Hi, I'm on mac and looking to use SublimeREPL with python 3.3 version there.
Right now I have 2.7.

My os version is 10.8

Thanks!

Create python3 virtualenv in one of the directories scanned by SublimeREPL, and use 'Python: virtualenv' REPL.

PS.
in your virtualenv do pip install IPython pyzmq to enable IPython goodness in SublimeREPL.

If you don't want to use virtualenv, create Packages/User/SublimeREPL/config/Python/Main.sublime-menu with the following contents:

You'll need to modify the path to python3 if you're not using MacPorts. I'm of two minds about virtualenvs - on the one hand they're great for creating perfectly customized environments, testing different versions of modules, etc., but on the other hand I like just having one single environment with all of my packages available. The choice is up to you :)

Thanks very much for your help. Trying this on OS X El Capitan with Sublime Text 3 and Python 3.5. I presume the Path is /Library/Frameworks/Python.framework/Versions/3.5/bin. I replace the
'cmd': ['/opt/local/bin/python3', '-i', '-u'],
with
'cmd': ['//Library/Frameworks/Python.framework/Versions/3.5/bin', '-i', '-u']
then error:
PermissionError(13, 'Permission denied')
should I chmod anything? Or should I have sudo'd something I haven't?

@harri00413 you forgot to add the python3 executable on to the end of it:

Thanks, that worked. Now I only need to make a quick link or so to run the current module.

Thanks a lot, I try it, easy to use.

if you have installed python3 on your mac, just replace 'cmd': ['python', '-i', '-u'], with 'cmd': ['python3', '-i', '-u'],

if you have installed python3 and SublimeREPL, you can try setting up key bindings with the correct path to the python3 file.

You can try by copying this code into your /Sublime Text 3/Preferences/Key Bindings/

Hope this helps!
