Question

我正在尝试构建我的应用程序的prod版本并运行命令

ionic cordova build android --prod因以下错误而失败：

Running app-scripts build: --prod --platform android --target cordova
[19:55:39]  build prod started ...
[19:55:39]  clean started ...

即使我跑ionic cordova build android --prod --verbose，也会出现类似错误。

现在按照第一个错误行 - .. Expression form not supported ( position 133:13 in the original .ts file), resolving symbol App Module in ../src/app/app.module.ts它只有

export class AppModule {}

因此，我不知道错误的原因!!!

我跑的时候 ionic cordova build android或 ionic cordova build android --debug

它会在20秒内生成APK。

如何使用--prod标志运行build命令

我在本地安装的Ionic详细信息如下：

Android的Ionic --prod版本因ngc而失败
