Ionic 3应用程序在iOS设备上运行缓慢: ionic cordova build ios --prod --aot

Question

目前，我正在做一个项目，是Ionic 3。我需要在iOS设备上部署应用程序。但这款应用在iOS设备上运行速度非常慢。我试着运行这个命令ionic cordova build ios --prod --aot。但它导致了一堆离子组件错误。

使用prod和aot应用程序构建时的错误屏幕截图：

你还有这个问题吗？

如果是，那么尝试卸载所有插件，清理您的项目，然后重新安装所有以前删除的插件。确保每个插件都安装了正确的依赖项(并且在正确的版本中)。

就我个人而言，我不知道是否有快速卸载/重新安装所有东西的方法，但这实际上可能会加快应用程序的运行速度，并可能解决不一致问题，因此绝对值得尝试(如果你还没有尝试)。

希望能有所帮助！
