pipenv install --dev ansible-test fails to create lock file

[claudeleveille]

Issue description

pipenv fails to produce a lock file when installing the 'ansible-test' package.

Expected result

pipenv command exits with a zero status code and both Pipfile and Pipfile.lock are produced on the filesystem.

Actual result

Command output:

$ pipenv install --dev ansible-test --verbose

Steps to replicate

0. pipenv install --dev ansible-test (version 1.0.1, specifying version doesn't help).

My Pipfile (results from running above command):

[[source]]
url = "https://pypi.org/simple"
verify_ssl = true
name = "pypi"

[packages]

[dev-packages]
ansible-test = "*"

[requires]
python_version = "3.6"

Seems to be doing this same thing for every package now... Maybe it's my system.

[techalchemy]

Most likely you will need the changes is #2935 to see this work

[ghost]

@claude-leveille it's not your system, pipenv is broken atm

current master works as expected

[claudeleveille]

Yeah it started failing for every new project in my CI pipelines. Curiously, my existing project still builds fine even though it uses packages that I was trying to download in new projects. Maybe because the lock file already existed for the projects prior to the failure.

[claudeleveille]

I still get the TypeError even after upgrading to 2018.10.9.

[claudeleveille]

It seems to be working like normal again, just... like that. Version 2018.10.9. Well, seems like this wasn't ONLY pipenv's fault. Given it's now resolved, I'll close this issue.
