我安装了一个基本的 React 应用程序
npx create-react-app appnamehere
然后我安装了 bootstrap（也尝试了 v4 和 v5）
npm install bootstrap
然后将它们加载到我的
App.jsimport "bootstrap/dist/css/bootstrap.min.css";
import "bootstrap/dist/js/bootstrap.min";

你猜怎么着，同样的事情。
CSSJS如果你想将它与React一起使用，我建议使用react-bootstrap。 https://react-bootstrap.netlify.app/
npm install react-bootstrap bootstrap
您可以查看他们的文档以了解如何使用它。就像导入组件一样。
