Issue description

Using latest Pypy3, but I doubt that has anything to do with my issue as I am able to install packages perfectly fine with other terminal emulators (Windows Terminal, Powershell) & Pipenv.

Expected result

Expected packages (ex. flake8) to install w/o error in Git Bash as they do in any other terminal.

Actual result

[WinError 6] The handle is invalid

Steps to replicate

• Using Git Bash, install pipenv w/ py -m pip install pipenv -U
• Attempt to install any package (ex. flake8) w/ pipenv install flake8
• Observe error.

---

pipenv --support result:

$ pipenv --support

Could you try if the master branch works for you?

$ git clone https://github.com/sarugaku/shellingham.git
$ cd shellingham/src
$ pypy3  # Or however you run the PyPy 3.7 installation in question.
>>> import shellingham
>>> shellingham.detect_shell()

There’s recently a substential rewrite on the Windows logic and I’m curious whether the new implementation still has the same issue.
