pre-commit fails to install isort 5.11.4 with error "RuntimeError: The Poetry configuration is invalid"

pre-commit suddenly started to fail installing the isort hook in our builds today with the following error

[INFO] Installing environment for https://github.com/pycqa/isort.
[INFO] Once installed this environment will be reused.
[INFO] This may take a few minutes...
An unexpected error has occurred: CalledProcessError: command: ('/builds/.../.cache/pre-commit/repo0_h0f938/py_env-python3.8/bin/python', '-mpip', 'install', '.')

      RuntimeError: The Poetry configuration is invalid:

It seems to be related with poetry configuration..

Solution

  • Upgrading the hook to the freshly released isort 5.12.0 seems to be fixing the issue.

    Looking at the commit stack from isort repo, it sounds like recent version of Poetry had a breaking change incompatible with isort <= 5.11.4 (commit)
