无法从“node_modules/@testing-library/react/dist/pure.js”找到模块“react-dom/client”

Question

运行时npm test我收到以下错误：

Cannot find module 'react-dom/client' from 'node_modules/@testing-library/react/dist/pure.js'
Required stack:
node_modules/@testing-library/react/dist/pure.js
node_modules/@testing-library/react/dist/index.js

所有必需的软件包似乎都已安装。我重新安装了react-dom，但没有帮助。下面提供了我的测试文件中使用的导入：

import React from "react";
import { render, screen } from '@testing-library/react';
import userEvent from '@testing-library/user-event';
import '@testing-library/jest-dom';

另外提供我的package.json：

Answer 1

我认为这是因为你的 @testing-library/react 使用较新的版本，只需使用 12.1.2 版本进行测试

Answer 2

根据@testing-library/react 发行说明，version 13（及以上）已放弃对和 的支持React 17。所以使用这个库React <= 17 will cause this error (or maybe others).

您可以降级到以下 13 的任何版本@testing-library/react来修复它。在撰写本文时，最新的版本可以12.1.5与React 17.

另一个选择是将 React 升级到 18 及更高版本。

Answer 3

我还收到错误“找不到模块‘react-dom/client’”，而没有提及@testing-library/react。

看起来连接react-redux Provider的语法已经改变： https: //react-redux.js.org/introduction/getting-started （在代码块中提到“// As of React 18”） 。

为了使其正常工作，我必须确保 React 和 React-dom 使用的是 18 或更高版本，并更新了所有其他客户端 npm 包。许多需要更新：

npm update package-name --legacy-peer-deps

我花了几个小时才弄清楚这一点。希望它能帮助别人！
