Thanks for the report. I'm wondering if when you do "pip list" if pyparsing version is not 2.4.7 but 3.x. If you are really using 2.4.7 then I wouldn't expect this error.

[jameswex]

What is the notebook environment you are seeing this failure in? Does restarting the kernel help?

[paulaceccon]

Not sure what you mean but I'm using jupyter notebook, with Python 3.9. And no, restarting it doesn't help. Thanks for the quick responses!

[jameswex]

Are you able to test with python 3.6 or 3.7? I haven't tried WIT in py 3.9 yet.

[queengooborg]

Came here after running into the same issue but in web2py. This issue seems to come from an incompatibility in httplib2. After upgrading to v0.20.2 of httplib2, I am no longer running into this problem.

Hope this helps!

Or by downgrading to 0.19.0. That also worked

[alishaneogi98]

Thanks This also work for me. By running this command only - pip install httplib2. This will automatically downgrade the pyparsing to 2.4.7 version.

pip install httplib2
