[英]react-router Link is not working
我試圖在反應中創建一個簡單的鏈接。 這是代碼:
import React from 'react';
import { Link } from 'react-router';
class List extends React.Component{
render() {
return (
<div>
<p>please choose from repository below.</p>
<ul>
<li><Link to={"/react"}>React</Link></li>
</ul>
</div>
);
}
}
export default List;
這是我的package.json:
"dependencies": {
"chance": "^1.0.9",
"history": "^4.6.1",
"react": "^15.5.4",
"react-dom": "^15.5.4",
"react-router": "^4.1.1",
"react-router-dom": "^4.1.1",
"superagent": "^3.5.2"
我使用以下命令來運行我的代碼:
的WebPack-DEV-服務器
bundle.js:1004 Warning: React.createElement: 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. Check the render method of `List`.
in List (created by Route)
in Route
in div
in Router (created by HashRouter)
in HashRouter
如果我刪除
<li><Link to={"/react"}>React</Link></li>
從我的代碼然后頁面正確加載。 我是否使用在組件上創建鏈接的舊方法?
任何提示都表示贊賞......
Link現在是react-router-dom包的一部分。 所以你應該將導入更改為:
import { Link } from 'react-router-dom';
您需要從react-router-dom
導入Link
,您可以在此處查看示例。 此外,不需要使用括號,您只需執行以下操作: <Link to="/react">React</Link>
。
