Javascript Android:JS捆绑包未从Metro捆绑服务器加载

在Android上，我突然无法让metro bundler服务器工作。在过去的5个小时里，我一直在调试这个问题，但我找不到导致这个问题的任何原因。与问题中的不同，我的应用程序甚至没有开始显示日志框红色错误警告。它马上就崩溃了

每当我尝试运行Android应用程序时（我尝试过各种不同的设置，启用/禁用Hermes，ABI拆分，显式强制一个SoLoader版本，剥离各种代码以获得最小的应用程序，清理gradle缓存，将

Android:useClearTextTraffic=“true”

添加到我的

AndroidManifest.xml

，等等…），该应用程序以白屏启动，随后立即崩溃。我在Logcat中找到了一些异常：

当我手动创建JS包时，请使用以下命令：

npx react native bundle--platform android--dev false--entry file index.js--bundle output android/app/src/main/assets/index.android.bundle--assets dest android/app/src/main/res

我成功地通过Android Studio启动了应用程序，但这当然不是一个解决方案，因为每次我更改某些内容时都必须运行此命令（即使在JS中），因此我不再有实时重新加载，也没有

控制台.log

了，而且我的开发体验很糟糕

简而言之：不知何故，我的应用程序无法在

localhost

上的metro bundler服务器上传输捆绑包，但当我手动创建捆绑包时，它就可以工作了。它甚至没有启动地铁捆绑机！在iOS上它可以工作。

所以这是一个依赖性问题。如果其他人遇到这个问题，请将您的项目与“模板”项目（在react native repo中）进行比较，尤其是查看package.json中的所有版本！对我来说，我有metro配置0.65，这对于RN 0.63来说太新了
