无法从资产“index.android.bundle”加载脚本。请确保包已正确打包或正在运行打包服务器

Question

我正在使用版本为0.38.0的React本机应用程序，当我试图将其升级到0.45.1时，它显示以下错误

java.lang.RuntimeException: Unable to load script from assets 'index.android.bundle'. Make sure your bundle is packaged correctly or you're running a packager server.

我尝试过以下的解决方案，但对我来说并不奏效

SO：无法在Windows上从assets index.android.bundle加载脚本
SO：react native android无法加载JS bundle

Answer 1

1-创建新文件夹=>android/app/src/main/assets
2-运行此命令=>

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

此命令将创建2个文件:index.android.bundle&index.android.bundle.meta

3-运行命令=>react-native run-android
