如何在.vue文件中将选项传递给SASS加载器以获取样式？

Posted 2021-05-04

我正在尝试配置vue-loader以使其在@import语句中包含node_modules。 scss文件的加载器配置工作正常，如下所示：

{
  test: /.(sass|scss)$/,
  use: [
    'style-loader',
    'css-loader',
    {
      loader: 'sass-loader',
      options: {
        includePaths: [path.resolve(__dirname, 'node_modules')],
      },
    },
  ],
},

所以现在我正试图在.vue文件中使用它。我想到了这样的事情：

{
  test: /.vue$/,
  loader: 'vue-loader',
  options: {
    loaders: {
      // ?{"includePaths":["C:/Users/samuel/Code/school/tinf/sem03/proj01/node_modules"]}
      sass: 'vue-style-loader!css-loader!sass-loader?' +
        `includePaths[]=${path.resolve(__dirname, 'node_modules').replace(/\/g, '/')}`,
    },
  },
},

我收到一条错误消息：

错误在./~/css-loader!./~/vue-loader/lib/style-rewriter.js?id=data-v-1ec85c08!./~/sass-loader?includePaths[]=C:/Users /samuel/Code/school/tinf/sem03/proj01/node_modules!./~/vue-loader/lib/selector.js?type=styles&index=0!./src/components/PageHeader.vue

我试过从堆栈中删除vue-style-loader和css-loader，但我仍然收到错误。

但是当我直接将选项传递给样式标记时，它可以正常工作：

<style lang="sass?{"includePaths":["C:/Users/samuel/Code/school/tinf/sem03/proj01/node_modules"]}">

如何修改加载器以使其工作？

答案

您可以将它作为includePaths传递给sass option，如下所示：

module.exports = {
  ...
  module: {
    loaders: [
      {
        test: /.scss$/,
        loaders: ["sass-loader"]
      }
    ]
  },
  sassLoader: {
    includePaths: [path.resolve(__dirname, "./node_modules")]
  }
};

另一答案

糟糕！

给定的代码工作正常。

我收到错误File to import not found or unreadable: @material/typography因为该文件不存在。我应该进口@material/typography/mdc-typography。

那是一个愚蠢的问题，我很抱歉。

无论如何，这是我的固定webpack配置：

const path = require('path');
const webpack = require('webpack');
const htmlWebpackPlugin = require('html-webpack-plugin');

const nodeModules = path.resolve(__dirname, 'node_modules');

module.exports = {
  devtool: 'source-map',
  entry: path.resolve(__dirname, './src/index.js'),
  module: {
    rules: [
      {
        test: /.js$/,
        loader: 'babel-loader',
        exclude: /node_modules/,
      },
      {
        test: /.vue$/,
        loader: 'vue-loader',
        options: {
          loaders: {
            // IMPORTANT for scss (lang="sass") in .vue files
            sass: 'style-loader!css-loader!sass-loader?' +
              `includePaths[]=${nodeModules}`,
          },
        },
      },
      {
        test: /.(sass|scss)$/,
        use: [
          'style-loader',
          'css-loader',
          // IMPORTANT for scss files
          { loader: 'sass-loader', options: { includePaths: [nodeModules] } },
        ],
      },
      {
        test: /.css$/,
        use: ['style-loader', 'css-loader'],
      },
    ],
  },
  output: {
    filename: 'bundle.js',
    path: path.resolve(__dirname, 'dist'),
  },
  resolve: {
    extensions: ['.js', '.vue'],
    alias: {
      vue: 'vue/dist/vue.js',
    },
  },
  plugins: [
    new webpack.HotModuleReplacementPlugin(),
    new HtmlWebpackPlugin({
      filename: 'index.html',
      template: 'src/index.html',
    }),
  ],
};

{
  test: /.vue$/,
  loader: 'vue-loader',
  options: {
    loaders: {
      scss: [
        { 
          loader: 'sass-loader', options: {
              // here
          }
      ]
    }
  }
