为什么没有在Sublime Text 2中使用SASS Build？

Question

当我尝试构建scss文件时，没有任何反应。

Sublime Console中的错误消息：

Running sass --update C:\Users\Administrator\Dropbox\Open Server\html\print-service.loc\www\css\sourse.scss:C:\Users\Administrator\Dropbox\Open Server\html\print-service.loc\www\css/sourse.css
Traceback (most recent call last):
  File ".\sublime_plugin.py", line 337, in run_
  File ".\exec.py", line 154, in run
  File ".\exec.py", line 45, in __init__
UnicodeDecodeError: 'ascii' codec can't decode byte 0xc0 in position 919: ordinal not in range(128)

为什么会发生这种情况？
