Reactjs 测试react组件时无法识别ToContaineReact功能

我正在尝试使用

https://github.com/FormidableLabs/enzyme-matchers/blob/master/packages/jest-enzyme/README.md#tocontainreact

//App.js

import React, { Component } from "react";
// ...

import Pagination from "./components/Pagination";
// ...

export default class App extends Component {
  //  ...
  render() {
    return (
      // ...
      <Pagination />
    );
  }
}

import {mount} from 'enzyme';

import App from "../App";
import Pagination from "../components/Pagination";

it('renders component', () => {
  const wrapper = mount(<App />); 
  expect(wrapper.toContainReact(<Pagination/>)); // error
});

你用的是哪种酶？似乎

toContainReact

以前在package.json

的“依赖项”中被命名为
toContain
：{“@testing library/jest dom”：“^4.2.4”，“@testing library/react”：“^9.3.2”，“@testing library/user event”：“^7.1.2”，“enzyme”：“^3.11.0”，“enzyme-adapter-react-16”：“^1.15.2”，“jest enzyme”：“^7.1.2”，…}，

“jest酶”：“^7.1.2”。。。似乎是最新的

it('renders component', () => {
   const wrapper = mount(<App />); 
}); // test is passed, so I'm assuming no installation or configuration issues

"dependencies": {
    "@testing-library/jest-dom": "^4.2.4",
    "@testing-library/react": "^9.3.2",
    "@testing-library/user-event": "^7.1.2",
    "enzyme": "^3.11.0",
    "enzyme-adapter-react-16": "^1.15.2",
    "jest-enzyme": "^7.1.2",
    ...
  },
