找不到 Javac [英] Javac is not found

问题描述

I'm running Windows 8 and I can not get javac to work.

I have set my PATH in environmental variables to

C:Program Files (x86)Javajdk1.7.0_17in

I have tried both with and without ';' but to no avail.

I recently had this issue on my desktop and adding ; worked but it's not in this case.

I have made sure that javac does exist in the bin too.

Any suggestions on fixes would be greatly appreciated.

EDITS echo %PATH% gives:

C:UsersArktriDesktop>echo %PATH%

C:Program Files (x86)InteliCLS Client;

C:Program Files (x86)IntelIntel(R) Management Engine ComponentsDAL;
C:Program Files (x86)IntelIntel(R) Management Engine ComponentsIPT;;
C:Program Files (x86)Javajre7in

And the exact error is: 'javac' is not recognized as an internal or external command, operable program or batch file.

解决方案

As far as I can see you have the JRE in your PATH, but not the JDK.

From a command prompt try this:

set PATH=%PATH%;C:Program Files (x86)Javajdk1.7.0_17in

Then try javac again - if this works you'll need to permanently modify your environment variables to have PATH include the JDK too.
