我对react-native和android完全陌生。我已经下载从GitHub项目和使用的命令yarn install，并react-native run-android运行该项目。但出现此错误。似乎无法理解原因。我该怎么办？

问题是该版本正在寻找调试密钥库，但找不到它。
找不到用于签名配置“ debug”的密钥库文件“ / home / tawsif / react native / react-native-redux / android / app / debug.keystore”。
React Native GitHub中存在一个与相同问题有关的问题。根据页面上的内容，您可以通过创建调试密钥库来解决它。从线程引用：
您可以通过在android / app /目录中运行以下命令来生成调试密钥库：keytool -genkey -v -keystore debug.keystore -storepass android -alias androiddebugkey -keypass android -keyalg RSA -keysize 2048 -validity 10000

只需从官方模板https://raw.githubusercontent.com/facebook/react-native/master/template/android/app/debug.keystore下载
复制debug.keystore到您的android/app/.
前任：
mv ~/Downloads/debug.keystore /Users/lazaro/apps/myapp/android/app/
参考：https : //github.com/facebook/react-native/issues/25629#issuecomment-513245590
基于@ rabbit87的答案，解决方案是在ProjectName/Andoid/app目录中运行以下命令
来解决问题
keytool -genkey -v -keystore debug.keystore -storepass android -alias androiddebugkey -keypass android -keyalg RSA -keysize 2048 -validity 10000
我遇到了同样的错误，通过这个https://coderwall.com/p/r09hoq/android-generate-release-debug-keystores解决了
做
cd ./android/app/
进而
keytool -genkey -v -keystore debug.keystore -storepass android -alias androiddebugkey -keypass android -keyalg RSA -keysize 2048 -validity 10000
