Reactjs 在React测试库上运行初始测试时，fsevents不是函数

我是React测试库的新手，遇到以下错误：

TypeError:fsevents不是一个函数

删除

node\u模块

文件夹和

package lock.json

文件，然后再次执行

npm安装

import React from 'react';
import { render, fireEvent, waitForElement, cleanup } from '@testing-library/react';
import App from './App';
import '@testing-library/jest-dom/extend-expect'
afterEach(cleanup)

test('make sure that I can submit a question', async () => {
  const {debug} = render(
    <App />
  ) 
debug();
})
