Issues installing mypy in VSCode

Question

I'm trying to install the mypy linter in Visual Studio Code version 1.53 on MacOS. I've never used a linter before, so I'm not sure what to expect, though I know it should be highlighting type errors and the such. I'm trying to get mypy working in the context of a Django app.

I followed these steps and restarted VS Code a few times, but the instructions don't seem to be working. I've also gone through the settings to ensure mypy linting is enabled and even tried changing the Python > Linting: Mypy Path setting to be the full path returned when doing which mypy; this also did not work.

Lastly, I installed this package from the VS Code marketplace: Mypy . I installed it through the marketplace in VS Code and followed the virtual environment instructions in the description.

django-stubs and mypy are both installed and I configured the mypy.ini file as suggested in the PyPI docs above.

I get the following error:

Error running mypy: mypy.ini:2:1: error: Error importing plugin 'mypy_django_plugin.main': No module named 'mypy_django_plugin'

How do I fix this error?

How are things going? Just checking in to see if the information provided was helpful. — Jill Cheng, Mar 05 '21 at 08:39

In VS Code, "mypy" is one of the python code analysis tools, we usually install and use it as follows:

Install it. (pip install mypy)

Check the installation: (pip show mypy)
Select "mypy": (F1, Python: Select Linter, mypy)
Run "mypy": (F1, Python: Run Linting)

Its effect:

What about "mypy" that's being used in the pre-commit? Somehow this seems to be different – stefanbschneider May 12 '23 at 12:32
How did you get step 2 and 3? Where did you go in VSC? I'm on OSX and latest version of VSC for Silicon. Thank you – Michael1775 Aug 15 '23 at 01:33

VSCode asks you to enter the path to dmypy which is the mypy daemon. After installing mypy (ex. via conda install -c conda-forge mypy), you can find this path with which dmypy and then enter this in VSCode.

There's also an option further down `Run Using Active Interpreter` which allows you to create a per-project venv for example, install mypy in it and use this version (just set the executable to `dmypy`). – David Waterworth Apr 12 '23 at 02:08

mypy is running through ~/.mypyls, a virtualenv that needs to have plugins installed in it for mypyls to find them.

To get mypy_django_plugin in there:

cd ~/.mypyls
. bin/activate
pip install django-stubs

Adding on to previous answers, to enable Mypy, one also needs to

Open the "User Settings"
Search for Mypy Enabled

Go to settings, search for "mypy.runUsingActiveInterpreter" and check the box.

Or you install mypy "pip install mypy" globally, i.e. to your main Python environment.

Then, it works properly as shown below:
