英文:
react native does not identify java JDK
问题
我目前正在开发一个原生应用程序。但是当我尝试启动应用程序时，npx给了我一个错误。
JAVA_HOME设置为无效目录：/usr/lib/jvm/java-8-openjdk-amd64

这只发生在react-native中。当我编译一个Java文件或运行Android应用程序时，我不会遇到任何关于找不到JDK的问题。
我的JAVA_HOME是
/usr/lib/jvm/java-8-openjdk-amd64

This is only happens with react-native. When I compile a java file or run android application I don't get any problems with finding JDK.
my JAVA_HOME is
/usr/lib/jvm/java-8-openjdk-amd64
