图像选择器 - 离子原生组件

Question

我正在尝试使用this 图像选择器源从设备相机胶卷中选择多个图像（25+），但是当我尝试访问图库时收到错误消息。所以，我基本上只有一个按钮，可以在下面启动这个功能，我会立即收到错误。

这是图片选择器代码：

 private openGallery (): void {
    let options = {
      width: 500,
      height: 500,
      quality: 75
    }

    this.imagePicker.requestReadPermission().then(res=> {
      console.log("res" + res);
      this.imagePicker.getPictures(options).then(
        file_uris => console.log(file_uris),
        err => console.log('CHEESE', err)
      );
    });
  }

以下是控制台记录的错误：

1. 方法：'sudo ionic cordova run browser'

   错误：

cordova.js:1003 错误：找不到执行代理 :: ImagePicker :: getPictures home.ts:81 CHEESE 缺少命令错误

1. 方法：'ionic serve'
   • 返回错误且不进入图库

疑难解答 - 删除并重新安装节点模块 - 删除并重新安装图像选择器 - 确保最新版本的插件 - 在 package.json 中验证插件 - 在 iOS 和 Android 上测试 - 尝试更改代码、请求权限等。

运气不好。接下来检查插件是否正确安装和配置的更高级调试。

错误：plugin_not_installed

这里的版本参考是 package.json

我已经为我的问题寻找替代方案或解决方案，但发现大多是过时的结论。任何建议表示赞赏。我目前正在使用离子原生相机插件来获取图像，但是我的应用程序的目的需要上传 25 多张图像，因此单个图像选择并不理想。

再次，这是我正在使用的离子原生组件和 github 源 -

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

https://github.com/wymsee/cordova-imagePicker

更新：

1. Xcode 模拟器（成功！！！） 我继续为 iOS 构建了我的应用程序并在 Xcode 模拟器上运行它，哇！有用！

我不确定这是否理想，但至少我现在知道它工作正常。我将继续调试，看看它是否能达到我的目的并发布更新。

最终更新： 很明显，离子原生图像选择器不适用于 iOS 或 Android 的 ionic 开发应用程序，但它在 Xcode 模拟器上的生产中工作（未针对 android 模拟器进行测试，但我确信结果相似）。由于通过 Xcode 进行调试很乏味，因此我将从事其他工作。

Answer 1

 let options = {
      width: 500,
      height: 500,
      quality: 75,
      maximumImagesCount: 10
    }

add -    maximumImagesCount: 10
