在an zhuang guo ch安装过程中，报错

但是colleciton.abc不是python3才支持的吗？

也许应该调整下 swagger_py_codegen 的版本？

I had same issue... as a hacky fix I changed the import statement in Curve/venv/lib/python2.7/site-packages/dpath/util.py
from

from collections.abc import MutableMapping
from collections.abc import MutableSequence

to

try:
    from collections.abc import MutableMapping
    from collections.abc import MutableSequence
except ImportError:
    from collections import MutableMapping
    from collections import MutableSequence

and it seems to work.

I've submitted a pull request, adding dpath==1.5.0 as an explicit requirement.
