angular - “全日历”不是已知元素 :

Question

嘿，我是 Angular 的新手...到目前为止，我想试用完整日历。我之前尝试运行该模块并且它有效。然而，今天我创建了一个新项目，并按照 Angular 文档中描述的步骤进行操作此外，我完成了完整日历文档中的所有步骤，但它仍然无法正常工作。

这是我遇到的错误:

ERROR in src/app/app.component.html:1:1 - error NG8001: 'full-calendar' is not a known element:
1. If 'full-calendar' is an Angular component, then verify that it is part of this module.
2. If 'full-calendar' is a Web Component then add 'CUSTOM_ELEMENTS_SCHEMA' to the '@NgModule.schemas' of this component to suppress this message.

1 <full-calendar defaultView="dayGridMonth" [plugins]="calendarPlugins"></full-calendar>

应用程序模块.ts

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import {FullCalendarModule} from '@fullcalendar/angular';
import { AppComponent } from './app.component';

@NgModule({
  declarations: [
    AppComponent
  ],
  imports: [
    BrowserModule,
    FullCalendarModule
  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule { }

应用程序组件.ts

import { Component } from '@angular/core';
import dayGridPlugin from '@fullcalendar/daygrid';

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent {
  title = 'nachweis-frontend';
  calendarPlugins = [dayGridPlugin];
}

app.component.html

<full-calendar [plugins] = "calendarPlugins"></full-calendar>

这也是我的 Angular json。我在这里没有做任何更改:

查看您的 GitHub 代码后，我知道它在您发布的文件中，但出于某种原因，它在您的 GitHub 中的 app.module.ts 中丢失了:

从“@fullcalendar/angular”导入 { FullCalendarModule}；

和

imports: [
    BrowserModule,
    FullCalendarModule
],

我在我的机器上测试了它，所以只要你安装了 package.json 中的所有 npm 包，你的代码现在应该可以工作了
