在依赖项中导入Sass文件时引发Rollup CommonJS插件错误

我在这里找到的一个Sapper项目上使用汇总：

昨天我运行了

npm update

，从那时起，当我运行

npm run dev

时，我得到了以下错误：

✗ client
Invalid CSS after "...-features: list": expected expression (e.g. 1px, bold), was ".append($available-"
✗ server
Invalid CSS after "...-features: list": expected expression (e.g. 1px, bold), was ".append($available-"
internal/modules/cjs/loader.js:985
  throw err;
  ^

我的汇总配置：

我尝试了

rm-rf./node\u模块和&npm安装

，但仍然得到相同的错误。看起来commonJS正在加载依赖项并找到一个期望CSS但得到Sass的依赖项。。。我完全是新手，有什么想法吗？

< P>你应该考虑安装最新版本的@ LoopUp/PultUnjjs<代码>。您当前使用的版本在Sapper中有一个bug（我在运行您的repo时遇到了这个bug，而不是问题中的bug），它在以后的版本中得到了修复

升级后，您的项目似乎启动良好

当您进行升级时，请升级其他主要的版本升级，很可能大多数升级都不会出错
