No such file or directory error when installing types with mypy

Commencez par reproduire poetry run mypy --config-file pyproject.toml avec l’environnement Python 3.10 fourni et les paramètres de [tool.mypy], en particulier les options files, exclude, install_types et non_interactive. Suivez le chemin d’installation des types qui produit l’argument /site-packages//google ; le travail est considéré comme terminé lorsque les packages de stubs requis s’installent sans ce chemin invalide et que l’analyse statique s’achève dans 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
