Python 3.0 - Idle wont open. He just bounces in the dock

Question

Python / Unix noob. On Mac OSX

Launched Python 2.7.2 for several weeks along with the Idle application. No problems.

Today I just installed Python3.0 along side 2.7 - I tested both and can still be run via Terminal.

Now when I open Idle for 2.7, it opens just fine. But when I open a new Idle application in the Python3.0 folder, the application just bounces in the document and never opens.

Error in console:

12/2/11 11:57:13.612 PM com.apple.launchd.peruser.501: ([0x0-0x38038].org.python.IDLE[313]) posix_spawn("/Applications/Python-3.0/Mac/IDLE/IDLE.app/Contents/MacOS/IDLE", ...): No such file or directory 

How can I open Idle for Python3.0?

Answer 1

Do not use Python 3.0. The initial releases of Python 3 were somewhat experimental and had a number of serious issues that were fixed in subsequent releases. Fixed issues include the one you see that I think was covered by Issue5196 . The current version of Python 3 is 3.2.2 and is considered ready for production. Here you can find installers for Mac OS X here . Depending on the version of OS X you are using, you install two installers. If on OS X 10.6 (Snow Leopard) or 10.7 (Lion), pay special attention to the warnings here about installing the current version of ActiveState Tcl / Tk, which will be used instead of the erroneous Tcl / Tk 8.5 supplied by Apple on these systems.
