eslint Parsing error: Unexpected token function with async

I was getting this error also, I added the following to my eslintrc:

{
  "env": {
    "node": true,
    "es6": true
  },

  "parserOptions": {
    "ecmaVersion": 8
  }
}

In my case it got fixed when I just changed from:

"parserOptions": { "ecmaVersion": 8 }

to

"parserOptions": { "ecmaVersion": 2018 }
