如何修复此cmd脚本字符串解析错误

Question

我的系统路径是：

我正在尝试使用脚本更新注册表项（系统路径）但是出现了一个奇怪的错误：

>myscript.cmd
\Python36-32\Scripts\ was unexpected at this time.

如何解决脚本错误？

这是脚本：

echo off

SET PROGPATH=C:\dell\mypath

for /f "tokens=2*" %%a in ('REG QUERY "HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Environment" /v Path') do set "SysPath=%%~b"

echo system path is: %SysPath%

echo %SysPath%>tmppath.txt

echo %PATH% | findstr /i %PROGPATH%
if %ERRORLEVEL% EQU 1 (
   echo %PROGPATH% path not found in system path

   REM we now add to syspath and then write back to registry
    set UPDATEDPATH=%PROGPATH%;%SysPath%

   REM we now just write UPDATEDPATH back to registry
   REG ADD "HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Environment" /f /v "Path" /t REG_SZ /d "%UPDATEDPATH%" 

    echo %PROGPATH% should now be added to the system path
) else (
   echo %PROGPATH% already in path
)

问题在于：echo％PATH％| grep％PROGPATH％

只要有

，就会收到错误

C:\Program Files (x86)\Java\jre1.8.0_45\bin;

或类似的东西。

即（x86）\ J或（x86）\ P等

那么如何解决这个问题？

被问到更多细节。所以在这里。

在运行脚本之前，我的环境是这样的：

键名：

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment

路径键具有值：

现在，如果我运行批处理文件内容，我将其命名为path3.cmd，我得到：

>path3.cmd
\Python36-32\Scripts\ was unexpected at this time.

尝试

echo %PATH% | findstr /i /c:"%PROGPATH%"

或

echo "%PATH%" | findstr /i /c:"%PROGPATH%"

没有区别。

这个错误似乎在这一行：

set UPDATEDPATH=%PROGPATH%;%SysPath%
