reactjs - 更新到material-ui@0.15.0-beta.1后我无法使用material-ui组件

Question

我在控制台中收到此消息:

Failed Context Types: Required context muiTheme was not specified in AppBar

AppBar.js:158 Uncaught TypeError: Cannot read property 'prepareStyles' of undefined

我的组件中只有一个 AppBar 我认为它应该有效，但是...... 这是我非常简单的代码:

import React from 'react';
import {AppBar} from 'material-ui';


    export class MyComponent extends React.Component {

        render() {
            return (
                <div>
                    <AppBar
                        title="Title"
                    />

                </div>
            );
        }

    }

感谢您的帮助...

使用material-ui@0.15.0.beta-1，一些事情发生了变化。

您可以查看下面的链接以了解更多详细信息。 https://github.com/callemall/material-ui/blob/master/CHANGELOG.md

因此，通过这些更改，您的代码将变为:

    import React from 'react';
    import AppBar from 'material-ui/AppBar';
    import baseTheme from 'material-ui/styles/baseThemes/lightBaseTheme';
    import getMuiTheme from 'material-ui/styles/getMuiTheme';

        export class MyComponent extends React.Component {

            getChildContext() {
                return { muiTheme: getMuiTheme(baseTheme) };
            }

            render() {
                return (
                    <div>
                        <AppBar
                            title="Title"
                        />

                    </div>
                );
            }        
        }

        MyComponent.childContextTypes = {
            muiTheme: React.PropTypes.object.isRequired,
        };
