请教一个pip install 出现报asciii码错误的问题。

系统版本：win8.1 x64
python版本:2.7.5
pip版本:pip-1.4.1
异常如下：

不知道是什么原因，以前pip是好使的。突然有一天我兴致冲冲地想用一下python就出现这个问题了。不止是安装sh,安装Django，安装任何包都出现这个问题安装不了，网上搜也搜不出答案，所以只好把问题贴在这求大神们指教。

@c19 谢谢你。玩python时间不长，以上是我的输出，应该是和这个帖子一样的问题吧。应该怎么破？

@burgleaf ***见stackoverflow被采纳答案。***
print尝试把unicode编码成环境编码。你得环境编码是GBK。windows?
Linux临时环境变量设置如下：
c19@acer:~$ export LANG=zh_CN.GBK
