error screnshot

'"/Users/dev/pratice_workspace/quickstart/src/app/components/language.component"' has no exported member 'LangugeComponent'. import LangugeComponent

錯誤的鉻控制檯

ZoneAwareError __zone_symbol__error : Error: (SystemJS) Unexpected value 'undefined' declared by the module 'AppModule' Error: Unexpected value 'undefined' declared by the module 'AppModule' at SyntaxError.ZoneAwareError (

應用。 module.ts

import { NgModule } from '@angular/core'; 
import { BrowserModule } from '@angular/platform-browser'; 
import { AppComponent } from './app.component'; 
import { LangugeComponent } from './components/language.component'; 
@NgModule({ 
    imports: [BrowserModule], 
    declarations: [AppComponent, LangugeComponent], 
    bootstrap: [AppComponent] 
}) 
export class AppModule {} 

language.component.ts

import { Component } from '@angular/core'; 
@Component({ 
    selector: 'language', 
    template: ` 
    <h1>Hello</h1> 

    `, 
}) 
export class LanguageComponent { 
    name = 'Sandeep'; 
    designation = 'SE' 
}

看起來你有app.module.ts

import { LangugeComponent } from './components/language.component' 

declarations: [AppComponent, LangugeComponent]` 

錯字應

import { LanguageComponent } from './components/language.component' 

declarations: [AppComponent, LanguageComponent]`
