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张图像（25张以上），但是在尝试访问图库时出现错误。因此，我实际上只有一个按钮，它可以在下面启动此功能，并且我会立即收到错误消息。

这是图像选择器代码：

 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：

方法：'sudo ionic cordova run browser'

错误：

cordova.js：1003错误：找不到:: ImagePicker ::的exec代理:: getPictures home.ts：81 CHEESE缺少命令错误

方法：“ ionic serve”
- 返回错误且不进入图库

故障排除 -删除并重新安装节点模块 -删除并重新安装图像选择器 -确保插件的最新版本 -package.json中已验证的插件 -在iOS和Android上测试 -尝试更改代码，请求权限等。

没有运气。有关检查插件是否已正确安装和配置的更多高级调试。

错误：plugin_not_installed

我一直在寻找替代方案或解决方案，但发现的结论大多过时了。任何建议表示赞赏。我目前正在使用离子本机相机插件来获取图像，但是我的应用程序目的是要上传25张以上的图像，因此单张图像的选择并不理想。

同样，这是我正在使用的离子本机组件和github源码-

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

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

更新：

Xcode模拟器（成功！！！！）我继续为iOS开发了我的应用程序，并在Xcode模拟器上运行了它，哇！有用！

我不确定这是否理想，但至少现在我知道它工作正常。我将继续调试以查看它是否可以达到我的目的并发布更新。

最终更新： 显然，ionic本地图像选择器不能在iOS或Android的ionic dev应用程序上运行，但是可以在Xcode模拟器的生产环境中运行（未经Android模拟器测试，但我确定类似的结果）。由于通过Xcode进行调试非常乏味，因此我将继续从事其他工作。

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

add -    maximumImagesCount: 10
