Whether all configured system variables
CodePudding user response:
Java, javac not
The easiest way to think of javac file damage or environment variable configuration errors,
But in fact, the biggest possibility is to install any other written in Java software, software changed the environment variable (set up the Java command)
But there is no javac
Did you see on the computer to AE, ERP, software, such as these will change the environment variables, give a person a kind of illusion, Java is ready to run, seems to have half the success, but in fact there is no configuration is successful,
