python - ubuntu 导入错误 : cannot import name MAXREPEAT

Question

升级到 13.04 完全搞砸了我的系统。我在运行时遇到了这个问题

     ./manage.py runserver


Traceback (most recent call last):
File "./manage.py", line 8, in <module>
from django.core.management import execute_from_command_line
File "/home/rats/rats/local/lib/python2.7/site-packages/django/core/management

from sre_constants import *
File "/home/rats/rats/lib/python2.7/sre_constants.py", line 18, in <module>
from _sre import MAXREPEAT
ImportError: cannot import name MAXREPEAT

现实环境和虚拟环境都会发生这种情况。我尝试使用

删除 python

sudo apt-get remove python

遗憾的是它已经删除了所有内容。现在谷歌浏览器不显示任何字体。我正在寻找让事情恢复工作。需要帮助才能再次正确配置它。

如果您使用的是 virtualenvwrapper，那么您可以在现有的之上重新创建 virtualenv(当前没有事件环境):

mkvirtualenv <existing name>

应该从系统中提取最新(升级)的python版本并修复任何不匹配的错误。
