[yili1992]

Issue description

I want to change PyPi index when creating virtual environment, but pipenv still to download package via default pypi source(files.pythonhosted.org)

pipenv install --pypi-mirror https://mirrors.163.com/pypi/simple

Expected result

when creating virtual environment , it will to download setuptools via https://mirrors.163.com/pypi/simple

Actual result

Installing setuptools, pip, wheel...

@yili1992 This should be solved with pipenv==2022.8.19 and the index package restrictions implemented earlier this year. Pass the --index argument though instead of --pypi-mirror to specify to use an index other than the default index in the Pipfile (which is the first source listed).
