安装好sass之后,想要在组件中使用全局变量

sass-resources-loader 安装方法

步骤1:npm i sass-resources-loader --save-dev

步骤2:修改build/utils.js

在以下代码的 上面

// https://vue-loader.vuejs.org/en/configurations/extract-css.html
return {
     
css: generateLoaders(),
postcss: generateLoaders(),
less: generateLoaders('less'),
sass: generateLoaders('sass"',{ indentedSyntax: true }),
scss: generateLoaders('sass'),
stylus: generateLoaders('stylus'),
styl: generateLoaders('stylus')
}

添加

// =========
  // SASS 配置
  // =========
  function resolveResouce(name) {
    return path.resolve(__dirname, '../src/assets/sass/' + name);
  }

  function generateSassResourceLoader() {
    let loaders = [
      cssLoader,
      // 'postcss-loader',
      {
        loader: 'sass-loader',
        options: {
          indentedSyntax: true
        }
      },
      {
        loader: 'sass-resources-loader',
        options: {
          // it need a absolute path
          resources: resolveResouce('var.sass')
        }
      }
    ];
    if (options.extract) {
      return ExtractTextPlugin.extract({
        use: loaders,
        fallback: 'vue-style-loader'
      })
    } else {
      return ['vue-style-loader'].concat(loaders)
    }
  }  

其中resolveResouce方法中的路径需改成你自己项目的sass路径,resources: resolveResouce('var.sass')中的文件名,需改为你想要全局注入的那个sass文件名

然后引用以上方法,修改

return {
    css: generateLoaders(),
    postcss: generateLoaders(),
    less: generateLoaders('less'),
    sass: generateLoaders('sass"',{ indentedSyntax: true }),
    scss: generateLoaders('sass'),
    stylus: generateLoaders('stylus'),
    styl: generateLoaders('stylus')
  }

  为

return {
    css: generateLoaders(),
    postcss: generateLoaders(),
    less: generateLoaders('less'),
    //sass: generateLoaders('sass"',{ indentedSyntax: true }),
    //scss: generateLoaders('sass'),
    sass: generateSassResourceLoader(),
    scss: generateSassResourceLoader(),
    stylus: generateLoaders('stylus'),
    styl: generateLoaders('stylus')
  }
