I also had the same issue  Tried all ways and it didn t work out until I added the following in app module ts  import   Ng4LoadingSpinnerModule   from  ng4-loading-spinner     And add the following in your imports in app module ts  Ng4LoadingSpinnerModule forRoot     This case might be rare but I hope this helps someone out there

I had the same problem and later I realised that my app-routing module ts was inside a sub folder called app-routing  I moved this file directly under src and now it is working   Now app-routing file has access to all the components

I think that your mistake is in that your route should be product instead of  product    So more something like     children             path           component  AboutHomeComponent                 path   product        component  AboutItemComponent

This May be helpful     I personally prefer dynamic import  angular 8    path   pages   loadChildren       gt  import    pages pages module   then mod   gt  mod PageModule      In child routing it should look like    path   about   component  AboutComponent     Note that there is no pages in path of child routing and in routerLink or nsRouterLink it should look like routerLink   pages about   I hope thi help someone out there

I had the issue the imports for the routing module must come after the child module  this might not be directly related to this post but it would have helped me if I read this   https   angular io guide router module-import-order-matters  imports      BrowserModule    FormsModule    ChildModule    AppRoutingModule

If you are passing id through url please use below  imports        BrowserModule      FormsModule      HttpModule      RouterModule forRoot           path   Employees   component  EmployeesComponent  pathMatch   full             path   Add   component  EmployeeAddComponent  pathMatch   full               path   Edit  id   component  EmployeeEditComponent            path   Edit   component  EmployeeEditComponent              path      redirectTo   Employees   pathMatch   full                   i e If you are passing any id we need to both url edit with id and edit url alone
