我有一个用react native init myapp初始化的React Native项目（不是Expo）。我可以在Android 5的Emulator和Real Device上运行此应用程序，但无法在Android 8的Android Mobile上运行该应用程序。
这是package.json：

我已经在Android 5的Genymotion模拟器和Android 5的真实LG设备上进行了测试，一切正常。
但是最近，我尝试在一台采用Android 8的Honor 8X设备上运行这个项目。但是在从Metro收到JS Bundle之后，该应用程序将被关闭而没有任何错误！
react-native run-android这是来自react-native log-android的日志：

在最后一行出现后，应用程序将在设备上关闭！
这是Metro Bundler输出（看起来很好）：

myapp在Android 5的Emulator和Device上运行成功，我完全糊涂了...... Maby有一个问题与依赖关系环境： - Windows 10企业版

你有没有尝试清除缓存？通常用这样的东西：
rm package-lock.json
rm -rf node_modules
rm -rf $TMPDIR/metro-*
rm -rf $TMPDIR/haste-map-*
npm cache clean
npm install
npm start -- --reset-cache
但是您可能只需要删除metro和急速地图缓存。对不起，如果你已经尝试过了。
我遇到了与小米和现实相同的问题。
开始测试moto设备工作正常。
看起来反应原生的v0.58.0与现在不兼容/破坏了一些东西;临时解决方案是使用v0.57.8初始化您的RN项目
步骤：react-native init --version =“[email protected]”projectName cd projectName npm install realm --save react-native link
它应该工作
