Answer 1

Nun mit aktuellen Versionen von reactJS sollten Sie nicht React.render() verwenden, sondern verwenden Sie ReactDOM.render() und import ReactDOM from "react-dom". Ich denke, das wird dein Problem lösen.

ReactDOM.render(<ComponentName />,document.getElementById('react-container')); 

Dies ist eine sehr neue Änderung mit 0,14 eingeführt. React wird jetzt in eine Core-Bibliothek und den DOM-Adapter aufgeteilt. Das Rendern erfolgt jetzt über ReactDOM.render.

Es scheint, wie Sie eine Komponente einfügen vergessen in Render-Methode :)

React.render(,document.getElementById('react-container'));
