WARNING: You are using pip version 20.1; however, version 20.1.1 is available.
You should consider upgrading via the '/usr/bin/python3 -m pip install --upgrade pip' command.

The error comes from /usr/local/lib/python3.7/dist-packages/typing.py which is not part of the stdlib. Do you have the typing package intalled? If yes, uninstalling it should be fine as typing is part of the stdlib since 3.5.

Also worth noting: https://stackoverflow.com/q/55833509/2650249. Looks like this is not related to xmlsec, thus closing. Ping me if this issue should be reopened, though!

Happens on 3.8 also

Looks like its related to pip [1, 2]

pip install -U "pip<20.1"

pip3.7 install -U --user "pip<20.1"

pip3.8 install -U --user "pip<20.1"

Then I had to remove and recreate virtualenv for the project I was on
