Check Python 3 source with Pylint running with Python 2

Question

Some checks of Pylint are depending on whether the checked source code is of kind Python 2 or Python 3. E.g., see How to avoid Pylint warnings for constructor of inherited class in Python 3?.

In my setup I run Pylint on a development server, which is using Python 2.7. However, I use Pylint to automatically check Python 3 code on each commit.

How can I configure Pylint to perform checking for Python 3, even if it runs under Python 2?

Answer 1

Short answer: you can't.

Pylint is using the builtin Python parser, and also get standard library information on demand, so the Python version running Pylint has a high impact on its output.

You should have several Pylint installations if you want to use it to check both Python 2 and Python 3 code.

Answer 2

You can install pylint using pip3

sudo apt-get install python3-pip
sudo pip3 install pylint
