我正在观看 plural sight 的视频教程。类(class)名称是“使用 React、Flux、Webpack 和 Firebase 构建实时应用程序”。
请参阅下面的代码和所附问题的屏幕截图。每当我尝试重新构建文件时，Webpack 都会失败。有人可以告知该问题可能是什么。我目前正在使用所有最新的库。
/*webpack.config.js*/
module.exports = {
entry: {
main: [
'./src/main.js'
]
},
output: {
filename: './public/[name].js'
},
module: {
loaders: [
{
test: /\.jsx?$/,
exclude: /node_modules/,
loader: 'babel'
}
]
}
}
/*App.jsx*/
import React from 'react';
class App extends React.Component {
constructor() {
super();
this.state = {
messages: [
'hi there how are you ?',
'i am fine, how are you ?'
]
}
}
render() {
var messageNodes = this.state.messages.map((message)=> {
return (
<div>{message}</div>
);
});
return (
<div>{messageNodes}</div>
);
}
}
export default App;
/*main.js*/
import React from 'react';
import ReactDOM from 'react-dom';
import App from './components/App.jsx';
ReactDOM.render(<App/>, getElementById('container'));
/*index.html*/
<!DOCTYPE html>
<html>
<head>
<title></title>
<meta charset="utf-8" />
</head>
<body>
<div id="container"></div>
<script src="public/main.js"></script>
</body>
</html>
/*package.json */

},

}
最佳答案
解决了。答案是安装预设 npm i --save babel-preset-env babel-preset-react。然后在 webpack.config.js 中添加另一个键，在加载器中:query: {presets: ['env', 'react'] }。应该可以开始了。
