javac 无法识别 java 7 [英] javac not recognized java 7

问题描述

我最近在我的 windows vista 上安装了 jdk7.我在 C:Program FilesJavajdk1.7.0_02 中使用了默认安装，javac 存储在 C:Program FilesJavajdk1 中.7.0_02in.我已经用 C:Program_FilesJavajdk1.7.0inPATH 和 CLASSPATH 环境变量(对于我的用户和系统变量)code> 和 JAVA_HOME(作为我的用户变量)与 C:Program_FilesJavajdk1.7.0(我也尝试过一个带有 C:Program_FilesJavajdk1.7.0_02in).

I have recently installed jdk7 on my windows vista. I have used default installation in C:Program FilesJavajdk1.7.0_02 with javac stored in C:Program FilesJavajdk1.7.0_02in. I have configured my PATH and CLASSPATH environmental variables (both for my user and system variables) with C:Program_FilesJavajdk1.7.0in and JAVA_HOME (as my user variable) with C:Program_FilesJavajdk1.7.0 (I have also tried a version with C:Program_FilesJavajdk1.7.0_02in).

java -version 产生所需的输出.我也可以从 C:Program_FilesJavajdk1.7.0in 目录运行 javac 没有问题.但是，当我尝试从其他地方运行它时，出现无法识别的错误.问题出在哪里.我错过了什么吗?

java -version produces desired output. I can also run javac from the C:Program_FilesJavajdk1.7.0in directory with no problem. However when I try to run it from somewhere else I got the error that it is not recognized. Where can be the problem. Am I missing anything?

推荐答案

打开命令行窗口，输入path"并检查C:Program FilesJavajdk1.7.0_02in"被列出.如果没有尝试在该窗口中设置路径(只是为了检查它是否有效):set path=C:Program FilesJavajdk1.7.0_02in"并再次尝试运行javac".

Open a command-line window, type "path" and check if "C:Program FilesJavajdk1.7.0_02in" is listed. If not try setting the path in that window (just to check if it works): "set path=C:Program FilesJavajdk1.7.0_02in" and try running "javac" again.
