找不到Javac [英] Javac is not found

问题描述

我运行Windows 8，我不能让javac工作。

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

我已将环境变量中的PATH设置为

I have set my PATH in environmental variables to

C：\Program文件（x86）\Java\jdk1.7.0_17\bin

我尝试过和没有';'徒劳无功。

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

我最近在我的桌面上有这个问题，并添加;工作，但不是在这种情况下。

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

我已经确定javac确实存在于bin中。

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

我们非常感谢您对修正建议。

Any suggestions on fixes would be greatly appreciated.

C:\Program Files (x86)\Intel\Intel(R) Management Engine Components\DAL;
C:\Program Files (x86)\Intel\Intel(R) Management Engine Components\IPT;;
C:\Program Files (x86)\Java\jre7\bin

确切的错误是：'javac'不被识别为内部或外部命令，可操作的程序或批处理文件。

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

推荐答案

就我所见，你在 PATH 中有 JRE ，而不是 JDK 。

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

从命令提示符尝试：

set PATH=%PATH%;C:\Program Files (x86)\Java\jdk1.7.0_17\bin

然后再次尝试 javac - 如果这个工作，你将需要永久修改你的环境变量以具有 PATH 也包括 JDK 。

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