How to run Pylint with PyCharm

 

I want to configure pylint as an external tool on my entire project directory for a python project that I'm working on. I've tried to use the repository as a module with __init__.py and without, and its not working either way.

I'm having difficulty setting up pylint to run with PyCharm. I know that I should be running it as an external tool, however the settings confuse me.

The authoritative source on their documentation is broken, so I can't check that up either.

You can set up pylint to work with PyCharm by following the next steps:

  • Install pylint : 

    $ pip install pylint

  • Locate your pylint installation folder: 

    $ which pylint         # MacOS/Linux
/usr/local/bin/pylint  # this is just a possible output check yours


    $ where pylint         # Windows
%LocalAppData%ProgramsPythonPython36-32Scriptspylint.exe  # possible location

  • Open the PyCharm settings window with File -> Settings , then navigate to Tools -> External Tools in the sidebar. (Or search "external tools")

  • Setup an external tool by clicking on the + sign and filling the fields accordingly. In Program use the path you got when running which pylint , for the other values you can use the same of the image.

  • Run pylint from Tools -> External Tools -> pylint :

  • Look your output in the PyCharm terminal

    • For more details, refer to Pylinting with PyCharm.

    Update:

    If you want to use pylint to check your whole project or a particular file or directory, you can right click on your project root, file or directory, then External Tools -> pylint as shown below.

    At first install pylint with pip: 

    pip install pylint

    You have to open “Settings > Tools > External Tools” and press the “+” button at PyCharm.

    Here are an example with good settings.

    A colleague pointed me towards pylint-pycharm on GitHub. It's a wrapper around pylint with output formatted for PyCharm. Here's how I set it up: 

    git clone https://github.com/perses76/pylint-pycharm.git
cd pylint-pycharm
python setup.py build

    This creates build/scripts-2.7/pylint-pycharm

    Then, in PyCharm, create a new External Tool with these settings: 

    Program: path to your installation of pylint-pycharm  
Arguments: --virtualenv=$PyInterpreterDirectory$/.. $FileName$
Working directory: $FileDir$ 
Output filters: $FILE_PATH$:$LINE$:$COLUMN$:.*

    Now run it from Tools -> External Tools -> PyLintPyCharm. Each line of output will be hyperlinked to the relevant position in the source code.
