我有一个Angular 8，Nativescript 5代码共享应用程序，我将其更新为Angular 9和Nativescript 6。它适用于浏览器和Electron打包的桌面应用程序，但不会为移动设备构建。
构建日志的结尾显示：
CONSOLE ERROR file: node_modules/@nativescript/core/trace/trace.js:174:0: Error: Could not load CSS from app.css: ReferenceError: Can't find variable: undefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedu<…>

应用程序.scss 文件：
@import '~@nativescript/theme/scss/variables';
@import '~@nativescript/theme/scss/variables/blue';
@import "~@nativescript/theme/core";
@import "~@nativescript/theme/blue";
webpack.config 摘录.js
{
test: /[/|\]app.scss$/,
use: [
"nativescript-dev-webpack/style-hot-loader",
{
loader: "nativescript-dev-webpack/css2json-loader",
options: { useForImports: true }
},
"sass-loader"
]
},
// Angular components reference css files and their imports using raw-loader
{ test: /.css$/, exclude: /[/|\]app.css$/, use: "raw-loader" },
{ test: /.scss$/, exclude: /[/|\]app.scss$/, use: ["raw-loader", "resolve-url-loader", "sass-loader"] },
我尝试删除/hooks、/platform、package-lock.json、webpack.config.js 和/node_modules 并重建 - 仍然得到同样的错误。
我还尝试了几个版本的 app.scss 文件，有和没有/variable/导入，或者以不同的顺序。
我已经删除并重新添加了平台ios和平台Android。
我已经搜索了几个小时，类似声音问题的解决方案并没有改变任何东西。
