Angular2 Error: Cannot match any routes. URL Segment:

I'll try to explain what's going wrong and what can we do to solve this.

#1: '' route is being redirected to more than 1 routes. It creates an ambiguity, the Angular router fails to decide where to redirect to. I'll assume '' needs to redirect to '/jobs'.

#2: A route definition with loadChildren shouldn't contain component property.

#3: Misuse of FullLayoutComponent as a template. You can use AppComponent to be bootstrapped by the Angular app, use a router-outlet in app.component.html and have your template working.

Try to fix your file/dir structure and fix your module code explained as below.

file/dir structure:

|- app.module.ts
|- app.component.ts (copy the ../layouts/full-layout.component into this file)
|- job\
    |- job.module.ts
    |- jobfile\
        |- jobfile.module.ts
    |- jobcompleted\
        |- jobcompleted.module.ts

job.module

import { NgModule } from '@angular/core`;
import { Routes, RouterModule } from '@angular/router';
import { JobComponent } from './job.component';

const jobRoutes: Routes = [
    {
        path: '',
        component: JobComponent,
        data: {title: 'Job Assignment' },
    }
];

@NgModule({
    declarations: [
        JobComponent
    ],
    imports: [
        RouterModule.forChild(jobRoutes)
    ]
})
class JobModule { }

jobfile.module

import { NgModule } from '@angular/core`;
import { Routes, RouterModule } from '@angular/router';
import { JobfileComponent } from './jobfile/jobfile.component';

const jobFileRoutes: Routes = [
    {
        path: '',
        component: JobfileComponent,
        data: {title: 'Job File' },
    }
];

@NgModule({
    declarations: [
        JobfileComponent
    ],
    imports: [
        RouterModule.forChild(jobFileRoutes)
    ]
})
class JobFileModule { }

jobcompleted.module

import { NgModule } from '@angular/core`;
import { Routes, RouterModule } from '@angular/router';
import { JobcompletedComponent } from './jobcompleted/jobcompleted.component';

const jobCompletedRoutes: Routes = [
    {
        path: '',
        component: JobcompletedComponent,
        data: {title: 'Job File' },
    }
];

@NgModule({
    declarations: [
        JobcompletedComponent
    ],
    imports: [
        RouterModule.forChild(jobCompletedRoutes)
    ]
})
class JobCompletedModule { }

app.module

import { NgModule } from '@angular/core`;
import { Routes, RouterModule } from '@angular/router';
// OTHER IMPORTS
// ...
import { AppComponent } from './app.component.ts';

const routes: Routes = [
    { path: 'job', loadChildren: './job/job.module#JobModule' }
    { path: 'jobfile', loadChildren: './job/jobfile/jobfile.module#JobfileModule' }
    { path: 'jobcompleted', loadChildren: './job/jobcompleted/jobcompleted.module#JobcompletedModule' }
    { path: '', redirectTo: 'job', pathMatch: 'full' },
];

@NgModule({
    declarations: [
        // OTHER COMPONENTS
        // ...
        AppComponent
    ],
    imports: [
        // OTHER MODULES
        // ...
        RouterModule.forRoot(routes)
    ],
    // PROVIDERS, ETC ADD BELOW
    // ...
    bootstrap: [AppComponent]
})
class AppModule { }

And finally, you'll need to provide app.component.ts and app.component.html. Basically, copy the core from your FullLayoutComponent to update these files.

Make sure that you include <router-outlet></router-outlet> in your app.component.html. This outlet will be used by Angular router to render the contents of your JobComponent, JobfileComponent, JobcompletedComponent.

Hope the answer is helpful, happy Angular'ing ;)
