python显示语言错误_python语言环境奇怪错误。到底怎么回事？

所以今天我升级到了bazaar 2.0.2，我开始收到这条消息(顺便说一句，我在玩雪豹游戏)：bzr: warning: unknown locale: UTF-8

Could not determine what text encoding to use.

This error usually means your Python interpreter

doesn't support the locale set by $LANG (en_US.UTF-8)

Continuing with ascii encoding.

很奇怪，因为我的郎酒实际上是空的。当我尝试修改locale模块时，也会发生类似的事情Python 2.5.4 (r254:67916, Nov 30 2009, 14:09:22)

[GCC 4.3.4] on darwin

Type "help", "copyright", "credits" or "license" for more information.

>>> import locale

>>> locale.getdefaultlocale()

Traceback (most recent call last):

File "", line 1, in

return _parse_localename(localename)

File "/Users/sbo/runtimes/lib/python2.5/locale.py", line 375, in _parse_localename

raise ValueError, 'unknown locale: %s' % localename

ValueError: unknown locale: UTF-8

输出语言没有帮助sbo@dhcp-045:~ $ export LANG=en_US.UTF-8

然而，这解决了问题sbo@dhcp-045:~ $ export LANG=en_US.UTF-8

sbo@dhcp-045:~ $ export LC_ALL=en_US.UTF-8

('en_US', 'UTF8')

你能解释一下这是怎么回事吗，为了更好地粘在一起？
