    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

    @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'

    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]

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