UWP Helper批处理脚本报错：字符串缺少终止符'，请求修复

问题原因 #

错误根源是批处理调用PowerShell时使用了单引号'。在批处理环境中，单引号不具备字符串边界的作用，当脚本所在路径包含空格或特殊字符时，批处理会拆分带单引号的参数，导致PowerShell收到不完整的字符串，触发The string is missing the terminator: '错误。

修复后的完整脚本 #

@echo off

echo UWP Helper & echo.

:begin
echo 1. Install game
echo 2. Install DLC
echo 3. Enable Developer Mode
echo 4. Disable Developer Mode
echo 5. Exit

set /p action="Choose action: "

IF NOT "%action%" == "1" ( IF NOT "%action%" == "2" ( IF NOT "%action%" == "3" ( IF NOT "%action%" == "4" ( IF NOT "%action%" == "5" (  goto begin ) ) ) ) )

IF "%action%" == "1" ( goto gameinstall )
IF "%action%" == "2" ( goto dlcinstall )
IF "%action%" == "3" ( goto developeron )
IF "%action%" == "4" ( goto developeroff )
IF "%action%" == "5" ( goto exit )

powershell -Command "Add-AppxPackage ""%~dp0AppxManifest.xml"" -Register"
goto begin

:dlcinstall
set dlc_directory="%~dp0MicrosoftStore_DLC\\"
set dlc_pattern=AppxManifest.xml
set sign_pattern=*.p7x
set file_check_new="AppxSignature.tmp"

IF EXIST %dlc_directory% ( cd %dlc_directory% )

IF EXIST %dlc_directory% ( FOR /R %%I in (%sign_pattern%) DO IF EXIST "%%I" ( REN "%%I" %file_check_new% ) ) ELSE ( echo DLC directory does not exist. )

IF EXIST %dlc_directory% ( FOR /R %%I in (%dlc_pattern%) DO IF EXIST "%%I" ( powershell -Command "Add-AppxPackage ""%%I"" -Register" ) ) ELSE ( echo DLC directory does not exist. )

IF EXIST %dlc_directory% ( cd .. )
goto begin

:exit

关键修复点 #

• 将调用PowerShell的语句从powershell Add-AppxPackage '路径' -Register改为powershell -Command "Add-AppxPackage ""路径"" -Register"
• 用双引号包裹PowerShell命令，内部路径的双引号用""转义，确保批处理正确传递完整路径给PowerShell，避免参数拆分问题
