Question

I am attempting to install and run iruby . I run iruby in the terminal with iruby but I receive:

iruby notebook

I have installed ipython ( I have installed Anaconda, but when i

run conda update conda

and

conda update ipython

but says:

command not found: conda

Is this an iruby program issue?

Reposting as an answer:

The trouble was that the Anaconda .../bin directory was not on $PATH , so the commands ipython and conda could not be found.

To fix this: Look for a file in your home directory called something like .profile or .bash_profile . These are hidden by default, so you may have to do something extra to see them. Add a line to the file you find like PATH="$HOME/anaconda/bin:$PATH" . Then close your terminal and reopen it, and you should be able to run ipython and conda. You can use the command echo $PATH to see the contents of PATH.
