WSL: pipenv shell does not launch a subshell

Issue description

WSL on Windows 10 with Ubuntu 18.04 On WSL the command ‘pipenv shell’ does not launch a subshell or activate the environment. Due to #3488, I had to uninstall all Windows versions of Python to have success at creating the environment.

Expected result

Launching subshell in virtual environment…
(env-setup) mfaine@MSSLW17050462:/mnt/c/Users/mfaine/Desktop/env-setup$

Actual result

Launching subshell in virtual environment…
mfaine@MSSLW17050462:/mnt/c/Users/mfaine/Desktop/env-setup$

Typing exit here will close the terminal. It is possible to to manually activate the environment without launching a subshell with:

source $(pipenv --venv)/bin/activate

Steps to replicate

pipenv shell has always worked as it should for me on WSL, with or without python installed in Windows, on three different computers.

@bromps I ‘solved’ it by recreating the environment with the WSL’s interpreter as was suggested, as I’m already using pipenv 2020.11.4.
