make sure both eslint and eslint-config-next are installed

This happened to me because I somehow ended up with an extra .eslintrc.json file outside of my Next project directory which was getting picked up by my IDE (WebStorm)

For example:

parent-folder
    .eslintrc.json <-- Delete this
    next-folder
        pages
        package.json
        .eslintrc.json <-- This one is correct
        tsconfig.json
