I want to configure Pylint as an external tool in 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 it's 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 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}'
In the External Tools settings, the Output filters: can be set to
$FILE_PATH$:$LINE$:$COLUMN$: .*
so PyCharm shows links to directly jump to the reported locations.
This can be combined with output-format=colorized so I get this:
PyCharm does not recognize the column despite having it configured. But having the file and line is enough for me.
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*$COLUMN$:
External tool for Pylint
I recently installed VScode on Ubuntu, and now it doesnt automatically linter the code using the python interpreter (as it did on Windows). This is really annoying me because I have to save the file every time I want it to linter.
Any answers are greatly appreciated
If you need more info, just let me know and I will provide it
By default, linting for Python is enabled in Visual Studio Code using Pylint, and you can enable other linters of your choice. You can easily enable and disable all linting by using the Python: Enable Linting command. Also you can verify your linting settings:
Go to Settings and check the which linting rules you have enabled :
Go to Command Palette and check if the linter is enabled:
More info: https://code.visualstudio.com/docs/python/linting
There is a setting called Python: Jedi Enabled(looks like this). If you switch if off and then restart VSCode, the issue should be fixed
Visual Studio Code by default has sensible pylint settings that limits the number of pylint messages that are output.
Is there any way to easily trigger a "pylint run" including the tests that are disabled by vscode by default either on all modules or on an individual module without messing with the vscode settings every time?
Unfortunately there isn't a way to temporarily flip the linting cap for just a single lint check.
I'm trying to integrate pylint with pyCharm, but I want it to be an online tool.
What do I mean ? I want it to detect errors and checking code standards when I write the code.
Until now, I have done it by clicking "Tools --> External Tools --> pylint".
There is an option to do this ? or maybe call the Pylint when I run the script ?
Thanks.
Under Run -> Edit Configurations... you can see the Configuration on the right Side. At the Bottom is a Section called Before launch: Activate tool window where you can hit the green plus Button and configure pylint to be executed before the run.
I am just going through this myself - I think there are some earlier answers about setting up an external tool to produce a report, but this exists and sounds like exactly what you want.
Pylint-Pycharm
Pylint-Pycharm is a wrapper around Pylint that formats file paths in the Pylint output in a way that Pycharm can parse. This allows you to go to finding directly by clicking on the provided link.
The tool accepts the directory of a virtual environment as parameter and requires the paths of one or more Python files as input. The Python files/modules and all additional command line parameters are handed over to Pylint.
To configure as an 'external tool' in Pycharm (after you've run Setup.py):
command: pylint-pycharm
arguments: $FilePath$
[you can also pass in a virtualenv with --venv=, and other params for pylint such as your own pylintrc file]
directory: $FileDir$
Now the messages contain a link to the line in question.
To use straight pylint, configure per these instructions:

I use sublime 3 for python coding, with plugin Anaconda for format checking. But when I read others' codes, I don't need this function, because the whole file is full of format error which I don't care about but the Anaconda lint bothers me. So I would like close the function for this "project" (not current file), what should I do?
You can control the state Anaconda linter using the anaconda_linting setting.
"anaconda_linting": false
Working with projects gives you more refined control where you want to use the linter and where not. For instance, you could disable the linter in your global settings and enable it for specific projects.
