Error in inject SASS in bundle

Error in inject SASS in bundle

The package has the following dependencies:

"devDependencies": {
     "nativescript-dev-webpack": "~ 1.5.1",
     "node-sass": "^ 4.13.1",
     "sass-loader": "^ 8.0.2",
     "typescript": "~ 3.5.3",
     "webpack": "^ 4.42.1"
   },

However, when I run the tns run an error occurs in the bundle.js, saying: ERROR SyntaxError: Unexpected identifier 'defined undefined undefi'.

The bundle.js file contains the following:

WebPack SCSS Configuration:
{
test: /.scss$/,
use: [
"nativescript-dev-webpack/css2json-loader",
"sass-loader"
]
},

首先使用列出的 nativescript-dev-webpack、node-sass、sass-loader、TypeScript 和 webpack 相依套件，透過 tns run 重現故障。檢查 bundle.js 和所示的 WebPack SCSS 設定，然後驗證 SCSS 注入不再產生回報的 Unexpected identifier 錯誤。
