你应该将 "navbar" 改为 "Navbar"。
//navbar.js
export default function Navbar() {
return (
<div>这是导航栏组件</div>
)}
//app.js
import Navbar from './component/navbar';
组件名的第一个字符必须是大写的，并且你不需要在 navbar.js 中导入 react。
英文:
you should change navbar to Navbar
//navbar.js
export default function Navbar() {
return (
<div> this is navbar component</div>
)}
//app.js
import Navbar from './component/navbar';
function App() {
return (
<>
<h1>hello</h1>
<Navbar />
</>
);}
first character of custom component name must be Uppercase.
and you dont need import react in navbar.js
