安装了最新的angular / cli（1.4.2）并使用'ng serve --prod'启动项目

Question

使用'ng serve'启动项目没有问题。 这样的错误信息。

import UIKit

class BubbleImageView: UIImageView {

  var bubbleImage : UIImage? {
    didSet {
      let path = SwipeCard.bubblePath(frame: self.bounds)
      DispatchQueue.global(qos: .background).async {
        //background code
        let newImage = self.createBubbleImage(source: self.bubbleImage, path: path)
        DispatchQueue.main.async {
          //your main thread
          self.image = newImage
        }
      }
    }
  }

  fileprivate func createBubbleImage(source: UIImage?, path: UIBezierPath) -> UIImage? {
    var newImage : UIImage?
    autoreleasepool {
      UIGraphicsBeginImageContextWithOptions(self.bounds.size, false, 0)
      path.addClip()
      source?.draw(in: self.bounds)
      newImage = UIGraphicsGetImageFromCurrentImageContext()
      UIGraphicsEndImageContext()
    }
    return newImage
  }

  deinit {
    bubbleImage = nil
    image = nil
  }

}

在运行npm install之前运行ng serve --prod。在我看来，当AOT踢它时它无法找到动画包。
