Getting a `configparser.DuplicateOptionError` when calling nbconvert #9

Closed ocefpaf closed 8 years ago

ocefpaf commented 8 years ago

I am seeing a similar problem as https://github.com/jupyter/nbconvert/issues/298 but I am using the latest entrypoints 0.2.2. One can reproduce the error below by installing jupyter and compliance-checker together and then issuing: entrypoints.get_single('nbconvert.exporters', 'python').load()

Traceback (most recent call last):

Not sure how to fix that...

Looks like compliance_checker did something weird with entry points. Recent versions of pip refuse to install it. It was fixed in ioos/compliance-checker#279, but they haven't made a release yet.

pip refusing that is the right way to go. Thanks for the fast response @takluyver!
