无法使用离子Cordova构建android --prod --release构建apk

Question

我的应用需要花费很长时间，因此在启动屏幕后显示主页，所以我可以使用

ionic cordova  build android --prod --release

但是我遇到了错误：

[20:28:35]  ionic-app-script task: "build"
[20:28:35]  Error: ./src/app/main.ts Module not found: Error: Can't resolve './a
pp.module.ngfactory' in
            'D:\losts\src\app' resolve './app.module.ngfactory' in 'D:\losts\src
\app' using description file:
            D:\losts\package.json (relative path: ./src/app) Field 'browser' doe
sn't contain a valid alias configuration
            after using description file: D:\losts\package.json (relative path:
./src/app) using description file:
            D:\losts\package.json (relative path: ./src/app/app.module.ngfactory

\losts\src\app\app.module.ngfactory.json
            doesn't exist as directory 

问题出在哪里或者我可以做些什么来使其更快
