Question

我尝试使用Enzyme为以下React组件配置Jest：

import React from "react";
import PropTypes from "prop-types";

class App extends React.PureComponent {
    render() {
        return (
            <section className='container-menu'>
                <div className='item-logo'>
                    <img width='70' src='/images/logo.png'/>
                </div>
                <div className='item-menu'>
                    {/*<AppMenu/>*/}
                </div>
                <div className='item-page-header'>
                    {this.props.children}
                </div>
            </section>
        );
    }
}

export default App;

根据http://airbnb.io/enzyme/docs/installation/react-15.html，配置酶在Jest中运行的方法是根据以下测试代码：

import App from "./App";
import React from "react";
import {configure, shallow} from 'enzyme';
import Adapter from 'enzyme-adapter-react-15';

describe("App", () => {
    configure({adapter: new Adapter()});
    const wrapper = shallow(<App/>);
    expect(wrapper.exists()).toBe(true);
});

当我运行测试运行器时，我收到以下错误：

TypeError：超级表达式必须为null或函数，而不是未定义

我有同样的问题。然后结果表明，ases-adapter-react-15也取决于ases@3.x.x

我通过运行npm i --save-dev enzyme@latest解决了这个问题。
