pipenv install <package> fails when PIP_EXTRA_INDEX_URL environment variable is set (from version 2021.11.23)

[ngiind]

Issue description

Pipenv 2021.11.23 fails when I try to install a package using pipenv install , if the environment variable PIP_EXTRA_INDEX_URL is set. I get the same problem in both windows and the ubuntu-latest docker image.

The following works:

• "pipenv install" with the package listed in Pipfile
• unsetting PIP_EXTRA_INDEX_URL
• rolliong back to 2021.11.15

Expected result

Package installed and added to Pipfile

Actual result

Package not installed and not added to Pipfile. Error message:

From cdde3f7:

indexes = list(filter(None, [index_url, *extra_index_url]))

Unset PIP_EXTRA_INDEX_URL environment variable and it should solve the problem while this is not fixed.
