类型{static：Boolean；}的参数不能赋值给类型{read？：any}的参数

Question

在我新创建的Angular应用程序中，我尝试使用mattlewis92的Angular日历来创建他的日历。我已经复制了他的github:https://mattlewis92.github.io/Angulat-calendar/#/kitchenter-sink上列出的所有步骤和代码，但我在第一行总是发现一个错误，即@viewchild('modal content',{static：true}）modalcontent:templateRef ； 指出“{static：boolean；}类型的参数不能分配给{read？：any}类型的参数”。下面是代码的其余部分以供参考，但我认为这并不重要：

import { Component, ChangeDetectionStrategy, ViewChild, TemplateRef} from '@angular/core';
import { startOfDay, endOfDay, subDays, addDays, endOfMonth, isSameDay, isSameMonth, addHours } from 'date-fns';
import { Subject } from 'rxjs';
import { NgbModal } from '@ng-bootstrap/ng-bootstrap';
import { CalendarEvent, CalendarEventAction, CalendarEventTimesChangedEvent, CalendarView } from 'angular-calendar';

import * as _moment from 'moment';
import { JQ_TOKEN } from '../common/jQuery.service';
const moment = _moment;

const colors: any = {
  red: {
    primary: '#ad2121',
    secondary: '#FAE3E3'
  },
  blue: {
    primary: '#1e90ff',
    secondary: '#D1E8FF'
  },
  yellow: {
    primary: '#e3bc08',
    secondary: '#FDF1BA'
  }
};

@Component({
  selector: 'vacation',
  changeDetection: ChangeDetectionStrategy.OnPush,
  templateUrl: './vacation.component.html',
  styleUrls: ['./vacation.component.css']
})

export class VacationComponent {
  @ViewChild('modalContent', { static: true }) modalContent: TemplateRef<any>;

  view: CalendarView = CalendarView.Month;

  CalendarView = CalendarView;

  viewDate: Date = new Date();

  modalData: {
    action: string;
    event: CalendarEvent;
  };

  actions: CalendarEventAction[] = [
    {
      label: '<i class="fa fa-fw fa-pencil"></i>',
      onClick: ({ event }: { event: CalendarEvent }): void => {
        this.handleEvent('Edited', event);
      }
    },
    {
      label: '<i class="fa fa-fw fa-times"></i>',
      onClick: ({ event }: { event: CalendarEvent }): void => {
        this.events = this.events.filter(iEvent => iEvent !== event);
        this.handleEvent('Deleted', event);
      }
    }
  ];

  refresh: Subject<any> = new Subject();

  events: CalendarEvent[] = [
    {
      start: subDays(startOfDay(new Date()), 1),
      end: addDays(new Date(), 1),
      title: 'A 3 day event',
      color: colors.red,
      actions: this.actions,
      allDay: true,
      resizable: {
        beforeStart: true,
        afterEnd: true
      },
      draggable: true
    },
    {
      start: startOfDay(new Date()),
      title: 'An event with no end date',
      color: colors.yellow,
      actions: this.actions
    },
    {
      start: subDays(endOfMonth(new Date()), 3),
      end: addDays(endOfMonth(new Date()), 3),
      title: 'A long event that spans 2 months',
      color: colors.blue,
      allDay: true
    },
    {
      start: addHours(startOfDay(new Date()), 2),
      end: new Date(),
      title: 'A draggable and resizable event',
      color: colors.yellow,
      actions: this.actions,
      resizable: {
        beforeStart: true,
        afterEnd: true
      },
      draggable: true
    }
  ];

  activeDayIsOpen: boolean = true;

  constructor(private modal: NgbModal) { }

  dayClicked({ date, events }: { date: Date; events: CalendarEvent[] }): void {
    if (isSameMonth(date, this.viewDate)) {
      this.viewDate = date;
      if (
        (isSameDay(this.viewDate, date) && this.activeDayIsOpen === true) ||
        events.length === 0
      ) {
        this.activeDayIsOpen = false;
      } else {
        this.activeDayIsOpen = true;
      }
    }
  }

  eventTimesChanged({
    event,
    newStart,
    newEnd
  }: CalendarEventTimesChangedEvent): void {
    this.events = this.events.map(iEvent => {
      if (iEvent === event) {
        return {
          ...event,
          start: newStart,
          end: newEnd
        };
      }
      return iEvent;
    });
    this.handleEvent('Dropped or resized', event);
  }

  handleEvent(action: string, event: CalendarEvent): void {
    this.modalData = { event, action };
    this.modal.open(this.modalContent, { size: 'lg' });
  }

  addEvent(): void {
    this.events = [
      ...this.events,
      {
        title: 'New event',
        start: startOfDay(new Date()),
        end: endOfDay(new Date()),
        color: colors.red,
        draggable: true,
        resizable: {
          beforeStart: true,
          afterEnd: true
        }
      }
    ];
  }

  deleteEvent(eventToDelete: CalendarEvent) {
    this.events = this.events.filter(event => event !== eventToDelete);
  }

  setView(view: CalendarView) {
    this.view = view;
  }

  closeOpenMonthViewDay() {
    this.activeDayIsOpen = false;
  }
}

如果有任何帮助，我将非常感谢为什么会发生这种情况，或者我将如何解决它？

一旦你升级到新版本的Angular。删除node_module文件夹并运行NPM Install
