我有一个使用 RN 0.49.5 开发的 react 本机应用程序。我不得不将它升级到最新的 react-native 版本（现在是 0.59.5）。
虽然我在开发模式下运行它时遇到问题。有趣的是，如果我为发布（cd android && ./gradlew assembleRelease）构建它，它工作正常。应用程序一启动就崩溃，logcat 显示以下错误：

Make sure that you have rebuilt the native code. If the problem persists try clearing the watchman and packager caches with `watchman watch-del-all && react-native start --reset-cache`., stack:
