Question

I try to set autoreload to my development process, but it seems, that the method I learned from that thread is not working with my versions.
I tried

1. ipython -V: 0.10 and python -V Python 2.6.6
2. ipython -V: 0.10.1 and python -V Python 2.7.3

but

%load_ext autoreload
%autoreload 2

returns

ERROR: Magic function `load_ext` not found.

which is kind of obvious, because

In [1]: %lsmagic
Available magic functions:
%Exit  %Pprint  %Quit  %alias  %autocall  %autoindent  %automagic  %bg  %bookmark  %cd          %clear  %color_info  %colors  %cpaste  %debug  %dhist  %dirs  %doctest_mode  %ed  %edit  %env      %exit  %hist  %history  %logoff  %logon  %logstart  %logstate  %logstop  %lsmagic  %macro  %magic  %p  %page  %paste  %pdb  %pdef  %pdoc  %pfile  %pinfo  %popd  %profile  %prun  %psearch  %psource  %pushd  %pwd  %pycat  %quickref  %quit  %r  %rehash  %rehashx  %rep  %reset  %run  %runlog  %save  %sc  %store  %sx  %system_verbose  %time  %timeit  %unalias  %upgrade  %who  %who_ls  %whos  %xmode

this method is not available. How can I install other magic functions?

Answer 1

Current Install

In your current install, can you try:-

import ipy_autoreload

and see what you get?

New Install

Can you attempt to reinstall IPython with

pip install ipython

(for a local install if you are using virtualenv) or

sudo pip install ipython

if you are install your IPython system-wide.

And because pip install doesn’t deal with sys path properly if you are on Mac OSX, you might need to do

easy_install -a readline   # `sudo easy_install -a readline` for system-wide install of course.

(if you are using Mac OSX)

If you have the latest IPython, you should see IPython 0.13.1 when you first load up the shell. And you shouldn’t have any problems with %load_ext autoreload then.
