Versions: Sublime Text 3, sublimeREPL 2.1.1, ipython 2.3.1, python 2.7.9, using OSX Yosemite
When I try to open an ipython interpreter through sublimeREPL, I get a regular python interpreter. No warnings or error messages.
If I navigate to /Users/username/Library/Application Support/Sublime Text 3/Packages/SublimeREPL/config/Python and type python -u ipy_repl.py then it does indeed open an ipython interpreter. It seems like the the wrong command is being executed, not sure why.
