使用 Craco 从 Tailwind v2 升级到 v3 React Js 的问题

我使用的是 Tailwind v2，当我将它升级到 v3 时，出现了 Postcss 8 错误 （错误：PostCSS 插件 tailwindcss 需要 PostCSS 8。）。我试图解决此错误但没有成功。有什么办法可以在 React Js 中使用 Tailwind Cli。 Error ScreenShoot

tailwindcss v3 只支持Postcss8，目前只有create-react-app v5 支持Postcss8。所以你需要将 create-react-app 升级到 v5。在 create-react-app v5 中也不需要 craco

为了安全起见，首先确保在迁移之前结帐到不同的分支或将代码推送到 github。

1.First 运行 npm uninstall @craco/craco autoprefixer postcss tailwindcss
删除 craco.config.js 文件
删除 tailwind.config.js
现在只需按照 offical tailwindcss 文档
2. 运行 npm install -D tailwindcss postcss autoprefixer
3.npx tailwindcss init -p
从 tailwindcss 文档中复制粘贴 tailwind.config.js 文件
4.npm install react-scripts@latest
5.现在npm start
6. 更改 npm 脚本：
“开始”：“反应脚本开始”
“构建”：“反应脚本构建”
“测试”：“反应脚本测试”
“弹出”：“反应脚本弹出”
稍后将您以前的 tailwind.config 主题粘贴到新的 tailwind.config.js 文件中。

步骤的顺序可能重要也可能无关紧要，但遵循这些步骤对我有用。
