javac 在 Windows 7 中不被识别为内部或外部命令 [英] javac is not recognized as an internal or external command in windows 7

问题描述

我已经设置了 JAVA_HOME 和 PATH 变量.

I have set JAVA_HOME and PATH variable.

JAVA_HOME 看起来像这样:

JAVA_HOME looks like this:

C:\Program Files\Java\jdk1.8.0_60

PATH 看起来像这样:

PATH looks like this:

    %SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;%SYSTEMROOT%\System32\WindowsPowerShell\v1.0\;

    "C:\Program Files\nodejs\" "C:\Program Files (x86)\Brackets\command";C:\mongodb\bin;"C:\Program Files\cURL\bin" ;C:\Python34\python.exe; 

"%JAVA_HOME%/bin" ;

但它找不到任何 java 命令，如 javac 或 java，

Yet it can not find any of the java commands like javac or java,

用户路径变量:

 C:\Program Files\nodejs\node_modules\npm\; C:\Users\dev4\AppData\Roaming\npm; C:\mongodb\bin; " %JAVA_HOME%\bin\" ; "%ANT_HOME%\bin\" ;

系统路径变量:

%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;%SYSTEMROOT%\System32\WindowsPowerShell\v1.0\; C:\Program Files\nodejs\ ; C:\Program Files (x86)\Brackets\command;C:\mongodb\bin;C:\Program Files\cURL\bin ;C:\Python34\python.exe; %JAVA_HOME%\bin\;

尽管 npm 命令也不起作用.

Despite npm command is not working either.

这些以前一直在工作，但是自从我尝试为 java 设置路径以来，它们都已停止工作

These have been working before but since I was trying to set path for java , al of them have stopped working

推荐答案

请使用 \ 反斜杠 而不是 / 正斜杠 那是你路径设置的问题

Please use \ backslash not / forward slash That is the issue in your Path setup
