角度错误：'Component ' X ' is not included in a module…'在子模块中声明时

提问于

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 .

据我所知，您不必导出组件（仅管道和指令）以在其他模块中使用它们 .

尽管存在此错误，应用程序仍会加载并成功运行 .

Example Component Definition

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();
  }

}

Sub module making Declaration/Export

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';

    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并将compileOnSave设置为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 .

    首先：在 declarations 部分（AppModule）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问题的变体 . 语言服务不正确地遵循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 .

    添加 @angular/language-service 作为dev-dpendency

    要么

    做 npm install @angular/language-service

    可以确认这是在v 5.2.9 中修复的 . YMMV与早期版本 .

    该错误来自Angular语言服务（https://github.com/angular/angular/issues/14961） . 您可以通过清除“设置”|中的“角度语言服务”复选框来禁用它语言和框架|打字稿
