我刚刚搭建了我的第一个ionic 2应用程序（我之前已经广泛使用过ionic 1）。我正在尝试使用ionic-native camera 预览插件。
设置过程非常简单：
npm install -g ionic cordova
ionic start timesnap --v2
ionic platform add android
ionic platform add ios
ionic plugin add cordova-plugin-camera-preview --save
然后我复制并粘贴示例代码到关于页面：
import { CameraPreview, CameraPreviewRect } from 'ionic-native';
// camera options (Size and location)
let cameraRect: CameraPreviewRect = {
x: 100,
y: 100,
width: 200,
height: 200
};
// start camera
CameraPreview.startCamera(
cameraRect, // position and size of preview
'front', // default camera
true, // tap to take picture
false, // disable drag
true, // send the preview to the back of the screen so we can addoverlaying elements
1 //alpha
);
我使用以下命令启动了这个应用：
ionic emulate android -lcs
ionic emulate ios -lcs --target='iPhone-6'
chrome://inspect，看到了有关Cordova缺少“尝试在模拟器中运行”的警告，但这是在Android模拟器上运行时出现的。我也尝试了iOS，并看到了相同的结果。有什么想法为什么Cordova无法加载？
以下是在Android模拟器中运行时从
chrome://inspect获取的完整错误日志：

-l)，它似乎可以正常工作。不确定这是否是预期的，但我在他们的 GitHub 上提出了一个问题。如果这是预期的，它应该在文档中说明。 - Lenny
