ipython on MacOS 10.10 - command not found

Question

I'm trying to get ipython working in Mac OS 10.10.

problem:

$ ipython

returns

-bash: ipython: command not found

context:

I'm running python2.7 on MacOS 10.10. I installed python via brew. Some info:

which python =

/usr/local/bin/python

brew info python =

python: stable 2.7.10 (bottled), HEAD
Interpreted, interactive, object-oriented programming language
https://www.python.org
/usr/local/Cellar/python/2.7.10_2 (4977 files, 77M) *

To install ipython I ran

pip install ipython[all]

so... pip show ipython =

Can anyone tell me what I'm doing wrong?

Answer 1

I met the same issue but resolved. You need to make sure install IPython at first via this command on terminal.

$python -m IPython

Then it will show this result:

Congratulations! You had IPython in your computer.

Then run this command on terminal.

alias ipython='python -m IPython'

Finally you can try ipython command again.

You can add this command line into ~/.bash_profile file for permanent. It works fine for me.

Answer 2

I was trying to install jupyter with 'pip install jupyter'. http://jupyter.readthedocs.org/en/latest/install.html

Then I got similar error on running ipython. I did try all solutions on Stackoverflow about installing ipython.

At last, I installed Anaconda then run conda install jupyter. Now everything works fine.

My environment:

1. Python 2.7
2. Mac OS X El Capitan
