                {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>
                }

    );
    const nextStep = (e) => {
        e.preventDefault();
        setStep(prevState => prevState + 1)
    }

    }
    const reGenerate = (e) => {

react-router-dom v6 useHistory()中被替换为useNavigate().

您可以使用:

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