将 ReactJS 与 npm 一起使用并给出以下错误（意外标记）

Question

任何信息都会很有帮助，最初我运行 npm install babel-loader 命令也是如此。

我有

ERROR in ./app-client.js Module build failed: SyntaxError: /Users/dawatramani/ReactNodejs/app-client.js:

意外令牌 (4:13)

Answer 1

你好像忘了在 render 方法中粘贴一个 Component :)

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

Answer 2

那么对于 reactJS 的当前版本，您不应该使用 React.render()，而应该使用 ReactDOM.render() 和 import ReactDOM from "react-dom"。我想这会解决你的问题。

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

这是 0.14 引入的最新变化。 React 现在分为核心库和 DOM 适配器。渲染现在通过 ReactDOM.render.

完成
