Hi, I just wanted to note that the instructions have us download the installer from the Hello World! book, but are missing an important step which may affect some users: On OSX 10.9.1 Mavericks, with Apple's version of Python 2.7.5 pre-installed, the 'Hello World!' installer appears to install python.org's version of Python 2.7.5 into the 'Applications' directory. However, the installer does not automatically run '/Applications/Python 2.7/Update Shell Profile.command'. This leaves Apple's python2.7 (/usr/bin/python2.7) as the default rather than python.org's python2.7 (/Library/Frameworks/Python.framework/Versions/2.7/bin/python2.7). As a result, the necessary site-packages such as 'pygame' and 'PyQt4' cannot be found: $ which python /usr/bin/python $ python -c 'import site; print site.getsitepackages()' ['/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python', '/Library/Python/2.7/site-packages'] $ python -c 'import pygame; import PyQt4' Traceback (most recent call last): File "", line 1, in ImportError: No module named pygame The solution is to manually run 'Update Shell Profile.command', after which things will work as expected: $ which python /Library/Frameworks/Python.framework/Versions/2.7/bin/python $ python -c 'import site; print site.getsitepackages()' ['/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages', '/Library/Frameworks/Python.framework/Versions/2.7/lib/site-python', '/Library/Python/2.7/site-packages'] $ python -c 'import pygame; import PyQt4'
