Summary of changes

Windows doesn't let you delete or overwrite a file that's being run. This causes errors when pipx manages itself with the following commands and the -all equivalent.

• pipx upgrade pipx
• pipx reinstall pipx
• pipx uninstall pipx

However, Windows does allow you to rename or move files that are in use. I utilize this by creating a folder at $PIPX_HOME/.trash to temporarily move files marked for deletion. The next time pipx runs, the folder will be deleted.

Note: reinstall has to use the --python option or set PIPX_DEFAULT_PYTHON because it uses $PIPX_HOME\venvs\pipx\Scripts\python.exe by default, which would end up being deleted. If it ends up using a python that would be deleted, the user will be notified and told to change it.

Test plan

Install pipx via pip, then the dev pipx via pipx

python -m pip install pipx
pipx install .

Then run some commands that would normally error:

pipx upgrade pipx
pipx reinstall pipx --python $(which python)
pipx uninstall pipx
