今天用Django搭建一个环境，在访问后台的时候感觉有点怪：

感觉后台页面的样式似乎没有被加载进来，于是单独打开某个样式结果浏览器提示：

A server error occurred.  Please contact the administrator.

命令行：

Traceback (most recent call last):

一看就知道就知道又是蛋疼的Python编码问题了，每次写Python项目，总要被编码问题折腾几下，这次也不例外。结果网上一搜，也没搜出解决方法，倒是相关错误有人给出页面顶部加上编码设置：

#encoding:utf8

这有点要命，django项目那么多文件怎么加？应该是配置里有，于是找到了相关信息并在settings.py里添加：

DEFAULT_CHARSET = 'utf-8'
FILE_CHARSET = 'utf-8'

结果还是没有解决问题，又看到有人建议用gb18030，只好把上面那两句改成

DEFAULT_CHARSET = 'gb18030'
FILE_CHARSET = 'gb18030'

问题仍旧没有解决，最后摸索了两个小时快接近崩溃边缘时，偶然我的一个设置居然把这痛苦编码问题给解决了，在manage.py添加：

reload = reload(sys) 
sys.setdefaultencoding('gb18030')

问题解决，打开css静态文件也正常响应内容了
