Python version problems

[AndreasAlbert]

The last working RTD build was here with commit 2e3c0b3

However, if I use that commits on lxplus, I still get the same error (see below). What is typed_ast and why are we installing it?

The problem is with pylint, which starting with version 2.0 does not support python 2.7 anymore (see e.g. here. pylint 1.8 and 1.9 should still do it,but those are not installable on pip?

Never mind, can install it pylint < 2.0. Not sure why setup.py ever tries to install 2.0...

[AndreasAlbert]

Okay, everything works out if I just manually do
pip install "pylint<2.0.0"
before installing hepdata_lib. I would have thought that I can get the setup.py to do this by adding "pylint<2.0.0" to install_requires. This doesn't seem to work.

@clelange Any idea?
