postcss-px-to-viewport-8-plugin

问题

使用 postcss-px-to-viewport 控制台报以下代码

postcss-px-to-viewport: postcss.plugin was deprecated. Migration guide: https://evilmartians.com/chronicles/postcss-8-plugin-migration

解决

postcss-px-to-viewport 替换 postcss-px-to-viewport-8-plugin 修复因为postcss版本导致的atRule is not a constructor问题

  "postcss-loader": "^6.1.1",

安装

npm install postcss-px-to-viewport-8-plugin -D
