一、在React Router 6.x开始，路由对象的声明需要引用RouteObject。

import { RouteObject } from 'react-router-dom';const routes: RouteObject[] = [{path: '/',element: <Home />},{path: '/about',element: <About />},// ...
];

二、一些老项目使用的是React Router 5.x，一般路由对象的声明是引用RouteProps类型。

import { RouteProps } from 'react-router-dom';const routes: RouteProps[] = [{path: '/',component: Home},{path: '/about',component: About},// ...
];
