각도 4.4에서 5.0으로 업그레이드 한 후 모든 HttpModule 및 Http를 HttpClientModule로 업데이트 한 후이 오류가 발생하기 시작했습니다.
또한 HttpModule을 다시 추가하여 종속성으로 인한 것이 아니라 문제를 해결하지 못하도록
app.module에서 모두 올바르게 설정했습니다.
import { HttpModule } from '@angular/http';
import { HttpClientModule, HttpClient } from '@angular/common/http';
.
.
.
@NgModule({
imports: [
BrowserModule,
HttpClientModule,
HttpModule,
BrowserAnimationsModule,
FormsModule,
AppRoutingModule,
.
.
.
이 오류가 어디에서 오는지 알 수 없거나 오류를 얻는 방법에 대한 단서가 없습니다. 또한 경고가 있습니다 (아래에 넣으십시오) 관련이있을 수 있습니다.

There are multiple modules with names that only differ in casing.
This can lead to unexpected behavior when compiling on a filesystem with other case-semantic.
Use equal casing. Compare these module identifiers:
