ionic3 - Object(...) 不是 WheelSelector.show 的函数

问题描述

下面是我的 package.json 文件：

"@angular/common": "5.2.11",
"@angular/compiler": "5.2.11",

我想在我的应用程序中实现 wheelselector，因此我使用了以下指南： https ://ionicframework.com/docs/v3/native/wheelselector-plugin/

在 .html 文件中，我创建了一个离子按钮，并在单击时调用该函数以显示选择器：

jsonData = { ......... }

   selectANumber() {
    this.selector.show({
    title: "How Many?",
    items: [
     this.jsonData.numbers
    ],
   }).then(
   result => {
    console.log(result[0].description + ' at index: ' + 
   result[0].index);
  },
  err => console.log('Error: ', err)
  );
}

但不幸的是得到了错误。

解决方案

如果您使用的是 ionic 3，请尝试降级到插件的 v4。

$ npm install --save @ionic-native/wheel-selector@4

并且在导入插件时不要添加/ngx 。这应该有效。
