Python pylint requires Python '>=3.4.*' but the running Python is 2.7.12

用pylint 1.9.x 安装

 pip install pylint==1.9.3.

或者换源

pip install -i https://pypi.tuna.tsinghua.edu.cn/simple --upgrade pylint==1.9.3 

应该是可以安装成功

下面是stackoverflow上的问答

pylint still maintains support for Python 2 until maybe next year or so. But you need to install 1.9.X instead of 2.X. It seems though that you already had pylint installed, once you uninstall it you should be able to get 1.9 instead

And we can use this command to install the last pylint version of 1.9.x for python2.7.

pip install pylint==1.9.3.
