TypeError with pip 10.0.1

I am using Python 3.6.6 with pip 10.0.1 on Manjaro Linux. Trying to run the usual sudo pip-review -i command throws an error:

Exception:

Seems like it is an issue with bundling pip as in pypa/pip#5429 - unfortunately missed this before. Therefore I am going to close this issue.

Edit: The solution from #60 fixed this.
