Kann Config-Datei nicht lesen .eslintrc.json Fehler: Unerwartetes Token}

Question

Ich erkunde EsLint für mein React JS ES6-Projekt, und ich bin sofort fest.

{ 
    "parserOptions": { 
     "ecmaVersion": 6, 
     "sourceType": "module", 
     "ecmaFeatures": { 
      "jsx": true 
     }, 
    }, 
    "rules": { 
     "semi": 2 
    } 
} 

Was mache ich jetzt: ein .eslintrc.json genau wie here ich angelegt habe?

Cannot read config file: /Users/eric/af/frontend_app/.eslintrc.json 
Error: Unexpected token } 
SyntaxError: Cannot read config file: /Users/eric/af/frontend_app/.eslintrc.json

    at executeOnFile (/usr/local/lib/node_modules/eslint/lib/cli-engine.js:603:23) 

Meine EsLint Version:

$ eslint -v 
v2.4.0 

Ich habe versucht, auf den Namen der gleichen Konfigurationsdatei zu ändern .eslintrc.js und ich habe diese bekam:

Cannot read config file: /Users/eric/af/frontend_app/.eslintrc.js 
Error: /Users/eric/af/frontend_app/.eslintrc.js:2 
    "parserOptions": {

So (ich entfernte das Komma nach "ecmaFeatures": {"jsx": true},):

{ 
    "parserOptions": { 
     "ecmaVersion": 6, 
     "sourceType": "module", 
     "ecmaFeatures": { 
      "jsx": true 
     } 
    }, 
    "rules": { 
     "semi": 2 
    } 
}
