@galaunay, thank you for working on this. Two other related issues that this PR may have closed by now (or that this work will close) are #231 and #1449.

If rope is no longer being used by elpy do the other references to rope in the codebase need cleaning up?

[sten0]

@doolio, if you have time to take a look at #1865 I would be very grateful. In particular, the PosixPath change in Jedi and Parso seems like it should be higher priority than a Rope cleanup.

Sorry sten0, I'm not going to be much help here. I'm only a beginner self-taught programmer. Wish you luck in resolving your issue.
