【问题描述】：
我正在尝试使用官方指南将我的 NextJS 项目从 Material UI v4 升级到 v5：https://mui.com/guides/migration-v4/
完成所有步骤后，当我启动服务器时，我的控制台中出现以下错误：
Module not found: Can't resolve 'react'
Import trace for requested module:
./../node_modules/@emotion/react/dist/emotion-react.browser.esm.js
./../node_modules/@mui/styled-engine/index.js
./../node_modules/@mui/system/esm/index.js
./../node_modules/@mui/core/Popper/Popper.js
./../node_modules/@mui/core/Popper/index.js
./../node_modules/@mui/core/index.js
./../node_modules/@mui/material/utils/index.js
./../node_modules/@mui/icons-material/utils/createSvgIcon.js
./../node_modules/@mui/icons-material/Menu.js
./components/global/LodAppBar.jsx
./pages/_app.jsx
我尝试删除我的node_modules 文件夹并重新安装所有模块，但没有成功。我已确保所有 @material-ui 软件包也已从我的 package.json 文件中删除。这些是我对 package.json 的依赖：
"dependencies": {
"@auth0/auth0-react": "^1.4.0",

尝试删除
yarn.lock和package-lock.json并重新安装。 -
