect MyPy to install the required types and run the static analysis check.

Actual Behavior
