iPython installed but not found
Searching the web for "bash: ipython: command not found"
turns up several hits (including this SO question), but they're not particularly helpful. From the sound of it, you have IPython
, the Python package installed, but ipython
—the entry point (i.e., wrapper/launcher script) for it—is missing for whatever reason. To check whether this is the case, try running:
% python -m IPython
Python 2.7.9 (default, Feb 10 2015, 03:28:08)
Type "copyright", "credits" or "license" for more information.
IPython 4.0.0 -- An enhanced Interactive Python.
? -> Introduction and overview of IPython's features.
%quickref -> Quick reference.
help -> Python's own help system.
object? -> Details about 'object', use 'object??' for extra details.

If that brings up IPython, then you might try making a shell alias as the SO answer linked above suggests, i.e., put something like this in your shell's startup script: alias ipython='python -m IPython'
. Or, create the launcher script yourself. For me, it lives in /usr/local/bin/ipython
and contains the following:
#!/usr/local/opt/python/bin/python2.7
# -*- coding: utf-8 -*-
import re
import sys
from IPython import start_ipython
if __name__ == '__main__':
sys.argv[0] = re.sub(r'(-script\.pyw|\.exe)?$', '', sys.argv[0])
sys.exit(start_ipython())
Hope this helps. (If it does, please consider up-voting the other SO question as well...)
UPDATE: Here are some more possibly-relevant links:
- ipython: command not found on OSX
- https://github.com/pypa/pip/issues/426
The answer given by @evadeflow does the job, but there are several other packages installed with pip and it will be very uncomfortable to keep adding alias
for each of them.
A rather elegant way would be to add the path where these packages are installed to the $PATH
variable. In my case adding the following line in ~/.bashrc did the job:
export PATH=$PATH:/home/my_user_name/.local/bin
