我是 Ionic 的新手，正在尝试构建具有离线支持的移动应用程序。我正在尝试使用cordova sqlite插件创建数据库。我可以在模拟器的data\data\package\data.db. 无法执行任何插入语句。

import { Component } from '@angular/core';
import { NavController, Platform } from 'ionic-angular';
import { SQLite, SQLiteObject } from '@ionic-native/sqlite';

@Component({
  selector: 'page-home',
  templateUrl: 'home.html'
})
export class HomePage {
  dbHandle : SQLiteObject;
  constructor(public navCtrl: NavController, private sqlite: SQLite, public plt: Platform) {
    this.plt.ready().then((readySource) => {
      console.log('Platform ready from', readySource);
      // Platform now ready, execute any required native code
      this.handleDbCreation(); 
    });

  }

  handleDbCreation() {
    this.sqlite.create({
      name: 'data.db',
      location: 'default'
    }).then((db: SQLiteObject) => {
      this.dbHandle = db;
      db.executeSql('create table danceMoves(name VARCHAR(32))', {})
        .then(() => {console.log('Executed SQL')
          this.insertDataIntoDB();
        })
        .catch(e => console.log(e));
    }).catch(e => console.log(e));
  }

  insertDataIntoDB(){
    this.dbHandle.executeSql("insert into danceMoves values(?)",['testing'])
    .then((resultSet)=>{
        console.log('resultSet.insertId: ' + resultSet.insertId);
        console.log('resultSet.rowsAffected: ' + resultSet.rowsAffected);
    })
    .catch((error)=>{
       console.log('SELECT error: ' + error.message);
    });  
  }
}

我收到下面提到的错误。
