角度误差:当在子模块中声明时,'组件'X'不包含在模块中......

Question

我正在尝试将我的对话框合并到一个Angular模块中,但是我在IDE中遇到了一个linting错误:

组件"X"未包含在模块中,并且在模板内不可用.考虑将其添加到NgModule声明中.

尽管存在此错误,应用程序仍会加载并成功运行.

示例组件定义

import { Component, Inject, OnInit, ViewEncapsulation } from '@angular/core';
import { MAT_DIALOG_DATA, MatDialogRef } from '@angular/material';

export interface AlertDialogData {
  titleText: string;
  dismissalText: string;
  contentComponent: string;
}

@Component({
  selector: 'app-alert-dialog',
  templateUrl: './alert-dialog.component.html',
  styleUrls: ['./alert-dialog.component.scss'],
  encapsulation: ViewEncapsulation.None
})
export class AlertDialogComponent implements OnInit {

  constructor(private dialogRef: MatDialogRef<AlertDialogComponent>, @Inject(MAT_DIALOG_DATA) public data: any) { }

  ngOnInit() {
  }

  handleCloseClick(): void {
    this.dialogRef.close();
  }

}

子模块制作声明/导出

import { CUSTOM_ELEMENTS_SCHEMA, NgModule } from '@angular/core';
import { CommonModule } from '@angular/common';
import { ZipLocatorDialogComponent } from './zip-locator-dialog/zip-locator-dialog.component';
import { AlertDialogComponent } from './alert-dialog/alert-dialog.component';
import { HelperDialogComponent } from './helper-dialog/helper-dialog.component';
import {
  MatAutocompleteModule, MatButtonModule, MatDialogModule, MatFormFieldModule, MatInputModule,
  MatSelectModule
} from '@angular/material';
import { FlexLayoutModule } from '@angular/flex-layout';
import { FormsModule, ReactiveFormsModule } from '@angular/forms';

@NgModule({
  imports: [
    CommonModule,
    FlexLayoutModule,
    FormsModule,
    ReactiveFormsModule,
    MatDialogModule,
    MatInputModule,
    MatFormFieldModule,
    MatSelectModule,
    MatAutocompleteModule,
    MatButtonModule
  ],
  exports: [
    ZipLocatorDialogComponent,
    HelperDialogComponent,
    AlertDialogComponent
  ],
  declarations: [
    ZipLocatorDialogComponent,
    HelperDialogComponent,
    AlertDialogComponent
  ],
  entryComponents: [
    ZipLocatorDialogComponent,
    HelperDialogComponent,
    AlertDialogComponent
  ],
  schemas: [
    CUSTOM_ELEMENTS_SCHEMA
  ]
})
export class AppDialogsModule { }

Answer 1

我有同样的问题,这是如何解决的:

1)转到Intellij/IDE设置并勾选(设置)对以下更改的重新编译:

2)转到tsconfig.json并设置compileOnSave为true:

现在去除导致问题的@Component,并重新键入@Component.

这对我有用:)祝你好运.

Answer 2

如果您使用的是 IntelliJ IDE（我正在运行 WebStorm），请尝试以下操作：

文件 -> 使缓存无效/重新启动 -> 无效并重新启动

它应该修复该FooComponent is not declared in any Angular module错误。

Answer 3

首先：在声明部分 ( app.module.ts) 中声明所有组件。

如果问题仍然存在，我记得这是 beta angular-cli 版本的问题。

您遇到的问题是 baseUrl 问题的一个变体。语言服务没有正确遵守 baseUrl 选项。例如，如果您将共享模块的导入从 app/shared/shared.module 更改为 ../shared/shared.module 那么错误就会消失。
