Pipenv fails to install a package when non-existent env variables are used in package URL on windows

[souris4science]

Issue description

As mentioned in the documentation, you may inject credentials into the URL of a package as environment variables. But in case these variables do not exist, the user is not prompted for username and password, but instead the operation fails with authentication error. The problem occurred on windows 10 host with Python 3.8.6-64-bit and pipenv 2020.11.15.

Expected result

Non-existent env variables should be replaced with empty strings and a request to https://:@github.com/myaccount/myproject.git would pop-up a window asking the user to provide the username and password.

Actual result

Package installation fails with authentication failure:

Steps to replicate

---

On Windows with the env variables GITHUB_USER and GITHUB_PASS unset, run the following on an empty project:

>py -3.8-64 -m pipenv install -e "git+https://${GITHUB_USER}:${GITHUB_PASS}@github.com/myaccount/myproject.git#egg=myproject"

$ pipenv --support

@souris4science Have you tried with pipenv==2022.1.8? I expect it might be the same because subprocesses are used in the install and locking process, so I am not sure it is viable to popup a UI prompting you for your username and PW

@matteius I gave it a try today and the problem still occurs with pipenv==2022.1.8.
