sass-loader 版本问题导致编译报错记录

使用vue-cli 创建 uni-app项目，需要使用sass,安装上相关依赖包后，运行报错：

Style Loader has been initialized using an options object that does not match the API schema.  
options has an unknown property 'prependData'.

使用 vue inspect 命令查看到css loader options中有prependData的配置项，去sass-loader github上查阅更新记录发现9.0.0的版本升级中去掉了prependData，升级成了additionalData选项。

引用原文：

9.0.0 (2020-07-02)

⚠ BREAKING CHANGES

• minimum supported Nodejs version is 10.13
• prefer sass (dart-sass) by default, it is strongly recommended to migrate on sass (dart-sass)
• the prependData option was removed in favor the additionalData option, see docs
• when the sourceMap is true, sassOptions.sourceMap, sassOptions.sourceMapContents, sassOptions.sourceMapEmbed, sassOptions.sourceMapRoot and sassOptions.omitSourceMapUrl will be ignored.
