Angular 如何在ionic4中使用“选择”从“离子角度”导入

我想使用“ionic angular”中的import{Select}以编程方式打开ionic Select组件

以前的线程使用了导入，但ionic 4在“ionic angular”或“@ionic/angular”中未检测到“select”

我试着用“@ionic angular”替换“ionic angular”

import { Component, OnInit, ViewChild} from '@angular/core';
import { PopoverController } from '@ionic/angular';
import { ValidEstatesPage } from '../valid-estates/valid-estates.page';
import {Select} from '@ionic/angular';



@Component({
  selector: 'app-otp',
  templateUrl: './otp.page.html',
  styleUrls: ['./otp.page.scss'],
})
export class OtpPage implements OnInit {

  SelectOption: boolean;
  value = 0;
  @ViewChild('popSelect') selectPop: Select;
  constructor(private popoverController: PopoverController, p) {
    this.SelectOption = false;
  }
  submitOTP(): void {

    this.SelectOption = true;
  }

   async openPopover(ev: Event) {
    const popover = await this.popoverController.create({
      component: ValidEstatesPage,
      componentProps: {
        custom_id: this.value
      },
      ev: ev
    });
    popover.present();
  }

  resendOTP(): void {

  }
  ngOnInit() {
  }

因此，您的导入应该如下所示：

从'@ionic/angular'导入{IonSelect}； // ... @查看子项“popSelect”选择POP:IonSelect； // ... 此选项为.selectPop.open；
