eslint "parsing error: Unexpected token {" in JSX

I've got the same error on Next.js.

These steps solved my issue:

1) Install babel-eslint:

npm install --save-dev babel-eslint

2) Add babel-eslint as a parser to eslint config

"parser": "babel-eslint"

My eslint config looks like this (.eslintrc):

{
  "env": {
    "browser": true,
    "es6": true,
    "commonjs": true,
    "node": true
  },
  "extends": ["eslint:recommended", "plugin:react/recommended"],
  "parser": "babel-eslint",
  "parserOptions": {
    "ecmaVersion": 9,
    "ecmaFeatures": {
      "jsx": true
    },
    "sourceType": "module"
  },
  "plugins": ["react"],
  "rules": {
    "react/react-in-jsx-scope": 0,
    "no-console": 1
  }
}

Eslint on its own is not good enough. First install babel-eslint:

npm install --save-dev babel-eslint

Or with yarn:

yarn add -D babel-eslint

Then add to your .eslintrc file:

"parser": "babel-eslint"

You might want to install eslint-plugin-babel as well, but I believe this is not needed
