`:IPython` crashes with `ImportError: cannot import name urandom`

hmm, seems like an issue with the python used by your vim. I think it is incomplete or wasn't built properly, since according to that traceback, just doing :py from random import Random or :py import tempfile would fail - and neither of those involve IPython or vim-ipython. So I think you'll have to fix that Cellar installation, or compile vim to have it grab the working python installation.

I have the same error on one of my pcs v a brew installed python. Should we raise a ticket with the python people?

I had exactly the same error using Enthought IPython.

I lodged this ticket with the python people: Homebrew/legacy-homebrew#18204

[i also posted this at the python issues tracker]

I checked my python sys.path against my vim sys.path and found that the two differed by a single line. The vim sys.path also contained this line:

/usr/local/Cellar/python/2.7.3/Frameworks/Python.framework/Versions/2.7/Extras/lib/python

I also checked against my laptop, which has a fully working of both, and is supposed to be the template for the desktop install, and this line does not appear. Interestingly, one that does is /Users/mcooganj

Could this be the problem? If so, how does one edit the sys.path?

[mcooganj]

Okay, i got it sorted: the problem is with the macvim build (or at least that was the source of my problem). You can tell as :py from random import Random threw (basically) the same error.

the fix:

$ brew unlink python

$ brew unlink macvim

$ brew remove macvim

$ brew install -v --force macvim

$ brew link macvim

$ brew link python

glad to hear it all worked out, @mcooganj, hopefully @rouge8 also go a fix in? closing for now, feel free to reopen if you still think this is an issue with vim-ipython
