【问题描述】：

我正在尝试在我的 WordPress 设置中包含 Tailwind CSS，这意味着我必须使用 post CSS。但是，当我将 postcss-loader 添加到此规则时：

        test: /\.(sass|scss)$/,
        use: [MiniCssExtractPlugin.loader, 'css-loader', 'sass-loader', 'postcss-loader']
,

我收到以下错误：

我尝试了许多不同的方法，但似乎都没有奏效。不确定我是否误解了某些内容，因为我发现的大部分材料都是针对 React 设置的。

【参考方案1】：

通过将加载程序的顺序更改为以下方式来解决问题：

      
        test: /\.(sass|scss)$/,
        use: [MiniCssExtractPlugin.loader, 'css-loader', 'postcss-sass-loader', 'sass-loader']
      ,
