Common Problems For Windows Users
---------------------------------
``/usr/bin/env: python: Permission denied.``
If you're in Git Bash, please check the python executable location by run ``which python``.
If the executable is under ``~/AppData/Local/Microsoft/WindowsApps/``, then it's a link to Windows AppStore, not a real one.
Please install python manually and update this in your ``PATH`` environment variable.
Your %USERPROFILE% contains non-ASCII characters
``pre-commit`` may fail when initializing an environment for a particular hook when the path of ``pre-commit``'s cache contains non-ASCII characters. The solution is to set ``PRE_COMMIT_HOME`` to a path containing only standard characters before running pre-commit.
- CMD: ``set PRE_COMMIT_HOME=C:\somepath\pre-commit``
- PowerShell: ``$Env:PRE_COMMIT_HOME = "C:\somepath\pre-commit"``
- git bash: ``export PRE_COMMIT_HOME="/c/somepath/pre-commit"``
