Issue with loading SublimeREPL in Sublime Text 3 and Ipython shell

Question

I have been trying to fix this issue for a while, but I have not been able to resolve it. I use SublimeREPL with Sublime Text 3. Whenever I try and launch the Ipython shell from SublimeREPL, I get this error:

Traceback (most recent call last):
  File "/home/user/.config/sublime-text-3/Packages/SublimeREPL/config/Python/ipy_repl.py",  line 51, in <module>

The issue seems to be with this ZMGTerminalIPythonApp object in the application.py module. Ipython works just fine when I load it from the command line.

UPDATE: So I also tried to run the ipy_repl.py file directly from the command line. I was expecting it to fail, but it actually worked just fine. I did not get the error above. So it is not clear why when invoking SublimeREPL from ST3 I get the above error but when I invoke the SublimeREPL ipython shell from the command line, it all works fine.

Has anyone else been able to resolve this issue?

Okay I figured out the problem. It all had to do with my $PATH variable. I use the Anaconda package from Continuum.io for scientific python--great package btw. So Anaconda will update the $PATH variable so that its version of the python binaries comes first in the $PATH and hence is the one that pip acts against. I knew that Ipython did this with Anaconda, but not the python too. So when I was updating pyzmq with pip, that was updating the Anaconda distribution instead of the normal locally installed python install in /usr/bin/ ...

Interestingly, SublimeREPL was trying to invoke the REPL against the python install in /usr/bin/... instead of just following the normal $PATH variable reference to the Anaconda distribution. I am still not sure how that happened?

So anyway, when I used the easy_install package installer to upgrade pyzmq instead of pip, then this updated the python install in /usr/bin/... instead of the Anaconda version. That resolved the problem.

So now SublimeREPL is working.
