推荐答案
Ionic Cli 在使用 --prod
选项运行时似乎无法报告正确的错误.它正在抛出无法解析'./app.module.ngfactory'"而不是正确的错误消息.
Ionic Cli seems to be having issues with reporting the correct error when running with --prod
option. It is throwing "Can't resolve './app.module.ngfactory'" instead of the correct error message.
Ionic 的开发人员 Dan Bucholtz 提出了一种解决方法来检索实际的错误消息 这里.
A developer with Ionic Dan Bucholtz suggested a workaround to retrieve the actual error message here.
与此同时,要查看应用程序中的错误并修复它们,请尝试运行:
In the meantime, to see the errors in your application and fix them, try running:
./node_modules/.bin/ngc
您可以运行上述命令来找出您的应用中真正的问题是什么.
You can run the above command to figure out what the real issue in your app is.
