试图导入错误:useHistory没有从react-router-dom中导出

给出这个错误的useHistory:

编译失败。/src/pages/UserForm/_UserForm.js导入失败错误:useHistory没有从react-router-dom中导出。这在构建时发生错误，无法消除。

react-router-dom版本:

4.3.1

代码:

import React, { useState, Fragment } from 'react';
import FormUserDetails from './FormUserDetails';
import FormPersonalDetails from './FormPersonalDetails';
import Confirm from './Confirm';
import Success from './Success';
import Button from '@material-ui/core/Button';
import { Grid, makeStyles } from '@material-ui/core';
import { useHistory } from 'react-router-dom';


function UserForm() {
    const [step, setStep] = useState(1);
    const history = useHistory();


    const StepButtons = (props) => (
        <React.Fragment>
            <Grid item xs={4}>
                {props.value !== 'initial' ?
                    <Button variant="outlined" className={classes.button} onClick={(e) => previousStep(e)}>Back</Button> :
                    <Button variant="outlined" className={classes.button} onClick={(e) => reGenerate(e)}>Re-generate</Button>
                }
            </Grid>
            <Grid item xs={4} />
            <Grid item xs={4}>
                {
                    props.value === 'confirm' ?
                        <Button variant="outlined" className={classes.button} style={{ float: "right" }} onClick={(e) => confirm(e)}>Confirm</Button> :
                        props.value !== 'final' ?
                            <Button variant="outlined" className={classes.button} style={{ float: "right" }} onClick={(e) => nextStep(e)}>Continue</Button> :
                            null
                }
            </Grid>
        </React.Fragment>

    );
    const nextStep = (e) => {
        e.preventDefault();
        setStep(prevState => prevState + 1)
    }
    const previousStep = (e) => {
        e.preventDefault();
        setStep(prevState => prevState - 1)
    }
    const reGenerate = (e) => {
        e.preventDefault();
    }
    const confirm = (e) => {
        history.push('/')
    }
    return (
         <div>
            <h1>Hello</h1>
         </div>
    )
}
export default UserForm

当前回答

用usenavate替换useHistory 然后

const navigate = useNavigate();

然后将history。push('/path')替换为navigate('/path')

将history.replace('/path')改为navigate('/path'， {replace: true})

想要在push/navigate do navigate('/path'， {state: {name:'Xyz'}})中使用state

其他回答

在react-router-dom v6中，useHistory()被useNavigate()取代。

你可以使用:

import { useNavigate } from 'react-router-dom';
const navigate = useNavigate();
navigate('/home');

react-router-dom v5使用历史，但在v6中你应该使用usenavate钩子

用法:

import { useNavigate } from "react-router-dom";

function SignupForm() {
  let navigate = useNavigate();

  async function handleSubmit(event) {
    event.preventDefault();
    await submitForm(event.target);
    navigate("../success", { replace: true });
  }

  return <form onSubmit={handleSubmit}>{/* ... */}</form>;

V6废除了useHistory钩子。现在使用useNavigate钩子。使用

import {useNavigate} from 'react-router-dom';

假设你有一个函数名为sendData

function sendData(){
    let data = {name,email,password}
    let results = await fetch('http://localhost:8000/api/register',{
        method:'POST',
        headers:{
            'Content-Type': 'application/json',
            'Accept':'application/json'
        },
        body:JSON.stringify(data)
    });
    results = await results.json();
    console.warn("results",results);
    localStorage.setItem('user',JSON.stringify(results))
    navigate('../add',{replace:true})
}

返回使用导航('../add'，{replace:true}) 使用导航('/add')

我升级了react-router-dom的版本

5.2.0

现在它正在起作用。

2020-07-12 12:55:47

如果你必须坚持使用最新的react-router-dom v6.0.0，那么用useNavigate替换useHistory。否则，将react-router-dom降级到v5.2.0，代码就可以正常工作了。
