在Mac OS X 10.5.8版上安装Python 3.1 [英] Install Python 3.1 on Mac OS X version 10.5.8

问题描述

我使用Windows.我编写了一个Python 3.1脚本，使用Mac的朋友想运行它，但是我们无法让Python 3.1在他的Mac上正常工作.我认为问题在于未安装Python 3.1框架.这正是我所做的事情，也是为什么我认为这是问题所在.

I use Windows. I wrote a Python 3.1 script that my Mac-using friend would like to run, but we can't get Python 3.1 to work right on his Mac. I think the problem is that the Python 3.1 framework is not being installed. Here's exactly what what I did and why I think this is the problem.

我从Python下载页面(

I downloaded Python 3.1.2 from the Python download page (this file). I opened the file, then opened "Python.mpkg". I proceeded with the install wizard, and I made sure to check the box to install "Shell profile updater" during the wizard. I went to "/Applications/Python 3.1" and double-clicked "Update Shell Profile.command".

接下来，我选择编写的python脚本，然后在菜单栏中选择文件"，获取信息". 在打开方式"下，我从"/Applications/Python 3.1"中选择了"PythonLauncher".然后，我单击全部更改"按钮.现在，我双击我的程序来运行它，但是它是由Python 2.5.1而不是Python 3.1运行的. (对此，我很确定，我编写了一个程序"print(sys.version)".)

Next I selected the python script I wrote and selected "File", "Get Info" in the menu bar. Under "Open With" I selected "PythonLauncher" from "/Applications/Python 3.1". I then clicked the "Change All" button. Now I double-clicked my program to run it, but it was run by Python 2.5.1 instead of Python 3.1. (I'm sure of this, I wrote a program to "print(sys.version)".)

所以现在我试图弄清楚为什么"/Applications/Python 3.1"中的"PythonLauncher"使用的是Python 2.5.1.我打开"PythonLauncher"，发现"Python脚本"的解释器为"/usr/bin/pythonw".因此，我转到"/usr/bin/"，发现"pythonw"是指向"/System/Library/Frameworks/Python.framework/Versions/2.5/bin/pythonw2.5"的别名.显然，这应该是3.1版.因此，我转到"/System/Library/Frameworks/Python.framework/Versions/"，发现仅有的子文件夹为"2.3"和"2.5". 3.1在哪里?

So now I tried to figure out why the "PythonLauncher" from "/Applications/Python 3.1" is using Python 2.5.1. I opened "PythonLauncher" and found that the interpreter for "Python Script" is "/usr/bin/pythonw". So I went to "/usr/bin/" and discovered that "pythonw" was an alias pointing to "/System/Library/Frameworks/Python.framework/Versions/2.5/bin/pythonw2.5". Obviously this should be version 3.1 instead. So I went to "/System/Library/Frameworks/Python.framework/Versions/" and discovered that the only sub-folders are "2.3" and "2.5". Where's 3.1?
