Console scripts in virtual environment do not output to terminal in git bash
I have console scripts in my virtual environment in `\env\Scripts`, installed with packages (e.g. black, pytest, coverage). If I try to execute these in Git Bash, the output is not returned to the terminal. If I use the command line tool for e.g. black with a virtual enviroment activated in Git Bash, I get a blank line returned, but no response: ``` $ black version.py ``` If I invoke black through python, I get the expected response: ``` $ python -m black version.py All done! ✨ � ✨ 1 file left unchanged. ``` If I invoke the command line tool using black from the system interpreter (i.e. not using the virtual environment), I get the expected response: ``` $ black version.py All done! ✨ � ✨ 1 file left unchanged. ``` If I pipe the output to a file, I get the output in the terminal, but nothing in the file: ``` $ black version.py > test.txt All done! ✨ � ✨ 1 file left unchanged. ``` If I invoke the command line tool with Microsoft cmd, I get the expected response: ``` λ black version.py All done! ✨ � ✨ 1 file left unchanged. ``` If I invoke the command line tool with a blank virtual environment, I get the expected response. ``` $ python -m venv env $ . ./env/Scripts/activate $ pip install black $ black version.py All done! ✨ � ✨ 1 file left unchanged. ``` If I try to pip uninstall black, sys.stderr seems to be missing: ``` $ pip uninstall black Found existing installation: black 22.1.0 Uninstalling black-22.1.0: Would remove: c:\users\XXX\env\lib\site-packages\_black_version.py c:\users\XXX\env\lib\site-packages\black-22.1.0.dist-info\* c:\users\XXX\env\lib\site-packages\black\* c:\users\XXX\env\lib\site-packages\black_primer\* c:\users\XXX\env\lib\site-packages\blackd\* c:\users\XXX\env\lib\site-packages\blib2to3\* c:\users\XXX\env\lib\site-packages\c249b57082ff69932638__mypyc.cp39-win_amd64.pyd c:\users\XXX\env\scripts\black-primer.exe c:\users\XXX\env\scripts\black.exe c:\users\XXX\env\scripts\blackd.exe ERROR: Exception: Traceback (most recent call last): File "C:\Users\XXX\env\lib\site-packages\pip\_internal\cli\base_command.py", line 167, in exc_logging_wrapper status = run_func(*args) File "C:\Users\XXX\env\lib\site-packages\pip\_internal\commands\uninstall.py", line 97, in run uninstall_pathset = req.uninstall( File "C:\Users\XXX\env\lib\site-packages\pip\_internal\req\req_install.py", line 638, in uninstall uninstalled_pathset.remove(auto_confirm, verbose) File "C:\Users\XXX\env\lib\site-packages\pip\_internal\req\req_uninstall.py", line 363, in remove if auto_confirm or self._allowed_to_proceed(verbose): File "C:\Users\XXX\env\lib\site-packages\pip\_internal\req\req_uninstall.py", line 403, in _allowed_to_proceed return ask("Proceed (Y/n)?

I re-installed Git for Windows. I am using Python 3.9.9. It feels like an environment variable or something related to the PATH that messes up stderr/stdout. I understand this is a very specific situation, probably related to the repository that I am currently working on (which I installed in editable mode with `pip install -e .`). Could somebody point me in the right direction to fix this?
