Pika is not compatible with python 3.7

[aolefira]

"async and await are not recommended to be used as variable, class, function or module names. Introduced by PEP 492 in Python 3.5, they will become proper keywords in Python 3.7." https://docs.python.org/3.7/whatsnew/3.5.html#new-keywords

So, you catch error in python 3.7:
/envs/plarin-3.7.0a4/lib/python3.7/site-packages/pika/adapters/libev_connection.py", line 106
self.async = None
^
SyntaxError: invalid syntax

We would be glad to accept a PR to address this, thanks!

Had the same using python 3.9. Just downgraded to 3.6 (into my venv) and worked fine.

@clarabez could you provide more detail? Specifically, what errors? I just ran the test suite successfully using Python 3.9.1 -

@meaditisharma this was fixed in #924. Please upgrade Pika.
