React.createElement: type is invalid

Question

我是新接触react不久，想用antd+react自己做一个demo，之前有写过这样类似的结构，但是不知道为什么这次就报这样的错，自己排了快一个小时了，也不知道什么原因，求助求助上面这个是组件部分 <div className = 'main-content' style = {{padding: '1rem'}}>    <AccountSelectInfo / ></div>这个是报错3warning.js?0260:33 Warning: React.createElement: type is invalid -- expected a string (for built-in components) or a class/function (for composite components) but got: undefined. You likely forgot to export your component from the file it's defined in. Check the render method of AccountSelectInfo.

Answer 1

错误的地方应该是FormItem组件，应该是let FormItem = Form.Item; Item是大写的；Form.item的值为undefined
