Mar*_*gan 7 vue.js tailwind-css vuejs3
我正在使用没有 Vite 的Vue版本 3.2.10 并尝试安装Tailwind CSS版本2.2.14 (最新)。
重要提示:Vue 版本 3.0.6 开始支持 PostCSS 8(有关更新,请参阅 GitHub 文档中的“功能”下的第 3 点)
仔细遵循安装说明后,然后运行npm run serve我不断收到此错误:
error in ./src/assets/main.css
Syntax Error: Error: PostCSS plugin tailwindcss requires PostCSS 8.

这是我的 package.json 文件:

如上所述,Vue 3.0.6 及更高版本肯定支持 PostCSS 8。此外,“ PostCSS 7 兼容性构建”的 Tailwind CSS 说明不起作用。
按照这些说明操作后,我收到此错误:

感谢您的帮助!
看来问题(在某些情况下,无论如何)与 VueJS 没有直接关系,而是与 vue-cli 相关。
对我有用的解决方案是:
npm uninstall tailwindcss @tailwindcss/postcss7-compatnpm install tailwindcss@latest postcss@latest autoprefixer@latest就是这样!
注意:这不是我的作品。Lindsay Wardell (@lindsaykwardell)指导我在这个 Vuejs 论坛上发表了一篇帖子,其中包含Thomas Castelly的解决方案(也没有 StackOverflow 句柄)。
