我想使用 React Component 来获取 id 匹配，但是在转到 url 时会出错：http://localhost:8080/portfolio/1并且对于其他 url 运行良好。错误 ：
GET http://localhost:8080/portfolio/bundle.js 404 (Not Found) 1:1
Refused to execute script from 'http://localhost:8080/portfolio/bundle.js' because its MIME type ('text/html') is not executable, and strict MIME type checking is enabled.
AppRouter.js
import React from 'react';
import { BrowserRouter, Route, Switch, Link,NavLink } from 'react-router-dom';
import Home from '../Components/Home';
import Contact from '../Components/Contact';
import PortfolioItemPage from '../Components/PortfolioItemPage.js';
import NotFound from '../Components/NotFound.js';
import Header from '../Components/Header';
const AppRouter = () => (
<BrowserRouter>
<div>
<Header/>
<Switch>
<Route path="/" component={Home} exact={true} />
<Route path="/portfolio/:id" component={PortfolioItemPage} />
<Route path="/contact" component={Contact}/>
<Route component={NotFound} />
</Switch>
</div>
</BrowserRouter>
);
export default AppRouter;
PortfolioItemPage.js
import React from 'react';
const PortfolioItemPage = (props) => {
console.log(props);
return (
<div>
<h1>Hii there...</h1>
</div>
);
};
export default PortfolioItemPage;
