SETX不会将路径追加到系统路径变量 [英] SETX doesn't append path to system path variable

问题描述

我试过下面的命令通过批处理文件附加一些路径到系统路径变量：

  setx PATH％PATH ％; C：\Program Files\MySQL\MySQL Server 5.5 \bin
  

在运行上面的批处理文件之后检查系统变量路径，上面的路径不在那里。

可以看到所有窗口变量值内容如下：

  C：\程序文件（x86）\AMD APP\bin\x86_64; C： \Program Files（x86）\AMDAPP\bin\x86;％SystemRoot％\system32;％SystemRoot％;％SystemRoot％\System32\Wbem;％SYSTEMROOT％\System32\WindowsPowerShell\v1 .0 \; C：\ProgramFiles（x86）\ATI Technologies \ATI.ACE\Core-Static; 
  

我做错了什么？

如果你想改变系统级别的代码，广泛的环境变量，您必须使用 / M ：

  setx PATH％PATH ％; C：\Program Files\MySQL\MySQL Server 5.5\bin/ M 
  

setx.exe是关于/ M，BTW的放置。它需要在结束。

I have tried below command to append some path to system path variable by batch-file :

setx PATH "%PATH%;C:\Program Files\MySQL\MySQL Server 5.5\bin"

I have checked system variable path after running above batch-file, above path isn't in there.

You can see all windows Variable value content in below :

C:\Program Files (x86)\AMD APP\bin\x86_64;C:\Program Files (x86)\AMDAPP\bin\x86;%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;%SYSTEMROOT%\System32\WindowsPowerShell\v1.0\;C:\ProgramFiles (x86)\ATI Technologies\ATI.ACE\Core-Static;

What am i doing wrong?

解决方案

To piggy-back on @Endoro's answer (I lack the rep to comment):

If you want to change the system-wide environment variables, you have to use /M, a la:

setx PATH "%PATH%;C:\Program Files\MySQL\MySQL Server 5.5\bin" /M

setx.exe is picky about placement of the /M, BTW. It needs to be at the end.
