问题
I have two questions.
First, how can I find out what Python modules (and their versions) come with Mac OS-X 10.6.8 Snow Leopard?
Second, what is the deal with Snow Leopard and Tix? I absolutely cannot understand this. If I import Tix, no errors. If I interactively type
>>> help(Tix)
I get megabytes of info on using Tix. If I go any further this happens...
>>> root = Tix.Tk()
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/System/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/lib-tk/Tix.py", line 210, in __init__
_tkinter.TclError: can't find package Tix
>>>
Oh, the widow will open but I still get the error. I click the window and notice the menu bar said, "Python". Under, "File" I see, "Run Widget Demo". I start it up and every Tix demo runs. When I click the demo's, "See code" I see it's all in (what I assume to be) Tcl.
Tcl/Tk is version 8.5x, Tix is installed and I can import it with Python but I can't use it?
回答1:
Mac OS X 10.6 comes with Python 2.6.1.
The TKinter version on that platform is Apple 8.5.7 and has known problems; IDLE won't run with it, for example.
See the IDLE and tkinter with Tcl/Tk on Mac OS X page on Python.org for more details.
Terminal output for help('modules') on a 10.6 machine:
$ sw_vers -productVersion
10.6.8
$ /usr/bin/python
Python 2.6.1 (r261:67515, Jun 24 2010, 21:47:49)
[GCC 4.2.1 (Apple Inc. build 5646)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> help('modules')
Please wait a moment while I gather a list of all available modules...

Enter any module name to get more help. Or, type "modules spam" to search
for modules whose descriptions contain the word "spam".
The pygame and vboxapi (VBoxPython2_5, VBoxPython2_6, vboxapi, vboxshell) packages are non-default add-ons installed later on that machine, the rest should be standard issue.
