应用程序无法编译并出现错误
error NG6001: The class 'NavigationMenuItemComponent' is listed in the declarations of the NgModule 'AppModule', but is not a directive, a component, or a pipe. Either remove it from the NgModule's declarations, or add an appropriate Angular decorator.
当我删除带有参数的构造函数时，错误消失了。
如何在维护具有参数的构造函数的同时解决此问题，因为我想用来初始化组件列表，而不必为列表中的每个成员调用 set 方法
import {
Component,
OnInit
} from '@angular/core';
@Component({
selector: 'app-navigation-menu-item',
templateUrl: './navigation-menu-item.component.html',
styleUrls: ['./navigation-menu-item.component.scss']
})
export class NavigationMenuItemComponent implements OnInit {
static readonly ID_PREFIX: string = 'sidebar-menuitem-';
static readonly ICON_CLASS_PREFIX: string = 'mdi mdi-';
constructor(id: string, iconClass: string) {
this._id = NavigationMenuItemComponent.ID_PREFIX + id;
this._iconClass = NavigationMenuItemComponent.ICON_CLASS_PREFIX + iconClass;
}
//constructor() {}
private _id: string;
private _iconClass: string;
get id() {
return this._id;
}
get iconClass() {
return this._iconClass;
}
set id(id: string) {
this._id = NavigationMenuItemComponent.ID_PREFIX + id;
}
set iconClass(iconClass) {
this._iconClass = NavigationMenuItemComponent.ID_PREFIX + iconClass;
}
ngOnInit(): void {}
}
最佳答案
你必须运行 npm install创建新组件时。热重载似乎无法添加组件。
关于Angular 编译错误 : NG6001: The class is listed in the declarations of the NgModule 'AppModule' , 但不是指令、组件或管道，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/61308517/
