Question

我正在尝试为我的离子应用程序构建生产版本。如果我运行我的应用程序，一切正常：

离子运行android

但是当我尝试使用

构建我的生产应用程序时

离子运行android --prod

我收到此错误：

无法读取属性＆＃39; componentType＆＃39;未定义的 main.js：7

我的应用程序一直停留在Splash Screen

这是我的package.json

Answer 1

命令为build而不是run。尝试：

ionic build android --release --prod

run将在您连接的设备或模拟器中构建并运行

Answer 2

问题在于＆＃34; page-name.module.ts＆＃34;使用＆＃34;离子生成页面时创建的文件＆＃34;命令。手动创建页面并再次运行它（离子运行android --prod）或（ionic build android --prod）。它对我有用。他们很快就修好了。
