Question

我有一个使用RN 0.49.5开发的react本机应用程序。我必须将其升级到最新的本机版本（现在为0.59.5）。

尽管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，则可以正常工作。该应用程序一启动就会崩溃，并且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:

关闭所有node terminals。这通常意味着您有一些运行本机的终端。我建议只使用restart这台计算机，这将是最简单的。

如果这不起作用，请尝试delete您的/node_modules文件夹并在终端中执行：

 1. npm cache verify
 2. npm install

然后使用您的react-native run-android命令。
