# Revision history [back]

Folks, I've had a similar problem. Downloaded the Sage.app, tried launching it, then (as suggested here) tried launching from the command line. Here are the results:

209 $/Applications/Sage-4.7.1-OSX-64bit-10.6.app/Contents/Resources/sage/sage ---------------------------------------------------------------------- | Sage Version 4.7.1, Release Date: 2011-08-11 | | Type notebook() for the GUI, and license() for information. | ---------------------------------------------------------------------- Traceback (most recent call last): File "/Volumes/sage-4.7.1-OSX-64bit-10.6-x86_64-Darwin/Sage-4.7.1-OSX-64bit-10.6.app/Contents/Resources/sage//local/bin/sage-ipython", line 18, in <module> import IPython ImportError: No module named IPython 210$

iPython is installed in my normal Python world.
