Question

我在Ionic 4中有一个项目正在尝试使用SQLite数据库：

      this.sqlite.create({
        name: 'ionicdb.db',
        location: 'default'
      }).then((db: SQLiteObject) => {

        db.executeSql('CREATE TABLE IF NOT EXISTS table1 (id INTEGER PRIMARY KEY AUTOINCREMENT NOT NULL UNIQUE, title TEXT)').then(a=> console.log('success'));
    });
});

我试图在设备上运行以上代码。数据库已成功创建/打开，但是executeSql调用引发以下错误：

vendor.js:51623 ERROR Error: Uncaught (in promise): TypeError: window.angular.element is not a function

任何想法为什么会发生这种情况？谢谢！

TypeError：window.angular.element不是Ionic 4 SQLite中的函数
