Question

我正在尝试将材料ui添加到我的反应组件中。这是我写的代码。（我的完整代码位于https://github.com/abhitechdojo/MovieLensReact）

import React from 'react';
import mui from 'material-ui';

var ThemeManager = new mui.Styles.ThemeManager();
var Colors = new mui.Styles.Colors;

class App extends React.Component {
    constructor() {
        super();
        ThemeManager.setPalette({
            primary1Color: Colors.blue500,
            primary2Color: Colors.blue700,
            primary3Color: Colors.blue100,
            accent1Colors: Colors.pink400
        });
        this.state = {
            messages : [{id: 1, text: 'Hi'}, {id: 2, text: 'Hello'}, {id: 3, text: 'World'}, {id: 4, text: 'test'}]
        };
    }

    static childContextTypes = {
        muiTheme: React.PropTypes.object
    };

    getChildContext() {
        return {
            muiTheme: ThemeManager.getCurrentTheme()
        };
    }

    render() {
        var messageNodes = this.state.messages.map((message) => {
            return (<div key={message.id}>{message.text}</div>);
        });
        return (<div>{messageNodes}</div>);
    }
}

export default App;

我的.babelrc文件看起来像

{
    presets: ["es2015", "react"],
    "plugins": ["transform-class-properties"]
}

但是当我运行webpack时会出现错误

ERROR in ./src/controls/App.jsx
Module build failed: SyntaxError: /Users/abhishek.srivastava/MyProjects/MovieLensReact/src/controls/App.jsx: 
Missing class properties transform.

webpack: bundle is now VALID.

Answer 1

在你的webpack.conf中：

改变：

loaders: ['react-hot', 'babel?presets[]=es2015&presets[]=react']

到：

loaders: ['react-hot', ‘babel-loader’]
