Does ropevim work with Python 3?

[bderrett]

I have installed the rope_py3k package. When I try to install ropevim I get the error

As you can see, pip tries to install rope, rather than using rope_py3k. I suppose this means that ropevim is incompatible with Python 3? If this is the case, it should be specified in the documentation.

Exactly, https://github.com/python-rope/rope/issues/57

rope now installs on Python 3, though ropevim does not. I tried using 2to3 with no success. I would really like this, it would be one more nail on my IDE coffin. Any chance to support Py 3?

[mcepl]

Good point, and although https://github.com/python-rope/rope/issues/57 has not been resolved, it might very well soon be. However, unfortunately I have not enough time for dealing with ropevim. Any pull requests will be kindly welcomed, of course. (the same applies to https://github.com/python-rope/ropevim/issues/47 I am afraid, although the fix for that may lie in ropemode).

I don't feel up to the task, but will clone the repo and give it a try. Hopefully someone more knowledgeable will be able to do it.

Well, this makes ropevim useless on recent versions of Debian (which switched to compiling vim with Python 3 rather than Python 2 in September 2016).
