如果导入了events-polyfill，则React Datepicker无法正常工作

Question

我已经完成了react-datepicker包的基本设置，它正在运行。但是，在我们的应用程序中，我们也使用events-polyfill包。当这两个包同时使用时，react-datepicker无法正常工作。

import React from "react";
import ReactDOM from "react-dom";
import DatePicker from "react-datepicker";
import "events-polyfill";

import "react-datepicker/dist/react-datepicker.css";
import "./styles.css";

function App() {
  return <Example />;
}

// CSS Modules, react-datepicker-cssmodules.css
// import 'react-datepicker/dist/react-datepicker-cssmodules.css';

class Example extends React.Component {
  constructor(props) {
    super(props);
    this.state = {
      startDate: new Date()
    };
    this.handleChange = this.handleChange.bind(this);
  }

  handleChange(date) {
    this.setState({
      startDate: date
    });
  }

  render() {
    return (
      <DatePicker
        selected={this.state.startDate}
        onChange={this.handleChange}
      />
    );
  }
}

const rootElement = document.getElementById("root");
ReactDOM.render(<App />, rootElement);

但是：Kua zxsw指出

文件中突出显示为罪魁祸首：

events-polyfill index.js

完全没问题是什么问题。

尝试更新events-polyfill包。

看起来像当前版本options.once = Boolean(options.once); 有针对这种情况的修复。

这是修复https://github.com/lifaon74/events-polyfill/blob/master/src/EventListenerInterceptor.js#L105的提交它针对2.1.1但是npm只有2.1.0
