1）当我从cmd（或mingw，...）执行命令
C：\Users\ViliamKopecky> dir
驱动器C中的卷为Windows7_OS
卷序列号为8230-1246
目录的C：\Users\ViliamKopecky
php -rexec（'dir'，$ stdout，$ stderr）; print（implode \\\\\
\，$ stdout），$ stderr）;
，结果如下目录测试为空 - 这是正确的）：
E：\test> php -rexec （'dir'，$ stdout，$ stderr）; print（implode（\\\\
\，$ stdout），$ stderr）;
系统找不到指定的路径。
驱动器E中的卷是www
卷序列号是0C99-95EC
E目录：\test
09.11.2012 22:42 < DIR> 。
09.11.2012 22:42< DIR> ..
0文件0字节
2 Dir（s）13 495 296 000字节free
int（1）
这说明命令 dir 正确地从php执行。只有错误的事情是第二行 - 系统找不到指定的路径。 - 不应该在那里。
通过exec从 PHP （也从 Node.js 作为 require（'child_process'））exec（dir，function（err，stdout ，stderr）{console.log（stderr）}）; ）
当我从cmd（或mingw等）它会正确执行而不包含消息。环境变量PATH似乎确定。问题只是从脚本环境通过
exec 函数执行。 如何摆脱烦人的消息？感谢
问题是，当您运行cmd.exe时，某些程序已设置为autorun。
在我的例子中是ANSICON安装...然后我移动了该文件没有正确卸载。
我在这篇博文中找到了一个解决方案：
简短版本是找到
HKCU\软件\Microsoft\Command Processor\AutoRun
并清除该值。
Solved by restoring Windows to previous stateThe message (The system cannot find the path specified.) shows...

2) When i execute some command like cmd /C dir (or cmd /C php -v or whatever) (on line 2)

3) (the most annoying) when i run exec function from PHP or Node.js or probably any scripting lang. (which are probably runned from inside as cmd /C <command>)
1) when i execute the command right from the cmd (or mingw, ...)
C:\Users\ViliamKopecky>dir
Volume in drive C is Windows7_OS
Volume Serial Number is 8230-1246
Directory of C:\Users\ViliamKopecky
Let's start with simple command from cmd.
php -r "exec('dir', $stdout, $stderr); print(implode(\"\n\", $stdout), $stderr);"
and the result is like this (the directory test is empty - that is correct):
E:\test>php -r "exec('dir', $stdout, $stderr); print(implode(\"\n\", $stdout), $stderr);"
The system cannot find the path specified.
Volume in drive E is www
Volume Serial Number is 0C99-95EC
Directory of E:\test
09.11.2012 22:42 <DIR> .
09.11.2012 22:42 <DIR> ..
0 File(s) 0 bytes
2 Dir(s) 13 495 296 000 bytes free
int(1)
Which shows that the command dir has is executed from php correctly. Only thing thats wrong is the second line - The system cannot find the path specified. - that should not be there.
This message is output by exec from PHP (and also from Node.js as require('child_process').exec("dir", function(err, stdout, stderr) {console.log(stderr)});)
When I execute command right from cmd (or mingw, etc.) it executes correctly without the message. Environment variable PATH seem ok. Problem is just executing from script environment through exec functions.
How to get rid of that annoying message? Thanks
The problem is that some program has been set to autorun when you run cmd.exe.In my case it was ANSICON that was installed... and then I moved the file without properly uninstalling.
I found a solution in this blog post:
http://carol-nichols.com/2011/03/17/the-system-cannot-find-the-path-specified/
The short version is to find
HKCU\Software\Microsoft\Command Processor\AutoRun
and clear the value.
