UnicodeDecodeError: 'utf8' codec can't decode byte 0xcc in position 0: invalid continuation byte

windows python2.7 执行 pip -h 然后报错如何，怎么破？
$ pip -h

看起来很怪啊， 你可以看下他那个 pip-script 的脚本， 为什么 help 会涉及 simpleHTTPserver 。。。

codec 这个问题，一般就是因为他以为他在 Decode UTF-8 的数据，但是实际上他不是 UTF-8 的

[mingyun]

@matthewgao 那个文件就 10 行代码
#!d:\python2\python.exe
# EASY-INSTALL-ENTRY-SCRIPT: 'pip==1.5.2','console_scripts','pip'
__requires__ = 'pip==1.5.2'
import sys
from pkg_resources import load_entry_point

if __name__ == '__main__':
sys.exit (
load_entry_point ('pip==1.5.2', 'console_scripts', 'pip')()
)

和这个有关吗？
>>> sys.getdefaultencoding ()
'utf-8'

[xiazi]

这样的情况一般都是 gbk 被当成 utf-8 decode 了.

应该使用:
import locale
locale.getdefaultlocale ()[1]

[mingyun]

@xiazi locale.getdefaultlocale ()[1]输出 cp936 该怎么处理呢？

[xiazi]

升级到 python2.7.10
