install Rodeo on OS X El Captain

Today I try to install Rodeo in order to use python for data analysis on my macbook. It is a new macbook (and the New Macbook) so I started everything from scratch. I installed Anaconda as recommended and then I installed iPython notebook. Everything worked fine.

Then I tried to start Rodeo, hmm, error message: "Bad news. Rodeo cannot start".

What can I do? I searched on the internet but found nothing. I can use both ipython and python from my terminal so I thought that could not be a problem. Then I made a guess - there must be something wrong with environment variables. I tried to echo my environment variables from the terminal:

It looks fine to me. Then I opened Rodeo again,  discarded the error message,  and opened its preference tab. Wait, I can specify the python I want to use here, and by default it is /user/bin/python! So I tried this python,

Apparently, my macbook somehow comes with python 2.7. I changed the python path in Rodeo's preferences tab to /Users/Liyun/anaconda/bin/python and restarted Rodeo. This time it worked perfectly. Well, I guess for whatever reason Rodeo is trying to use the old python although I have installed Anaconda for it.
