java 命令有效但 javac 无效? [英] java comand works but not javac?

问题描述

好的，所以我买了一台新电脑

ok so I got a new PC

Windows 7 专业版 64 位服务包 1

Windows 7 Pro 64 bit Service Pack 1

我安装了 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 FilesJavajdk1.7.0_25

It is installed in default location C:Program FilesJavajdk1.7.0_25

我将 JAVA_HOME 环境变量设置为 C:Program FilesJavajdk1.7.0_25

I set the JAVA_HOME environment variable to C:Program FilesJavajdk1.7.0_25

我在 Path 环境变量中添加了 %JAVA_HOME%in(是的，我在添加之前使用了 ;)

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

点击确定

关闭所有的 CMD 窗口打开它们

Closed all CMD windows opened them up

现在如果我运行命令 java 我会得到预期的输出

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

但是如果我运行 javac 命令，我会得到这个

But If I run the javac command I get this

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

我试过摆弄路径但没有运气，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 jdkin 目录中，它似乎也可以工作

Also it seems to work if I am in the jdkin directory

C:>cd C:Program FilesJavajdk1.7.0_25in

C:Program FilesJavajdk1.7.0_25in>javac -version
javac 1.7.0_25

C:Program FilesJavajdk1.7.0_25in>

如何让 javac 命令像 java 一样正确运行

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

推荐答案

我之前遇到过路径包含空白的问题.我建议从

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

C:Program FilesJavajdk1.7.0_25

到

C:Progra~1Javajdk1.7.0_25
