Workaround is set PYTHONWARNINGS=ignore

Hm the solution is to get warnings to write to stderr...

Probably a cockpit error, but I'm still seeing this bug. Abbreviated summary form here, full details in the attached files:

The fix hasn’t been released so you’ll have to install from master. Can you confirm this is using the master branch?

[rdpoor]

The fix hasn’t been released so you’ll have to install from master.

That's almost certainly the problem. I assumed that since the version on my machine had a version later than when you closed this bug that I had the latest:

PS E:\github\SmartCableSensors> pipenv --version
pipenv, version 2018.11.26

I'll install from master and try again. Note to my future self (and others that follow):

 > pip install git+https://github.com/pypa/pipenv.git
Successfully installed pipenv-2018.11.27.dev0

Thank you.

P.S.: Fun fact: I dropped a suggestion to the author of commitstrip and garnered a mention of pipenv there:

I did install from master but now when I run pipenv install --dev it throws other bunch of errors

I don't have Anaconda2 at all. All I have is Anaconda3
