如何通过react和babel从react select cdn导入?

react-select babeljs reactjs javascript

我已经按照 React Website 但是我在使用 React-Select Library (尤其是选择组件)。

我只能使用cdn文件加载依赖项,包括位于 cdnjs

https://cdnjs.cloudflare.com/ajax/libs/react-select/2.1.2/react-select.js

我的React应用程序出现以下错误:

ReferenceError: Select is not defined[Learn More]

      <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>
  </html>

我还尝试了以下方法,它会引发相同的错误

      <script type="text/babel">

      require(['react-select'])
      import Select from 'react-select';
      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>
  </html>

我如何才能得到反应选择工作?也许
