When using autosave with black and isort in vscode, isort does not work

Question

I want to use autosave in Visual Studio Code and apply commonly used tools like flake8, mypy, isort, and black.

Flake8, mypy, and black work fine, but isort doesn't work at all. Is there a way to solve this problem?

My settings.json file looks like this:

{
  "python.terminal.activateEnvInCurrentTerminal": false,
  "python.defaultInterpreterPath": "${workspaceFolder}\\.venv\\Scripts\\python.exe",
  "python.linting.enabled": true,
  "python.linting.lintOnSave": true,
  "python.linting.pylintEnabled": false,
  "python.linting.flake8Enabled": true,
  "python.linting.flake8Path": "${workspaceFolder}\\.venv\\Scripts\\pflake8.exe",
  "python.linting.mypyEnabled": true,
  "python.formatting.provider": "black",
  "[python]": {
    "editor.codeActionsOnSave": {
      "source.organizeImports": true
    },
    "editor.formatOnSave": true
  }
}

Answer 1

You can try adding the following line to your settings.json file:

"python.sortImports.path": "${workspaceFolder}\\.venv\\Scripts\\isort.exe"

After that, save the settings.json file and restart VS Code. Hope this answer can help you

I have solved this issue. I did not know that "isort" was a default in vscode, and so I uninstalled it.

I have reinstalled "isort". And I have modified the "settings.json" as follows:

{
  "python.terminal.activateEnvInCurrentTerminal": false,
  "python.defaultInterpreterPath": "${workspaceFolder}\\.venv\\Scripts\\python.exe",
  "python.linting.enabled": true,
  "python.linting.lintOnSave": true,
  "python.linting.pylintEnabled": false,
  "python.linting.flake8Enabled": true,
  "python.linting.mypyEnabled": true,
  "python.formatting.provider": "black",
  "editor.formatOnSave": true,
  "editor.codeActionsOnSave": {
    "source.organizeImports": true,
  },
  "isort.args": [
    "--profile",
    "black"
  ]
}

There's now a new and much better, faster, and more popular alternative now:

• ruff https://github.com/astral-sh/ruff

with

• ruff VSCode extension https://marketplace.visualstudio.com/items?itemName=charliermarsh.ruff

It is an extremely efficient implementation of isort, black, and other linting tools, available as a single package.

Then, just set up ruff to format your file on auto-save.
