Attempted import error: 'useLocation' is not exported from 'react-router-dom'

Question

React version:
"react": "^16.13.0",
"react-dom": "^16.13.0",
"react-router-dom": "5.0.1",
"react-scripts": "3.4.0",

js代码为

import {useLocation} from "react-router-dom";
const location = useLocation();

……问题出在哪里？

Answer 1

那个钩子是 added in 5.1.0。

Answer 2

尝试卸载并重新安装“react-router-dom” 然后，为了安全，运行 npm i 和 npm start。此外，如果您使用的是 TS，则还必须安装“@types/react-router-dom”作为开发依赖项
