I've installed pythonloc on my macOS laptop, running Python 3.7 installed via homebrew:

$ python3 --version

$ pip3 list

But when I run piploc install, I get an error:

Thanks for filing this! I have not tested with python 3.7, but I imagine this is an easy fix. I’ll take a look when I get a chance. Which version of pip are you running?

[fredrikaverpil]

This was on pip 18.1, but I just updated to 19.0.2 and I get the same error there.

[vtnate]

I'm getting the same error today. Python 3.7.3, pip 19.0.3, in macos 10.14.

Any update on a fix for this?
