Java不被识别为内部或外部命令 [英] Java is not recognized as an internal or external command

问题描述

所以我有一个麻烦的问题.

So guys I have a huuuuuge problem.

我下载了Java jdk 1.8.0_45.

I downloaded java jdk 1.8.0_45.

它工作正常，但是因为我要制造Runescape Private Server，所以必须将我的类路径和路径放入环境变量中.我做到了，当我尝试打开Java时，它说:

It was working fine , but because I was making a Runescape Private Server I had to put in my classpath and path in my environmental variables. I did that and when I tried to open java then it said :

java不被识别为内部或外部命令

java is not recognized as an internal or external command

所以我发现类路径和路径是错误的.但是他们不是，我这样把它们放进去.

so I figured the classpath and path were wrong. But they weren't , I put them in like this.

C:\ Program Files \ Java \ jdk1.8.0_45 \ bin

C:\Program Files\Java\jdk1.8.0_45\bin

我检查了文件夹，这就是正确的类路径.我尝试删除类路径和路径后将其恢复到正常状态，但这没有用，它一直说无法识别java.我重新启动了PC，甚至没有进行系统还原，但没有任何效果.

I checked the folders and that is exactly the correct classpath. I tried deleting the classpath and path after to restore it back to normal but that didn't work , it kept saying that java is not recognized. I restarted my pc and even did a system restore but nothing worked.

需要帮助.

推荐答案

将JAVA_HOME = path \ to \ java-dir设置为jdk

set JAVA_HOME=path\to\java-dir upto jdk

set PATH =％PATH％;％JAVA_HOME％\ bin

set PATH=%PATH%;%JAVA_HOME%\bin

请参见 https://docs.oracle.com/javase/tutorial/essential/environment/paths.html
