如何修复` `TypeError:使用Jest测试i18next时无法读取未定义`的属性'type‘

import i18next from 'i18next';
import { initReactI18next } from 'react-i18next';

beforeEach(() => {
  i18next.init({
    lng: 'en', // 设置默认语言
    resources: {
      en: {
        translation: {
          "key": "value"
        }
      }
    },
    react: {
      useSuspense: false
    }
  });
});

jest.mock('i18next', () => ({
  init: jest.fn(),
  t: (key) => key // 简单地返回键作为翻译
}));

npm install i18next react-i18next --save-dev

"jest": {
  "testEnvironment": "jest-environment-jsdom-sixteen"
}

import i18next from 'i18next';
import { initReactI18next } from 'react-i18next';
import { render, screen } from '@testing-library/react';
import MyComponent from './MyComponent';

jest.mock('i18next', () => ({
  init: jest.fn(),
  t: (key) => key
}));

beforeEach(() => {
  i18next.init({
    lng: 'en',
    resources: {
      en: {
        translation: {
          "welcome": "Welcome to React"
        }
      }
    },
    react: {
      useSuspense: false
    }
  });
});

test('renders welcome message', () => {
  render(<MyComponent />);
  const linkElement = screen.getByText(/Welcome to React/i);
  expect(linkElement).toBeInTheDocument();
});
