Unable to run Anaconda on Mac 10.11

Question

In this tutorial (3.16), after downloading and then running graphical installer from from main anaconda website and then typing on mac's terminal:

$ python
Python 3.5.2 |Anaconda 4.1.1 (x86_64)|...

However, when I do the same thing, it gives me the following:

JOHNMAC:~ Main$ python
Python 2.7.13 (default, Apr  4 2017, 08:46:44) 
[GCC 4.2.1 Compatible Apple LLVM 8.0.0 (clang-800.0.42.1)] on darwin
Type "help", "copyright", "credits" or "license" for more 
information.

1. Why not python version 3?
2. Is it actually running Anaconda? It's not displaying Anaconda version like my tutorial's computer does...

For more info...

JOHNMAC:~ Main$ python3
Python 3.6.1 (v3.6.1:69c0db5050, Mar 21 2017, 01:21:04) 
[GCC 4.2.1 (Apple Inc. build 5666) (dot 3)] on darwin
Type "help", "copyright", "credits" or "license" for more information.

Checking $PATH:

JOHNMAC:~ Main$ echo $PATH
/usr/local/bin:/usr/local/sbin:/Users/Main/anaconda/bin:/Library/Frameworks/Python.framework/Versions/3.6/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin

Answer 1

Try typing which python to see where the python binary is coming from.

Because Unix looks up binaries in PATH order, it will check for python in /usr/local/bin first, and use the preinstalled python instead of the python installed by Anaconda at /Users/Main/anaconda/bin/python .

To fix this, you can change your PATH order by running:

export PATH=/Users/Main/anaconda/bin:/usr/local/bin:/usr/local/sbin:/Library/Frameworks/Python.framework/Versions/3.6/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin
