I am using ipython on Mac OS 10.5 with python 2.5.1 (I would actually like to use ipython for 2.6.1, but it doesn't seem to be available?)
I installed ipython via easy_install. It works but is missing gnu readline (needed for nice searching of command line history with ctrl-R, etc.)
I found a blog post and other sources saying this could be fixed by
sudo easy_install -f http://ipython.scipy.org/dist/ readline
However, this leads to build errors in readline.c
, particularly undeclared functions like rl_compentry_func_t
and rl_catch_signals
.
Has anyone seen these errors? Is there another way to get ipython installed with readline?
To install ipython on Snow Leopard or Lion without using MacPorts, you can simply do:
sudo easy_install readline ipython
(Note that if you use the "pip" to install readline, then ipython won't see the readline library, not sure why).
Edit:
If you had ipython installed remove it with
sudo pip uninstall ipython
or
pip uninstall ipython #for virtualenvs
Then make sure you have installed readline first and reinstall iptyhon
pip install readline ipython
For some reasons, if readline wasn't present during the installation, it will install itself without support for readline or it use the default mac readline.
