我在从 MacPorts 运行 python2.7 时遇到了一些问题。

以下是可用 Python 版本的列表：

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

当我设置python27为活动时（如上），运行时出现以下错误python：

$ sudo port select --set python python27
Selecting 'python27' for 'python' succeeded. 'python27' is now active.
$ python
Traceback (most recent call last):
  File "/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site.py", line 548, in <module>
    main()
  File "/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site.py", line 530, in main
    known_paths = addusersitepackages(known_paths)
  File "/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site.py", line 266, in addusersitepackages
    user_site = getusersitepackages()
  File "/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site.py", line 241, in getusersitepackages
    user_base = getuserbase() # this will also set USER_BASE
  File "/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site.py", line 231, in getuserbase
    USER_BASE = get_config_var('userbase')
  File "/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/sysconfig.py", line 516, in get_config_var
    return get_config_vars().get(name)
  File "/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/sysconfig.py", line 449, in get_config_vars
    import re
  File "/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/re.py", line 105, in <module>
    import sre_compile
  File "/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/sre_compile.py", line 14, in <module>
    import sre_parse
  File "/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/sre_parse.py", line 17, in <module>
    from sre_constants import *
  File "/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/sre_constants.py", line 18, in <module>
    from _sre import MAXREPEAT
ImportError: cannot import name MAXREPEAT

我安装的端口版本是（根据sudo port installed）：

python27 @2.7.5_1
python27 @2.7.5_1+universal (active)

运行时没有出现上述错误python2.7，只有python在 shell 中运行时才会出现上述错误。

$ which python2.7
/opt/local/bin/python2.7

$ which python
/opt/local/bin/python

有什么建议么？

谢谢。

我刚刚遇到了同样的问题。一个快速简单的解决方法是在 ~/.profile 中添加一个别名：

alias python='python2.7'

如果您还没有 .profile 文件，只需创建一个。打开一个新的终端实例，python 应该可以正常工作，没有错误。

我有同样的问题。似乎是可执行文件链接的问题，尤其是 vim/MacVim。我按照这里的讨论为自己解决了这个问题。

这里还有更多的材料。

希望这可以帮助。
