Please use this module  RouterModule forRoot            path      component  LoginComponent          now just replace your  lt login gt  lt  login gt  with  lt router-outlet gt  lt  router-outlet gt  thats it

If you created a separate module  eg  AppRoutingModule  to contain your routing commands you can get this same error   Error  StaticInjectorError AppModule  RouterLinkWithHref - gt  Router    StaticInjectorError Platform  core  RouterLinkWithHref - gt  Router    NullInjectorError  No provider for Router    You may have forgotten to import it to the main AppModule as shown here    NgModule     imports         BrowserModule  FormsModule  RouterModule  AppRoutingModule      declarations    AppComponent  Page1Component  Page2Component      bootstrap       AppComponent      export class AppModule

I have also received this error when developing automatic tests for components  In this context the following import should be done   import   RouterTestingModule   from   angular router testing    const testBedConfiguration       imports   SharedModule      BrowserAnimationsModule      RouterTestingModule withRoutes

Nothing works from this tread   quot forRoot quot  doesn t help   Sorry  Sorted this out  I ve managed to make it work by setting correct  quot routes quot  for this  quot forRoot quot  router setup routine      import  RouterModule  Routes  from   angular router           import  AppComponent  from    app component            const appRoutes  Routes            path   UI part1 Details   component  DetailsComponent                   NgModule         declarations            AppComponent          DetailsComponent                imports            BrowserModule          HttpClientModule          RouterModule forRoot appRoutes                 providers   DetailsService         bootstrap   AppComponent          Also may be helpful  spent some time to realize this  Optional route part      const appRoutes  Routes             path   UI part1 Details   component  DetailsComponent           path    project UI part1 Details   component  DetailsComponent          Second rule allows to open URLs like hostname test UI part1 Details id 666 and hostname UI part1 Details id 666 Been working as a frontend developer since 2012 but never stuck in a such over-complicated thing as angular2  I have 3 years experience with enterprise level ExtJS

Babar Bilal s answer likely worked perfectly for earlier Angular 2 alpha beta releases   However  anyone solving this problem with Angular release v4  may want to try the following change to his answer instead  wrapping the single route in the required array    RouterModule forRoot    path      component  LoginComponent

I had the error of      No provider for Router   It happens when you try to navigate in any service ts   this router navigate    home     like codes in services cause that error    You should handle navigating in your components  for example  at login component   login   subscribe           res    gt  this router navigate    home              error  any    gt  this handleError error      Annoying errors happens when we are newbie

Please do the import like below   import   Router   from   angular Router    The mistake that was being done was -  import   Router   from   angular router

[angular] No provider for Router?
