忽略element的scss字符集，报错: @charset" must be the first rule in the file

方法一：

在vite.conifg.ts中的css节点增加

// 忽略scss字符集，报错: @charset" must be the first rule in the file
      postcss: {
        plugins: [
          {
            postcssPlugin: 'internal:charset-removal',
            AtRule: {
              charset: (atRule) => {
                if (atRule.name === 'charset') {
                  atRule.remove()
                }
              }
            }
          }
        ]
      }

方法二：

在根目录下创建postcss.config.js

module.exports = {
  plugins: [
    // 移除打包element时的@charset警告
    // 忽略element的scss字符集，报错: @charset" must be the first rule in the file
    {
      postcssPlugin: 'internal:charset-removal',
      AtRule: {
        charset: (atRule) => {
          if (atRule.name === 'charset') {
            atRule.remove()
          }
        }
      }
    }
  ]
}
