从MacPorts运行Python 2.7时出现MAXREPEAT问题

我在MacPorts上运行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

当我将

python27

设置为活动状态（如上所述）时，在运行

python

时会出现以下错误：

$ 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()

    known_paths = addusersitepackages(known_paths)

    user_site = 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')

    from _sre import MAXREPEAT
ImportError: cannot import name MAXREPEAT

我在运行

python2.7

时没有出现上述错误，只有在shell中运行

python

时才会出现上述错误

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

$ which python
/opt/local/bin/python

有什么建议吗

谢谢。

我也有同样的问题。指向可执行文件的链接似乎有问题，尤其是vim/MacVim。经过讨论，我自己解决了这个问题

还有更多的材料

希望这有帮助

我刚刚经历了同样的问题。快速简便的解决方法是在~/.profile中添加别名：

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terminal实例，python应该可以正常工作，没有错误

alias python='python2.7'
