Reported in pylint repo: pylint-dev/pylint#1784

The suggested approach in pylint-dev/pylint#1784 (comment) is to just use astroid 1.5.3. This is already done, so there is little more we can do here.

Arch Linux already has official python-astroid 1.6.0 packages, which means Conan 0.30.3 cannot be packaged for this distro without conflicting official repos. Are there any contingency plans?

[memsharded]

I don't see how this can be fixed :(
It doesn't seem the pylint-astroid maintainers are willing to fix this at the moment. Any ideas?

[tivek]

According to pylint-dev/pylint#1790 upgrading to pylint 1.8 should help. My quick'n'dirty tests with pylint 1.8.1 and astroid 1.6.0 seem to be fine. Can you please check?

@tivek In Python3 too? I recall trying it in Win Py3 with Astroid 1.6.0 and the issue was still there.

[tivek]

Python 3.6.4, pylint 1.8.1, astroid 1.6.0 in a clean conda env, I don't get the pylint-dev/pylint#1790 bug. I will try to get TravisCI to run tests with pylint 1.8.1 and astroid 1.6.0.

Yay, TravisCI and AppVeyor pass the tests. If bumping pylint and astroid requirements is ok, hopefully this can get into Conan 1.0.
