reactbootstrap手风琴未加载

我正在尝试在 Bootstrap 5 中使用 react-bootstrap。我想在我的一个页面中使用 Accordion。为此，我只是从这个页面复制了结构-> https://react-bootstrap.netlify.app/components/accordion/。但是当我打开页面时，浏览器显示此错误-

Error: Element 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, or you might have mixed up default and named imports.
Check the render method of `Questions`.


这是我使用这个组件的代码

import Accordion from 'react-bootstrap/Accordion';
const QuestiOns= () => (


Question #1

Answer to the Question #1



Question #2

Answer to the Question #2



);
export default Questions;


其他详情：

1. “引导程序”：“^5.0.2”


2. “反应”：“^ 17.0.2”


3. “反应引导”：“^ 1.6.1”

导入/导出组件时我错过了什么吗？TIA。
