opencanaryd --start启动报错

[zeroer71]

报错：
from ._compat import _AnnotationExtractor
File "/usr/lib/python2.7/site-packages/attr/_compat.py", line 11, in
from collections.abc import Mapping, Sequence # noqa
ImportError: No module named abc
查阅了资料，说Python2.7没有collections.abc这个库，但是项目又是用Python2.7起的，应该怎么解决呢

没事了，已解决，安装低版本twisted即可。

I am so sorry that I have been not solved some issues. In recently I have no time to care about this project.
