Python-configrparse issues?

[Random User]

I am not sure if this is a python-configrparse issue or if it is something else.

I installed MITMf, owtf and a few other pyton scripts and I get these errors

Traceback (most recent call last):

Sorry for posting in the wrong area of the forums, Update: I have found this issue in a few other programs like mitmproxy & faraday.

Okay I figured it out something went wrong with pip

Fixed with : "easy_install -U setuptools" and then "pip install --upgrade setuptools"

Now all works again.
