通过将 Windows 恢复到以前的状态来解决

消息（系统找不到指定的路径。）显示...

1) 当我打开新的 CMD (Win+R => cmd)。它从介绍开始。（在第 3 行）

Microsoft Windows [Version 6.1.7601]
Copyright (c) 2009 Microsoft Corporation.  All rights reserved.
The system cannot find the path specified.

C:\Users\ViliamKopecky>

2）当我执行一些命令时cmd /C dir（或cmd /C php -v或其他）（在第 2 行）

C:\Users\ViliamKopecky>cmd /C dir
The system cannot find the path specified.
 Volume in drive C is Windows7_OS
 Volume Serial Number is 8230-1246
...

C:\Windows\System32>cmd /C php -v
The system cannot find the path specified.
PHP 5.4.8 (cli) (built: Oct 16 2012 22:30:23)
Copyright (c) 1997-2012 The PHP Group
Zend Engine v2.4.0, Copyright (c) 1998-2012 Zend Technologies

3）（最烦人的）当我exec从 PHP 或 Node.js 或任何脚本语言运行函数时。（可能是从内部运行的cmd /C <command>）

消息不显示...

1）当我直接从cmd（或mingw，...）执行命令时

C:\Users\ViliamKopecky>dir
 Volume in drive C is Windows7_OS
 Volume Serial Number is 8230-1246

 Directory of C:\Users\ViliamKopecky

让我们从 cmd 的简单命令开始。

php -r "exec('dir', $stdout, $stderr); print(implode(\"\n\", $stdout), $stderr);"

结果是这样的（目录 test 是空的 - 这是正确的）：

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)

这表明该命令dir已从 php 正确执行。唯一错误的是第二行 -系统找不到指定的路径。- 那不应该在那里。

此消息由 exec 从PHP输出（也从Node.js as输出require('child_process').exec("dir", function(err, stdout, stderr) {console.log(stderr)});）

当我直接从 cmd（或 mingw 等）执行命令时，它会在没有消息的情况下正确执行。环境变量 PATH 似乎没问题。问题只是通过exec函数从脚本环境执行。

如何摆脱那个烦人的消息？谢谢

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.

This actually looks like a startup error with PHP, not with your code. Does

php -r "echo 1;"

also throw the same error? If so, your php.ini file or an include may be pathed incorrectly.

php -i

should give you more info.

此消息可能意味着PATH环境变量中的路径不存在。

以下 PowerShell 命令将打印缺少的路径。

($env:path).Trim(";").Split(";") | ? {-not (test-path $_)}

例如

> ($env:path).Trim(";").Split(";") | ? {-not (test-path $_)}
C:\Program Files\CMake\bin
C:\Program Files\SDCC\bin
C:\Users\wjbr\AppData\Local\Programs\Microsoft VS Code\bin

参考

我想你应该试试这个！我遇到了同样的问题并像这样解决了它：

ok type : cd\windows\system32 之后你会看到这个： System32/: Type what you want (ex:ipconfig): System32: ipconfig 然后就可以了！:)
