Webpack 2-装载机意想不到的角色@

Question

我有下一个webpack 2规则的配置，运行webpack时抛出了下一个错误：

Unexpected character '@' (1:0)
You may need an appropriate loader to handle this file type.
| @media screen and (min-width: 40em) {
|   .feature {
|     margin-bottom: 8.75rem;
 @ ./~/style-loader?{"camelCase":true,"localIdentName":"[name]_[local]_[hash:base64:3]","modules":true}!./~/postcss-loader!./~/resolve-url-loader!./~/sass-loader?{"sourceMap":true,"outputStyle":"expanded","include":["/opt/inmoblex/current/inmoblex/cfg/src/styles","node_modules"]}!./src/components/LandingFeature/styles.scss 4:14-310

出什么事了？

:)

谢谢你的帮助

在使用style-loader、resolve-url-loader和postcss-loader处理.scss之后，您将使用sass-loader。结果仍然是CSS，所以应该有一个css-loader将其转换为JavaScript。因为您使用的是isomorphic-style-loader，所以不需要style-loader，从传递给它的选项来看，看起来应该是css-loader。所以将style-loader重命名为css-loader

{
  test: /\.scss/,
  use: [
    { loader: 'isomorphic-style-loader' },
    {
      loader: 'css-loader',
      options: {
        camelCase: true,
        localIdentName: '[name]_[local]_[hash:base64:3]',
        modules: true
      }
    },
    { loader: 'postcss-loader' },
    { loader: 'resolve-url-loader' },
    {
      loader: 'sass-loader',
      options: {
        sourceMap: true,
        outputStyle: 'expanded',
        include: [
          path.resolve(__dirname, "./src/styles"),
          "node_modules",
        ],
      }
    },
  ]
},
