Angular 如何为ionic生产构建应用程序运行minify、closure、ngc、uglify等

如何确保ionic应用程序上的所有优化都在生产构建中触发

我运行的命令： 爱奥尼亚·科尔多瓦打造android——发布——产品

package.json

"scripts": {
    "start": "ionic-app-scripts serve",
    "clean": "ionic-app-scripts clean",
    "ionic:build": "node --max-old-space-size=8192 ./node_modules/@ionic/app-scripts/bin/ionic-app-scripts.js build --prod --release",
    "lint": "ionic-app-scripts lint",
  },

但在构建日志中，我看到minifycss minifyjs optimizejs都是假的。我如何让他们跑
