我目前正在尝试让 sass 与我的 webpack 应用程序一起工作。我已经成功配置style-loader& css-loader。但是，当我尝试实施时，sass-loader我收到以下错误：

bundle.js:598 Uncaught Error: Cannot find module "!!./../../css-loader/index.js!./../../sass-loader/index.js!./index.js?http:/localhost:8000"

让我带您完成我如何安装style-loader&的步骤css-loader。

  1. 冉npm install style-loader css-loader --save-dev

  2. 在 webpack.config 中添加了加载器：

    module: {
  loaders: [
    {
      test: /\.jsx?$/,
      exclude: /node_modules/,
      loader: 'react-hot!babel'
    },
    {
      test: /\.css$/,
      exclude: /node_modules/,
      loader: "style-loader!css-loader",
    }
  ]
}

  3. 创建css文件夹并放置在那里myStyle.css

  4. 将样式表导入反应组件require(../../css/myStyle.css

这行得通，我没有任何问题。在此之后，我尝试添加sass-loader. 我采取的步骤与第一步非常相似。

  1. 冉npm install sass-loader node-sass --save-dev

  2. 将加载器添加到 webpack.config

    module: {
  loaders: [
    {
      test: /\.jsx?$/,
      exclude: /node_modules/,
      loader: 'react-hot!babel'
    },
    {
      test: /\.css$/,
      exclude: /node_modules/,
      loader: "style-loader!css-loader",
    },
    {
      text: /\.scss$/,
      exlude: /node_modules/,
      loader: "style-loader!css-loader!sass-loader"
    }
  ]
}

  3. 更改myStyle.css为myStyle.scss。

  4. 将样式表导入反应组件require('../../myStyle.scss')

在此之后，我收到上面粘贴在 DOM 中的错误。这是控制台向我发出的错误：

任何建议或帮助将不胜感激。现在我要睡觉了，明天早上再回来检查。祝大家编码愉快，祝大家晚安！

您似乎正在尝试加载 jsx 文件（在 ./~/css-loader!./~/sass-loader!./src/index.jsx中）而不是 css/scss/sass 文件。
