Question

我已经使用macports安装了python（以及来自macports的一些其他python包）。与macports一起安装的python可执行文件位于/opt/local/bin/python-2.7，而mac附带的可执行文件是/Library/Frameworks/Python.framework/Versions/2.7/bin/python。

如何切换到安装了macports的版本？

Answer 1

使用port select命令：

$ port select --list python
Available versions for python:
    none
    python25-apple
    python26-apple
    python27 (active)
    python27-apple
    python33
    python34

$ python
Python 2.7.8 (default, Jul  5 2014, 20:17:23)
[GCC 4.2.1 Compatible Apple Clang 4.0 ((tags/Apple/clang-421.0.60))] on darwin
Type "help", "copyright", "credits" or "license" for more information.

$ sudo port select --set python python34
Password:
Selecting 'python34' for 'python' succeeded. 'python34' is now active.
