Question

我已经在模块内创建了组件，并尝试在'app.component.html'中使用简单的html代码输出结果

当我将鼠标悬停在代码上时，会显示此错误“已声明BlogpostModule'，但从不读取它的值。ts（6133）”

当我删除代码“”时。我看到了输出。

请帮助我修复此空白页。

app.component.html

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';

import { AppRoutingModule } from './app-routing.module';
import { BlogpostModule } from './blogpost/blogpost.module';
import { CmspageModule } from './cmspage/cmspage.module';
import { AppComponent } from './app.component';
import { HeaderComponent } from './header/header.component';
import { FooterComponent } from './footer/footer.component';
import { BannerComponent } from './banner/banner.component';
import { PageNotFoundComponent } from './page-not-found/page-not-found.component';


@NgModule({
  declarations: [
    AppComponent,
    HeaderComponent,
    FooterComponent,
    BannerComponent,
    PageNotFoundComponent
  ],
  imports: [
    BrowserModule,
    AppRoutingModule,
    CmspageModule,
    AppRoutingModule
  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule { }

app.module.ts

import { NgModule } from '@angular/core';
import { CommonModule } from '@angular/common';

import { BlogpostRoutingModule } from './blogpost-routing.module';
import { BlogpostFeaturedComponent } from './blogpost-featured/blogpost-featured.component';
import { BlogpostListComponent } from './blogpost-list/blogpost-list.component';
import { BlogpostDetailComponent } from './blogpost-detail/blogpost-detail.component';
import { BlogpostRecentComponent } from './blogpost-recent/blogpost-recent.component';
import { CategoriesComponent } from './categories/categories.component';


@NgModule({
   imports: [
    CommonModule,
    BlogpostRoutingModule
  ],
  exports: [
    BlogpostFeaturedComponent
  ],
  declarations: [BlogpostFeaturedComponent, BlogpostListComponent, BlogpostDetailComponent, BlogpostRecentComponent, CategoriesComponent],
  })
export class BlogpostModule { }

blogpost.module.ts

results_index = [
    {'p': 2, 'q': 7},
    {'p': 2, 'q': 5},
    {'p': 1, 'q': 4},
    {'p': 2, 'q': 4}
]

results_data = [
    {'A': 0.18, 'B': 0.18},
    {'A': 0.67, 'B': 0.21},
    {'A': 0.96, 'B': 0.45},
    {'A': 0.58, 'B': 0.66}
]

index = pd.MultiIndex.from_frame(pd.DataFrame(results_index))

pd.DataFrame(results_data, index=index)

您忘记在BlogpostModule中加入app.module.ts。

为什么模块的Import export给出错误，因为声明了“ BlogpostModule”，但其值从未读取。ts（6133）” angular 7
