angular - 尝试导入插件之前的完整日历库

问题描述

我在 Angular 9 项目中安装了 FullCalendar 5

然后我在浏览器的控制台中收到此错误，页面中出现任何内容

vdom.js:3 Uncaught Error: Please import the top-level full calendar lib before attempting to import a plugin.

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

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

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

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.scss']
})
export class AppComponent {

  calendarOptions = {
    plugins: [dayGridPlugin],
    initialView: 'dayGridMonth'
  };

}

<full-calendar [options]="calendarOptions"></full-calendar>

解决方案

要解决此问题，您需要在顶部导入日历核心库，然后您需要像这样在构造函数中初始化核心库

import { Component } from '@angular/core';
import { Calendar } from '@fullcalendar/core'; // include this line
import dayGridPlugin from '@fullcalendar/daygrid';

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.scss']
})
export class AppComponent {

  calendarOptions = {
    plugins: [dayGridPlugin],
    initialView: 'dayGridMonth'
  };

 constructor() { 
    const name = Calendar.name; // add this line in your constructor
  }
}
