Thanks a lot for the report. I don't get that error just doing a pip install nb2plots into a fresh Python 2.7 virtualenv. IPython has set itself up so pip installs the earlier version on Python 2.7, by default. Do you have any idea why that isn't working in your case? Which Python version are you using? What pip version do you have?

[matthew-brett]

@arthurlogilab - did you have any luck working out how your install differs from a fresh virtualenv install?

This issue is kinda old but still … It might be caused by too old pip because pip < 9 cannot properly recognize which version of a package to pick up for your Python version. Try to update pip first via pip install -U pip
