java comand工作但不是javac？ [英] java comand works but not javac?

问题描述

好，所以我有一台新电脑

ok so I got a new PC

Windows 7 Pro 64位Service Pack 1

Windows 7 Pro 64 bit Service Pack 1

jdk-7u25-windows-x64（jdk 1.7.0_25）

I installed jdk-7u25-windows-x64 ( jdk 1.7.0_25)

它安装在默认位置C：\Program Files \Java\jdk1.7.0_25

It is installed in default location C:\Program Files\Java\jdk1.7.0_25

我将JAVA_HOME环境变量设置为C：\Program Files\Java\jdk1.7.0_25

I set the JAVA_HOME environment variable to C:\Program Files\Java\jdk1.7.0_25

我在路径环境变量中添加了％JAVA_HOME％\bin（是的，我使用了;在我添加它之前）

I added %JAVA_HOME%\bin to the Path environment variable (yes I used a ; before I added it)

点击Ok

关闭所有CMD窗口打开它们

Closed all CMD windows opened them up

现在如果我运行命令java我得到预期的输出

And now If I run the command java I get the expected output

但是如果我运行javac命令，我得到这个

But If I run the javac command I get this

C:\Users\AJ>javac
'javac' is not recognized as an internal or external command,
operable program or batch file.

我试过了Fiddling的路径，但没有运气，并重新启动了我的电脑等没有运气

I have tried Fiddling with the path but no luck, and have restarted my PC etc. no luck

如果我在jdk\bin目录中，它似乎也能工作。

Also it seems to work if I am in the jdk\bin directory

C:\>cd C:\Program Files\Java\jdk1.7.0_25\bin

C:\Program Files\Java\jdk1.7.0_25\bin>javac -version
javac 1.7.0_25

C:\Program Files\Java\jdk1.7.0_25\bin>

如何让javac命令正确运行，如java正在执行

how do I get javac command to run correctly like java is doing

推荐答案

我以前对包含空白的路径有问题。我建议更改路径

I had previously problems with the path containing a blank. I would suggest to change the path from

C:\Program Files\Java\jdk1.7.0_25

至

C:\Progra~1\Java\jdk1.7.0_25
