Chr*_*ris 5 javascript reactjs babeljs react-select
我已经按照React 网站上的步骤创建了一个React应用程序，但是我在使用React-Select 库（特别是 Select 组件）时遇到了问题。
我只能使用 cdn 文件加载依赖项，包括位于cdnjs上的 React-Select cdn 文件
https://cdnjs.cloudflare.com/ajax/libs/react-select/2.1.2/react-select.js
我的 react-app 出现以下错误：
ReferenceError: Select is not defined[Learn More]
请参阅下面的脚本和此处的代码笔

<div id="root"></div>
<script type="text/babel">
const options = [
{ value: 'chocolate', label: 'Chocolate' },
{ value: 'strawberry', label: 'Strawberry' },
{ value: 'vanilla', label: 'Vanilla' }
];
class App extends React.Component {
state = {
selectedOption: null,
}
handleChange = (selectedOption) => {
this.setState({ selectedOption });
console.log(`Option selected:`, selectedOption);
}
render() {
const { selectedOption } = this.state;
return (
<div>
Test Text
<Select
value={selectedOption}
onChange={this.handleChange}
options={options}
/>
</div>
);
}
}
ReactDOM.render(<App/>, document.querySelector("#root"))
</script>
</body>

我也试过以下抛出同样的错误

<head>

<script src="https://unpkg.com/react@15.0.0/dist/react-with-addons.min.js"></script>

我怎样才能让 React-Select 工作？也许
它会查找react-select您需要添加的最新依赖项 -
<script src="https://unpkg.com/react@16.7.0/umd/react.production.min.js"></script>
<script src="https://cdn.jsdelivr.net/npm/emotion@9.2.12/dist/emotion.umd.min.js"></script>
<script src="https://unpkg.com/react-dom@16.7.0/umd/react-dom.production.min.js"></script>
<script src="https://unpkg.com/prop-types@15.5.10/prop-types.min.js"></script>
<script src="https://unpkg.com/react-input-autosize@2.2.1/dist/react-input-autosize.min.js"></script>
<script src="https://unpkg.com/react-select@2.1.2/dist/react-select.min.js"></script>
