Error: Template parse errors: The pipe 'filter' could not be found in angular

Question

导入了这个过滤器

// search module
import { Ng2SearchPipeModule } from 'ng2-search-filter';

HTML 代码

//search

<input class="form-control" type="text" name="search" [(ngModel)]="searchText" autocomplete="off" placeholder="search">

//Assigned filter to table

 <tr *ngFor="let bookName of NameOfBookList | filter:searchText">

如有任何帮助，我们将不胜感激。

Answer 1

仅将 Ng2SearchPipeModule 添加到对我有用的导入中。添加到声明时，我的浏览器工具出现错误，指出 Ng2SearchPipeModule.

出现意外声明

@NgModule({
declarations: [
    AppComponent,
    ListComponent
],
imports: [
    BrowserModule,
    FormsModule,
    Ng2SearchPipeModule
],
providers: [],
bootstrap: [AppComponent]
})

然后在我的标记中：

<input [(ngModel)]="term">
...
<tbody *ngFor="let d of myList |filter:term">

Answer 2

我遇到了同样的问题。请在 child childmodule.module.ts.

的导入部分添加 import Ng2SearchPipeModule
