Jest-dom 无法在 node_modules 的文件夹中找到模块

Question

当我添加到我的 test-setup.js import "@testing-library/jest-dom"; 运行任何测试时，Jest 会抛出这个错误。如果我删除导入一切正常。尝试直接在测试文件中添加导入，没有成功。

这是 test-setup.js 的样子：

import '@testing-library/jest-dom';
import { server } from 'mocks/server';

beforeAll(() => server.listen());

afterEach(() => server.resetHandlers());

afterAll(() => server.close());

错误：

Cannot find module 'css' from 'node_modules/@testing-library/jest-dom/dist/utils.js'

Require stack:
 node_modules/@testing-library/jest-dom/dist/utils.js
 node_modules/@testing-library/jest-dom/dist/to-be-in-the-dom.js
 node_modules/@testing-library/jest-dom/dist/matchers.js

尝试单独安装

npm install -D jest-dom
# or yarn
yarn add --dev jest-dom
