ValueError on Windows when config is on a different drive than the git repo #2530
Description
search tried in the issue tracker
is:issue relpath
describe your issue
pre-commit will fail with ValueError: path is on mount 'C:', start on mount 'D:' when the config file is on C:\ but the git repository is on D:\
Steps to reproduce:
- Create config file on your
C:drive (for example%USERPROFILE%\.pre-commit-config.yaml) - Create git repo on
D:drive - Run pre-commit:
pre-commit run --config=%USERPROFILE%\.pre-commit-config.yaml
Commenting out line 164 in main.py (args.config = os.path.relpath(args.config)) fixes this issue. Is it necessary that the config path is relative to the working directory?
