Crash in virtual env on Windows 10, in powershell

[KennethNielsen]

Dear watson devs

I just tried installing watson inside a virtual environment on 10 in powershell. The virtual env was freshly created and the only thing I did with it was to activate it and install watson. After installation, when trying to call watson I get the following traceback:

Traceback (most recent call last):

It seems the problem is that a click type is instantiated with some bad arguments. I can do some more troubleshooting to try and figure out what it is called with, but I was curious whether anyone had any ideas.

According to #430, there is some kind of issue with click version 8. I fixed it (on linux) by downgrading click to 7.1.2, but there also seems to be a fix implemented in #432 (basically, multiple=True needs to be removed from several click options).

I can confirm that it's more or less related to #430...
