Python出现了一个异常卡在那里不动了

Question

我是在win8上面操作，运行一个Python项目
Python：2.7

node：0.12

npm：2.11

vs：2012

输入run all（这个是自己定义的命令，用于启动项目） 后出现：

2015-08-25 22:13:47 [24784] [WARNING] Your terminal is not configured to receive
UTF-8 encoded text. Please adjust your locale settings or force UTF-8 output by

Traceback (most recent call last):

   prepare(preparation_data)
 File "C:\Python27\Lib\multiprocessing\forking.py", line 488, in prepare
   assert main_name not in sys.modules, main_name
AssertionError: __main__

然后就一直卡在这里，
请各位老师指点一下，已经困扰好几天了，不胜感激
