Python/Unix noob. On Mac OSX.
Been running Python 2.7.2 for a few weeks, along with Idle app. No problems.
Today I just installed Python3.0 along side 2.7 – tested both and can still be ran via Terminal.
Now when I open Idle for 2.7, it opens just fine. But when I open the new Idle app within the Python3.0 folder, the app just bounces in the doc and never opens.
The error from Console is as follows:
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 do I get Idle to open for Python3.0?
Do not use Python 3.0. The initial releases of Python 3 were somewhat experimental and had a number of serious problems that have been fixed in subsequent releases. The fixed problems include the one you’re seeing which I believe was covered by Issue5196. The current release of Python 3 is 3.2.2 and is considered production-ready. You can find installers for Mac OS X here. There are two installers depending on which version of OS X you are running. If on OS X 10.6 (Snow Leopard) or 10.7 (Lion), pay particular attention to the cautions here about also installing the current version of ActiveState Tcl/Tk to be used instead of the buggy Tcl/Tk 8.5 shipped by Apple in those systems.
