react-native - react native 签名的 APK 崩溃

Question

启动后签名的 APK 崩溃，在 logCat 中我得到了 requiring unknown module 'React'
调试应用程序工作正常，但在 logCat 中我得到 >> 仅支持按名称要求模块“React”，并且将在生产中中断!

react v15.4.1， react 原生 v0.39.2 ？

对不起我的英语不好

import myapp from './index_start.js';

AppRegistry.registerComponent('myapp', () => myapp);
