根据https://github.com/bvaughn/react-virtualized-select
尝试使用'react-virtualized-select'我们在我们的应用程序中使用require.js 从npm获取后导入并且没有导入css ....如此处所述 https://github.com/bvaughn/react-virtualized-select#simple-example
注意:发布完整代码以便于理解上下文如果我删除了VirtualizedSelect标记,请忽略其余代码中的任何短缺内容,因为错误消失了

获得此异常

无法找到我在这方面提供任何帮助的错误将不胜感激请找到我的package.json条目

答案 0 :(得分:1)
问题出在以下几行:
var VirtualizedSelect = require('react-virtualized-select');
需要更改为:
var VirtualizedSelect = require('react-virtualized-select').default;
错误消息是因为导入的内容不是React组件,而且似乎与React Virtualized Select的来源中export default
已被转移的方式有关进入ES5。

我想你忘了为类组件添加 render 方法。
结帐以下代码
var React = require('react');
var ReactDOM = require('react-dom');
var VirtualizedSelect = require('react-virtualized-select');
module.exports = React.createClass({
componentName: 'Search',
getDefaultProps() {
return {};
},
getInitialState() {
return {
error: false,
authenticated: false,
visible: true,
data: null,
showAccountSelection: false,
selected: null,
search: '',
optionPartnerList: []
};
},
componentDidMount () {
var qS = queryString.parse(location.search);
if (qS && qS.search) {
this.setState({search: qS.search, visible: true});
}
this._unsubscribe = AppStore.listen(Utils.createRefluxComponentDispatcher(this));
},
componentDidUpdate: function () {
if (this.refs.inputSearch) {
this.refs.inputSearch.focus();
this.refs.inputSearch.select()
}
},
componentWillUnmount () {
this._unsubscribe();
}
render() {
return (
<div style={{float:'left'}} className="search-div">
{this.searchIcon()}
<div className="overlay" style={overlayStyle}>
{closeButton}
<div className="global-search center-content-wrapper" style={style}>
<form id="searchFormComponent" ref={function(){$('#searchFormComponent').show('fast')}}

{this.errorRender()}

placeholder="SEARCH FOR ACCOUNT" required
style={{marginBottom:'1px'}} disabled={componentDisabled}

</input>
<VirtualizedSelect

<button id="searchbutton" className="btn btn-lg btn-primary btn-block t-font f-1"
