ionic-angular tabs module not found-CodePudding

I updated my angular libraries and for some strange reasons my ionic angular project is now broken. the error i see on running the app in the console is

ERROR Error: Uncaught (in promise): Error: Cannot find module './tabs/tabs.module'
Error: Cannot find module './tabs/tabs.module'

I have tried nuking nodes_module and doing fresh npm i. but no luck. I created a new test project with tabs template and tried to compare and dont see anything different.

i did check specifically tabs.module.ts . what else i should i look to debug this issue?

CodePudding user response：

Looks like upgrading messed up things and i added the below entry to the app-routing.module.ts file

 { 
    path: '', 
    loadChildren: () => import('./tabs/tabs.module').then(m => m.TabsPageModule)
  },
