Question

为我的Ionic3项目运行ionic cordova build android --prod时遇到以下错误。仅ionic cordova build android上没有错误。

ionic-app-script task: "build"

[ERROR] An error occurred while running subprocess ionic-app-scripts.

我已经尝试了here上的所有解决方案，但无法正常工作。

以下是我的离子细节。

   Ionic Framework    : ionic-angular 3.9.9
   @ionic/app-scripts : 3.2.4

Cordova:

   Cordova Plugins   : cordova-plugin-ionic-keyboard 2.0.5, cordova-plugin-ionic-webview 1.1.1, (and 18 other plugins)

Utility:

最后找到了问题。根据我的角度版本，我将"@angular/compiler-cli": "^8.2.12"更改为"@angular/compiler-cli": "5.2.11"，并且效果很好。

Answer 2

删除您的node_modules文件夹。删除平台android文件夹（整个平台文件夹或只是android文件夹）。

 Run npm install

添加平台android

ionic cordova platform add android

再次构建您的应用

ionic cordova build android --prod

TypeError：对象原型只能是Object或为null：在Ionic3中未定义
