如何在MaterialUI 4中使用react-jss？

npm install @material-ui/core react-jss

import React from 'react';
import { makeStyles } from '@material-ui/core/styles';
import Button from '@material-ui/core/Button';
import { createUseStyles } from 'react-jss';

const useStyles = makeStyles((theme) => ({
  button: {
    backgroundColor: 'blue',
    color: 'white',
    padding: theme.spacing(2),
  },
}));

const useStylesJSS = createUseStyles({
  button: {
    backgroundColor: 'blue',
    color: 'white',
    padding: '16px',
  },
});

const MyComponent = () => {
  const classes = useStyles();
  const classesJSS = useStylesJSS();

  return (
    <div>
      <Button className={classes.button}>MaterialUI Button</Button>
      <button className={classesJSS.button}>Custom Button</button>
    </div>
  );
};
