"SyntaxError: Unexpected token {" when trying to run ESLint script

Question

I’m having issues when trying to run a lint script "lint:fix": "eslint --fix --ext .js,.jsx .” npm run lint:fix

I keep getting this error prompted and it only seems to have come about since updating my eslint deps in line with the airbnb rules (I used npx install-peerdeps --dev eslint-config-airbnb)

Error:

/Users/ME/Projects/MYPROJECT/node_modules/eslint/bin/eslint.js:93
        } catch {
                ^
SyntaxError: Unexpected token {
    at createScript (vm.js:80:10)
    at Object.runInThisContext (vm.js:139:10)
    at Module._compile (module.js:607:28)
    at Object.Module._extensions..js (module.js:654:10)
    at Module.load (module.js:556:32)
    at tryModuleLoad (module.js:499:12)
    at Function.Module._load (module.js:491:3)
    at Function.Module.runMain (module.js:684:10)
    at startup (bootstrap_node.js:187:16)
    at bootstrap_node.js:608:3

However, running the following works as expected: npx eslint specific/file.js —fix



This is my .eslintrc file:



{
    "env": {
        "browser": true,
        "es2020": true
    },
    "extends": ["plugin:react/recommended", "airbnb", "prettier", "prettier/react"],
    "parser": "babel-eslint",
    "parserOptions": {
        "ecmaFeatures": {
            "jsx": true
        },
        "ecmaVersion": 2018,
        "sourceType": "module"
    },
    "plugins": ["react"],
    "rules": {}
}

And these are my current eslint deps:



    "eslint": "7.10.0",
    "eslint-config-airbnb": "18.2.0",
    "eslint-config-prettier": "^2.9.0",
    "eslint-plugin-import": "2.22.1",
    "eslint-plugin-jsx-a11y": "6.3.1",
    "eslint-plugin-react": "7.21.3",
    "eslint-plugin-react-hooks": "4.1.2",
    "eslint-watch": "3.1.2",

Any help would be great!

 Thanks a lot!

Optional catch binding was introduced in ES2019.

The specified ESLint version should be used with Node version that supports it (10 or later).
