I'm using ESLint with its VS Code extension to format my code.

At some point it stopped auto-formatting the code on save. I uninstalled everything and reinstalled anew: VS Code, ESLint and ESLint extension for VS Code.

I think I'm close to making the formatter work, but ESLint logs this in VS Code when I try and save a file with a linting error:

2020-10-10T10:41:45.345Z eslint:source-code-fixer shouldFix parameter was false, not attempting fixes

I guess if I find that shouldFix parameter and set it to true it'll work, but where is it?

The above solution didn't work for me. I had to explicity add the following to my VSCode settings.

    "editor.codeActionsOnSave": {
        "source.fixAll.eslint": true
    }

I think maybe something in the newest VSCode update municating this with the plugin went wrong.

I managed to fix it changing the .eslintrc.js at the root of the project.

'parserOptions': {
    'ecmaVersion': 12,
}

instead of

'parserOptions': {
    'ecmaVersion': 2018,
}

I don't know why it worked till yesterday and then stopped.... but well that solved it for me.

Configuring a default formatter resolved this for me. From the extension's page:

eslint.format.enable (@since 2.0.0): uses ESlint as a formatter for files that are validated by ESLint. If enabled please ensure to disable other formatters if you want to make this the default. A good way to do so is to add the following setting "[javascript]": { "editor.defaultFormatter": "dbaeumer.vscode-eslint" } for JavaScript. For TypeScript you need to add "[typescript]": { "editor.defaultFormatter": "dbaeumer.vscode-eslint" }.

run npm run lint this will start debugging your code with eslint and your error should be solve then,
