For me it was due to an incompatibility with my version of httplib2 (see https://github.com/PAIR-code/what-if-tool/issues/185#issuecomment-1013971242).

I just ran:

$ pip3 list | grep http
httplib2 (0.19.1)
$ pip3 install httplib2
Collecting httplib2

And it worked.

I had the same issue when trying rasa train. The problem seems to be the later version of pyparsing module no longer has that attribute. Downgrading it works for me.

run:

pip install pyparsing==2.4.2

then:

rasa train
