FileNotFoundError

[aisen0921]

My system is windows 10, sublime 4169, when I save file the console out show
`Traceback (most recent call last):
File "./python3.3/subprocess.py", line 1104, in _execute_child
FileNotFoundError: [WinError 2] 系統找不到指定的檔案。

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
File "C:\Program Files\Sublime Text\Lib\python33\sublime_plugin.py", line 1499, in run_
return self.run(edit)
