Jest-dom在node_modules中的文件夹中找不到模块

Question

当我添加到我的测试-setup.js中时，当我运行任何测试时，import "@testing-library/jest-dom"; Jest都会抛出这个错误。如果删除导入，则一切正常。尝试直接在测试文件中添加导入，但未成功。

test-setup.js如下所示：

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'

尝试单独安装它

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