现在有一个项目，有PC端和移动端，我一起写在了一个项目包里，但是PC端的不需要pxtorem，移动端的需要pxtorem，我配置了半天，不会了。
现在的module是这样的

module: {

      }
      // ** STOP ** Are you adding a new loader?
      // Make sure to add the new loader(s) before the "file" loader.
    ],
  },

我想的是使用include 和 exclude 来分别打包两个文件夹下的内容
主要是下面的这段

{
        test: /\.(css|scss)$/,
        include:path.resolve(__dirname, '../src/routes/Mobile'),
        use: [
          require.resolve('style-loader'),
          {
            loader: require.resolve('css-loader'),
            options: {
              importLoaders: 1,
              sourceMap: true,
              modules: true,
              localIdentName:'[path][name]__[local]--[hash:base64:5]',
            },
          },
          {
            loader: require.resolve('postcss-loader'),
            options: {
              // Necessary for external CSS imports to work
              // https://github.com/facebookincubator/create-react-app/issues/2677
              ident: 'postcss',
              plugins: () => [
                require('postcss-flexbugs-fixes'),
                autoprefixer({
                  browsers: [
                    '>1%',
                    'last 4 versions',
                    'Firefox ESR',
                    'not ie < 9', // React doesn't support IE8 anyway
                  ],
                  flexbox: 'no-2009',
                }),
              ],
            },
          },
          {
            loader: "sass-loader" // 将 Sass 编译成 CSS
          },
        ],
      }

本来以为是oneOf的问题，所以在rule底下单独又加了一个test，但是也没用。

现在这样的情况是

要么exclude生效，exclude路径下的所有css都不打包。
include就是不生效。

要么全部都用了pxtorem打包了。

完整的配置图这个是没有分开打包的时候初始的，是react-cli配置的一个。
