Failed calling sys.__interactivehook__
Traceback (most recent call last):

for line in open(filename, 'r'):
UnicodeDecodeError: 'gbk' codec can't decode byte 0x80 in position 247: illegal multibyte sequence

解决方案：

方法1：卸载pyreadline模块（我用的第二种）

方法2：把site-packages目录下的pyreadline目录删除（解决了）

 

原因：BUG，但是具体是什么样子的BUG还在找。
