How to run Pylint with PyCharm

You can set up Pylint to work with PyCharm by following the following 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%\Programs\Python\Python36-32\Scripts\pylint.exe # Possible location Open the PyCharm settings window with menu File → Settings, then navigate to menu Tools → External Tools in the sidebar. (Or search "external tools") Set up an external tool by clicking on the + sign and filling in the fields accordingly. In Program use the path you got when running which pylint. For the other values, you can use the same from the image. Run pylint from menu Tools → External Tools → pylint: Look at your output in the PyCharm terminal

For more details, refer to Pylinting with PyCharm.

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 activate External Tools → pylint as shown below.

Because I didn't find a working ready-made setup, these are the settings I use in PyCharm CE 2018.1 on macOS:

1 - pip install pylint in your project virtualenv or globally

2 - Add new external tool and configure:

Program: pylint
Arguments: "--msg-template='{abspath}:{line:5d},{column:2d}: {msg} ({symbol})'" --output-format=colorized "$FilePath$"
Working directory: $ProjectFileDir$
Output filters: $FILE_PATH$:\s*$LINE$\,\s*$COLUMN$:

Notice the required double quotes for the msg-template, and the escape chars for the output filters. The output filter allows to click on the file path and open the location in the IDE source editor.

Only missing feature would be the output filters to plot the lint descriptions directly into the source view, as is done with the builtin linter. No such feature at this time though.

You can try this Pylint PyCharm plugin:

It provides both real-time and on-demand scanning of Python files with Pylint from within PyCharm/IntelliJ IDEA.

Once you have it installed, the real-time inspection works automatically. For the on-demand you have several options that go from just checking the current open file to scan the entire project:

(Just for the sake of transparency, I am the developer.)

I now use and recommend the PyCharm plugin which didn't exist when I first wrote this answer.**

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 menu Tools* → External Tools → PyLintPyCharm. Each line of output will be hyperlinked to the relevant position in the source code.

A note on the previous answers. I was searching for a method to make PyCharm aware of the output syntax so I can directly jump to the file locations. That works without using additional tools.

Pylint can be configured to output messages in a specific format using the msg-template option in the pylintrc file or the CLI option --msg-template.

I set it to: msg-template='{abspath}:{line}:{column}: {msg_id} {msg}'

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.

Roberto Leinardi has created a Pylint plugin for PyCharm which really works and integrates well into the IDE:

Easy to install from the repositories, full instructions under:

pylint-pycharm

I have a short, yet a happy, experience with it so far! Kudos to Roberto.

Thanks to information here, and updated documentation from PyCharm, I've been able to get this to work nicely to also use the virtual environment for the project (ensuring that any packages can be deployed within the virtual environment and do not need to be deployed globally).

Taking what lkraider provided earlier, but with slight modifications:

Ensure you install Pylint within the virtual environment. Note, make sure that when you created the virtual environment you did not select "Inherit global site-packages". If you do then Pylint will end up being globally and this will not work. Add a new external tool and configure. This is slightly different compared to what lkraider provided. For one I wanted it to look more like normal Pylint output, hence my msg-template (and Output filter) is a bit different. Each to their own. The second change is the more critical one for executing Pylint based on the virtual environment. That is the program parameter where I use $PyInterpreterDirectory$. Program: $PyInterpreterDirectory$/pylint Arguments: "--msg-template='{abspath}:{line:5d}:{column}: {msg_id}: {msg} ({symbol})'" --output-format=colorized "$FilePath$" Working directory: $ProjectFileDir$ Output filters: $FILE_PATH$:\s*$LINE$\:\s*$COLUMN$:
