Cannot match any routes

My component shows up but i get an error message when the page is loaded. I can't seem to solve the error message at all after looking at a bunch of resources.

Error

EXCEPTION: Error: Uncaught (in promise): Cannot match any routes. Current segment: 'index.html'. Available routes: ['/login'].

main.component.ts is in index.html and as soon as the page loads it shows the above error message.

import { Component } from '@angular/core';
import { Routes, ROUTER_DIRECTIVES, ROUTER_PROVIDERS } from '@angular/router';

import { LoginComponent } from './login/login.component';

@Component({
    selector: 'main-component',
    template: 
      ' <header>
           <h1>Budget Calculator</h1>
           <a id='login' [routerLink]="['/login']">Login</a>
           <router-outlet></router-outlet>
        </header> '
    directives: [ROUTER_DIRECTIVES],
    providers: [ROUTER_PROVIDERS]
})

@Routes([
    {path: '/login', component: LoginComponent}
])

export class MainComponent {}

login.component.ts is routed through the main.component.ts and does show when I click on the link despite the error message. Right now I have it styled to popup over the other elements in main.component but would like it to be the only component that shows on the page. Basically replace main.component in index.html with login.component if this possible instead of doing a whole bunch of styling to display: none.

import { Component } from '@angular/core';

@Component({
    selector: 'login',
    template: 
        ' <div id="login-pop-up">
              <h6 class="header_title">Login</h6>
              <div class="login-body">
                   Some fancy login stuff goes here
              </div>
          </div> '
})

export class LoginComponent {}

if you have child component and you want to navigate use this way

router servive

const routes: Routes = [
  {
    path: '',
    component: LoginComponent
  },
  {
    path: 'home',
    component: HomeComponent,
    children: [
      {
        path: 'enter',
        component: EnterDetailsComponent,
      },
      {
        path: 'find',
        component: FindDetailsComponent,
      }
    ]
  }
];

@NgModule({
  imports: [RouterModule.forRoot(routes)],
  exports: [RouterModule]
})
export class AppRoutingModule { }

use navigate([]) method this way

component constructor

this is how this._router comes

constructor( private _router: Router) {}

this._router.navigate(['/home/find']);

When I have had this problem I typically add 

<base href="./">

to the <head> <base href="./"> </head> of html file.

Then when importing any files in NG2 

import { Auth }                 from './auth.service';

This is the prefered way to do base per the documentation, enter image description here

just add a route for '' the exception will go.

{ 
    path: '', 
    component: HomeComponent 
}

Also ensure you have a <base href="/"> tag at the beginning of the <head> tag or provided by boostrap(...) as explained in Angular 2 router no base href set

Hint: The @angular/router router also is deprecated as @angular/router-deprecated and a new router will be shipped again :-/ If you are about to switch to @angular/router it's probably better to postpone until the new and hopefully final router is available.

plz make sure <base href="/"> tag in your head tag and you can use useAsDefault: true attr like this :

@Routes([
    {path: '/login', component: LoginComponent,useAsDefault: true}
])
