Using the PyCharm IDE, when setting up an external tool, how can you set up the external tools with a path relative to use the current virtual env defaults.?
An example being pylint - where I'd want the virtual env version and not the system one to run.
Not sure about older versions, but in PyCharm 5 one can use $PyInterpreterDirectory$ macro. It's exactly that we want
There's JDKPath macro you can use which points to the executable of the interpreter set for a project. You can combine this with the fact that many tools can be run by directly running their module(s) using the -m option of interpreter. Also there's issue PY-2734 New useful macros in external tools everyone can vote on.
just found your post while looking for documentation about the "variables" that could bew used when setting parameters for external tools.
No documentation but you can see a list of all the available stuff after pressing thE "INSERT MACRO" button in the Edit Tool dialog.
I don't see any reference to the interpreter path there but I usually use the virtualenv as my project path. If you are doing that too you could infer the python interpreter path from there.
In Tool Settings, set Program: to $PyInterpreterDirectory$/pylint

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 want to switch over to VS Code. I did the following to enable python with the packages I typically use, including a local utilities package on this machine:
Searched for the setting python.pythonPath and made it PycharmProjects/Project/venv/Scripts/python.exe for both this workspace and for my user
Changed my Windows user PYTHONPATH to PycharmProjects/Project/venv/Scripts/python.exe
Tried PycharmProjects/python.exe;local-utilities-directory
However, the folder I'm trying to manually set won't show up as a possible option when I click on my interpreter in the bottom right. Instead I'm defaulting to an older interpreter that doesn't have all the packages I've amassed.
While I can access some packages, while trying to pull in my personal utilities library, pip fails (the term pip is not recognized...)
I see that there are a few other ways to change the python path, however, to my understanding, whether you do it in a .json or via the IDE UI, shouldn't actually matter.
Any help would be appreciated.
So, I think I messed things up by offering too many paths.
I had to double check that the exact same path showed up first in:
Work setting pythonPath
User setting pythonPath
Windows profile path
Windows profile PYTHONPATH
I deleted the other "backup" paths, and it ended up working.
I am using Python 3.7 on windows. I installed Pycharm and successfully wrote a script which I am now trying to schedule using Windows Task Scheduler, which comes with its on set of complications. One thing I have noticed about Pycharm is I think it has created a separate file directory to store any packages I add to a script (maybe in something called "venv"? Instead of using the User/Python37/Scripts file.
This means when I try to run my script in the command prompt, python.exe looks for packages and cannot find them. Also if I go into my Pycharm project folder is see another instance of a Python Application file different than the Python Application stored in User/Python37. I think this also creates problems but I am not 100% sure.
I am hoping someone has seen this issue and can help me align where Pycharm stores packages. Any help would be greatly appreciated.
You can also simply add your script/package into your python path.
For that follow this awser : How to add to the PYTHONPATH in Windows, so it finds my modules/packages?
PyCharm creates a virtual environment (venv) where you can keep the python version and the libraries used in a specific project.
You can add libraries to the specific environment through the Pycharm GUI:
File > Settings > Project: Patterns > Project Interpreter > Install (green +)
Find your package and click Install Package in your venv.
You can see all the installed packages and their version in the path:
File > Settings > Project: Patterns > Project Interpreter
You can also use pip install, if you want to go through CLI, but be sure to use the virtual environment's pip (located in project_folder/venv/Scripts).
If for some reason you want to use the python version outside the virtual environment, go to the following path in PyCharm:
File > Settings > Project: Patterns > Project Interpreter
In the Project interpeter dropdown menu, you should find other python's location; choose the one you prefear. If you don't see your standard python version (usually in C:\python\python.exe, or something similar), you can add it by clicking on the settings menu, and specify the path to the desired python version in Base interpreter:.
In this window, you can find other settings to configure the interpreter as you want.
I have two installations of Python on a corporate Windows computer. One from the Anaconda distribution:
C:\Users\Me\AppData\Local\Continuum\anaconda3\python3.exe
Another one from a corporate installer:
C:\Users\Me\AppData\Local\Downloaded Apps\WinPython\python-3.4.3\python.exe
If I type "python" in the default "cmd" terminal or in the Git Bash, it says "command not found". Probably for the same reason, Jupyter does not allow me to create a Python 3 notebook. How do I set the paths so that Python is available system-wide? I prefer the Anaconda distribution's Python.
EDIT: Creating a new user variable PYTHONPATH and setting it to C:\Users\Me\AppData\Local\Continuum\anaconda3\ via Windows System Properties does not have an effect.
This answer describes step-by-step an approach that worked for me. However, as eryksun notes in the comment, the additional variable should not be named PYTHONPATH. I renamed it PYTHON, which works.
Strangely, adding the paths directly to the PATH variable did NOT work.
You have to add the path of your installation to the Environment variables.
Simply go to the System Properties / Environment Variables /
From there, create a new system variables and add your python path.
In the system variable section select the Path variable.
Add new variable C:\Users\Me\AppData\Local\Continuum\anaconda3\ as environment variable in your advanced System Settings.
This is from where your system will invoke the python interpreter.

I need to perform some custom settings for the python interpreter: specifically related to pyspark: the "interpeter" will actually be the spark-submit (aka pyspark) shell script. The intent is to be able to run pyspark jobs within the python console. Running within a Run Configuration would also be just fine: this would be an alternate approach.
I use IJ Ultimate - which has good python support: except well maybe for this particular use case.
Let us compare to pycharm - and specifically an ability to customize the interpreter - including setting local, remote, or virtualenv:
The Intellij Ultimate seems to lack those options: instead it is pointed to the libraries for a python sdk. That will not be sufficent for the given use case:
Here is the dropdown: notice there is no way to add a custom python interpreter.
So is there a way in Intellij to set the interpreter path? I want to set it to $SPARK_HOME/bin/pyspark ?
PyCharm and IntelliJ have the exact same options to add and configure Python code.
PyCharm just makes it easier.
Those windows do not have anything for interpreters
Pretty sure it does... You add interpreters here.
bin/pyspark is not an interpreter, it is a shell script. You just set the regular Python interpreter.You also need to add the Pyspark libraries. (See below)
Then, you configure the environment variables here (Run Configurations) (see those below)
As far as PySpark libraries go, you have to add these (use the full path, not variables)
$SPARK_HOME/python/
$SPARK_HOME/python/lib/py4j-X.X-src.zip
You also need to set these variables in the Edit Configurations window shown
SPARK_HOME = path to spark
PYTHONPATH = path to py4j-X.X-src.zip (also need to append the path to the current python interpreter's directory, I believe)
