Sass Loader错误：与API模式不匹配的无效选项对象

我正在将VueJS与框架VuetifyJS（v2.0.19）一起使用。我在运行npm run serve后收到此错误：

Sass Loader已使用与API模式不匹配的选项对象进行了初始化。

我尝试了什么：我已经删除了node_modules文件夹，并将所有npm软件包和node.js重新安装/更新为最新的稳定版本。

完整的错误消息：

 error  in ./node_modules/vuetify/src/components/VRangeSlider/VRangeSlider.sass

Module build failed (from ./node_modules/sass-loader/dist/cjs.js):
ValidationError: Invalid options object. Sass Loader has been initialised using an options object that does not match the API schema.

如何解决这个问题？

似乎像这里一样的问题：https : //github.com/JeffreyWay/laravel-mix/issues/2206

解决方法是

npm uninstall --save-dev sass-loader
npm install --save-dev sass-loader@7.1.0

如果您正在使用，vue-cli 4并且为了避免发生此错误，则需要像下面的示例一样更改sass-loaderin 的配置vue.config.js，此后该错误将得到解决。

const path = require('path');

module.exports = {
  chainWebpack(config) {
    config
      .entry('app')
      .clear()
      .add('./src/core/main.js')
      .end();
    config.resolve.alias
      .set('~', path.join(__dirname, './src'))
      .set('@', path.join(__dirname, './src/core'))
      .set('#', path.join(__dirname, './src/modules'))
  },
  css: {
    loaderOptions: {
      sass: {
        sassOptions: {
          includePaths: [
            path.resolve(__dirname, 'src/core/')
          ],
          indentedSyntax: true,
        },
        prependData: '@import "~@/assets/sass/main.scss"',
      },
    },
  },
  assetsDir: '@/assets/',
}

不要忘记指定您自己的配置。请在sass-loader repo上签出配置。

如果使用vue cli 3，则与sass-loader v7not一起v8使用vue cli 3，sass-loader v7并且以前的配置仍然有效。

祝你好运和问候。

indentedSyntax是的一部分sassOptions：

sassOptions: {  indentedSyntax: true  }

例如：

{
    loader: 'sass-loader',
    options: {
        sassOptions: {
            indentedSyntax: true
        }
    }
}

因此-更改您的Webpack配置以反映这一点。

在我的情况下，我不得不降低sass-loader的性能，然后我在运行时在终端上出现了真正的错误ng serve，vue-cli-service在您的情况下，我认为这可能是v8的sass-loader的问题，这将进一步探讨

同时，这可能会有所帮助：在package.json中，编辑sass-loader以读取 "sass-loader": "7.0.1",
