running pre-commit python package in Windows gives ExecutableNotFoundError: Executable `/bin/sh`-CodePudding

I am working on a project where pre-commit==2.15.0 was added to the python requirements file. I installed the requirements. Now when I try to do a git commit I get the following error:

An unexpected error has occurred: ExecutableNotFoundError: Executable `/bin/sh` not found
Check the log at C:\Users\username\.cache\pre-commit\pre-commit.log

In my pre-commit log I have:

pre-commit version: 2.15.0
sys.version:

I work in Windows where my teammates work on Macs.

It looks like precommit is trying to reference the /bin/sh script which is not in Windows. How do I get this precommit working?

CodePudding user response：

your previous git hook is using a non-portable shebang (#!/bin/sh) (in your case this file will be located at .git/hooks/pre-commit.legacy -- originally .git/hooks/pre-commit)

if you adjust the tool to use #!/usr/bin/env sh then pre-commit will be able to run it (even on windows)

alternatively, if you don't want to use pre-commit in migration mode run pre-commit install --force

you're also using an outdated version of pre-commit which may be contributing to your issues -- so I'd recommend upgrading that was well

disclaimer: I created pre-commit
