HostObject :: get中的异常：-React Native Build Android
作者：互联网
将我的React Native应用程序更新为React Native 0.59之后,尝试在调试模式下运行我的应用程序(react-native run-android)或生成软件包并将其安装到设备后,我开始遇到问题.

在我的Metro-bundler加载100％后发生此错误(并且在Bundle Console屏幕上没有发生错误).
谢谢大家的帮助！
解决方法:
该错误是因为您忘记在android中安装某些模块,请检查MainApplication.java,检查是否导入了所有软件包,以及是否将其添加到ReactPackage列表中.
