"TypeError: 'bool' object is not iterable" when installing current directory

[ErikBjare]

Issue description

Installed pipenv v2018.10.9 in my CI environment, then installed packages using pipenv install . -r requirements.txt (see stacktrace further down).

Managed to reproduce on my local machine after updating pipenv. Works fine in v2018.7.1. The -r requirements.txt was not necessary for the bug to get triggered, pipenv install . is enough to cause the bug.

Expected result

Successfully install all packages.

Actual result

pipenv install . -r requirements.txt
Courtesy Notice: Pipenv found itself running within a virtual environment, so it will automatically use that environment, instead of creating its own for any project. You can set PIPENV_IGNORE_VIRTUALENVS=1 to force pipenv to ignore that environment and create its own instead. You can set PIPENV_VERBOSITY=-1 to suppress this warning.
