"全日历"不是一个已知元素：

Question

嘿，我是Angular的新手。。。到目前为止，我想试试完整的日历。我以前试过运行这个模块，它能正常工作。然而，今天我创建了一个新的项目，并遵循了angular文档中描述的步骤。此外，我完成了fullcalendar文档中的所有步骤，但它仍然不起作用。

这就是我得到的错误：

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>

app.module.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 { }

app.component.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：

Answer 1

看了你的GitHub代码后，我知道它在你帖子中发布的文件中，但由于某种原因，它在你的GitHub:中的app.module.ts中丢失了

import { FullCalendarModule } from '@fullcalendar/angular';

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，你的代码现在就应该可以使用了

Answer 2

也许可以试试这些。。(正如医生所说：https://fullcalendar.io/docs/angular)

npm install --save @fullcalendar/angular @fullcalendar/core @fullcalendar/daygrid

2-(之后在app.module.ts文件中导入模块FullCalendarModule:

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 { }

3-(现在你已经在你的应用程序中有了完整的日历，所以试着在中加入你的组件

a(html

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

b( 在ts中

import { Component } from '@angular/core';
import dayGridPlugin from '@fullcalendar/daygrid'; //< import. it
@Component({
selector: 'app-root',
templateUrl: './app.component.html',
styleUrls: ['./app.component.scss']
})
export class AppComponent {
calendarPlugins = [dayGridPlugin]; // important!
}

4-(小心。。正如医生所说。。。进口css(或scss文件(中的cssMANUALLY放入：

@import '~@fullcalendar/core/main.css';
@import '~@fullcalendar/daygrid/main.css';

希望它能帮助你！！
