Resolve ci exception log on py37 - #362

Can the version consider Python 2?

I wonder if pylint 2 claims errors which might break Python 2, but good for Python 3.

I can't say it won't happen.
Your point is that we should have the same pylint version for python2/3, right?

Since exception log is no impact to the results, we can upgrade those version when we drop python2 support in the future.

Yes.
We support both of them by one codebase.

btw, we have https://github.com/appium/python-client/blob/master/development.txt .
It refers to ci-requirements.txt. we should update here, too.
