我使用图像选择器从图库中选择多个图像，但我得到了“Plugin_not_installed”

我使用 From 链接安装插件离子图像选择器

ionic cordova plugin add cordova-plugin-telerik-imagepicker
npm install @ionic-native/image-picker

在我的 package.json 中安装 cordova 插件和 telerik 图像选择器后：

}

并使用图像选择器

 let options: ImagePickerOptions = {
      maximumImagesCount: 8
    };`enter code here`
if( !this.imagePicker.hasReadPermission) this.imagePicker.requestReadPermission();

    this.imagePicker.getPictures(options).then((results) => {
      for (var i = 0; i < results.length; i++) {
          console.log('Image URI: ' + results[i]);
      }
    }, (err) => {alert(err) });

并用于运行 ionic serve --devapp

当点击 getImage 我使用警报获取错误

"Plugin_not_installed"

并在 vsCode 控制台中

`[ng] [console.warn]: "Native: tried calling ImagePicker.getPictures, but the ImagePicker plugin is not installed."
[ng] [console.warn]: "Install the ImagePicker plugin: 'ionic cordova plugin add cordova-plugin-telerik-imagepicker'"`

网上所有的例子都是这样做的

我也测试命令

npm install @ionic-native/image-picker@4

用于安装版本 4 但应用程序未构建。

我的离子版本是 4，我运行 android 平台

4

您可以使用

https://ionicframework.com/docs/native/image-picker

ionic cordova plugin add cordova-plugin-telerik-imagepicker
npm install @ionic-native/image-picker

 * `cordova plugin add cordova-android-support-gradle-release`
 * `ioinc cordova platform rm android`
 * `ionic cordova platform add android`
 * `ionic cordova build android --prod`


import { ImagePicker, ImagePickerOptions } from '@ionic-native/image-picker/ngx';


constructor(private imagePicker: ImagePicker) { }




getPictures() {
    let options: ImagePickerOptions = {  
          //here Quality of images, defaults to 100  
          quality: 100,  
          //here Width of an Image  
          width: 600,  
          //here Height of an Image  
          height: 600,  
          /** Output type, defaults to 0 (FILE_URI). 
    
          * FILE_URI :0 (number) it returns a actual path for an image 
    
          */  
          
          outputType: 1  
          //here Maximum image count for selection, defaults to 15.  
          //while setting a number 15 we can load 15 images in one selection.
    
          maximumImagesCount: 8
          // max images to be selected, defaults to 15. If this is set to 1  
        }; 
    
     this.imagePicker.getPictures(options)
          .then(selectedImg => { })
    }

尝试以非本地方式使用插件。在您的组件中声明一个窗口变量，然后使用它来调用插件。您需要从设备上对其进行测试，它不能在浏览器上运行，也不能在 --devapp serve 上运行。它可以正常工作，但它没有使用选项对象......我需要它返回 base64（输出类型：1），但总是返回 fileURI

/*Imports section*/

declare const window: any;

@Component({...})

export class HomePage implements OnInit {

 constructor(){}

 yourMethod() {
  window.imagePicker.getPictures(
    async function(results) {
      for (var i = 0; i < results.length; i++) {
        const currentPicture = results[i];
        files.push(currentPicture);
      }
      console.log(files);
    }, function (error) {
      console.log('Error: ' + error);
    },
    {
      outputType: 1,
      maximumImagesCount: 30,
      quality: 100
    }
  );
 }
}
