spyder3 missing rope dependency

[kamaraju kusumanchi <raju.mailinglists@gmail.com>]

Launching spyder3 gives the following error

You have missing dependencies!
rope >=0.9.4: None (NOK)
Please install them to avoid this message.

I see a python-rope package but no analogous python3-rope. Any idea
how to fix this?
