redebug's Issues

magic.open ERROR. AttributeError: 'module' object has no attribute 'open

Hi, I have trouble in running this project under Python2.7
user@user:~/git/redebug$ python redebug.py /home/user/xxx /home/user/xxx Traceback (most recent call last): File "redebug.py", line 65, in <module> common.magic_cookie = magic.open(magic.MAGIC_MIME) AttributeError: 'module' object has no attribute 'open'

I found that in my magic.py, there is no method named "magic.open", and I want to know how to fix this. Thanks
