在Windows 7中使用NSIS设置环境variables

我想使用NSIS安装程序设置环境variables。 如果重要,我将在Windows 7上运行脚本。 谢谢!

我如何创建或更改环境变量

注意:以这种方式更改%path%是不安全的,如果它长于NSIS字符串长度,可能会损坏条目!

您可以创建一个Windows批处理文件,像安装其他文件一样将其打包,安装后将其解压到plugins目录并执行:

 File "/oname=$PluginsDir\appendvar.bat" "PathToScriptDir\appendvar.bat" nsExec::ExecToLog '"$SYSDIR\cmd.exe" /C "$PluginsDir\appendvar.bat" -g -all' Pop $R0 ; last error Delete "$PluginsDir\appendvar.bat" 

appendvar.bat脚本(某种全局和本地追加的通用实现):

 @echo off rem Drop last error level cd . rem Create local variable's stack setlocal set "?~nx0=%~nx0" rem script flags rem set variable in global registry for a current user set __FLAG_SET_GLOBAL_REGISTRY=0 rem Set variable in global registry for all users. rem Has no meaning if global flag has not used. set __FLAG_SET_GLOBAL_REGISTRY_ALL_USERS=0 rem If setting global variable, then do include changes for a local cmd.exe process environment (by default, it is excluded) rem Has no meaning if global flag has not used. set __FLAG_SET_LOCAL=0 rem Force append even if exist. set __FLAG_FORCE=0 :FLAGS_LOOP rem flags always at first set "__FLAG=%~1" if not "%__FLAG%" == "" ^ if not "%__FLAG:~0,1%" == "-" set "__FLAG=" if not "%__FLAG%" == "" ( if "%__FLAG%" == "-g" ( set __FLAG_SET_GLOBAL_REGISTRY=1 shift ) else if "%__FLAG%" == "-all" ( if %__FLAG_SET_GLOBAL_REGISTRY% NEQ 0 set __FLAG_SET_GLOBAL_REGISTRY_ALL_USERS=1 shift ) else if "%__FLAG%" == "-l" ( set __FLAG_SET_LOCAL=1 shift ) else if "%__FLAG%" == "-f" ( set __FLAG_FORCE=1 shift ) else ( echo.%?~nx0%: error: invalid flag: %__FLAG% exit /b -255 ) >&2 rem read until no flags goto FLAGS_LOOP ) if "%~1" == "" ( echo.%?~nx0%: error: variable name is not set. exit /b 1 ) set "__SEPARATOR=" if not "%~3" == "" set "__SEPARATOR=%~3" if "%__SEPARATOR%" == "" set "__SEPARATOR=;" set "__SEPARATOR=%__SEPARATOR:~0,1%" set "__NEW_VALUE=%~2" rem remove trailing separator character if not "%__NEW_VALUE%" == "" ( if "%__SEPARATOR%" == "%__NEW_VALUE:~-1%" ( set "__NEW_VALUE=%__NEW_VALUE:~0,-1%" ) ) rem remove trailing "\" character if not "%__NEW_VALUE%" == "" ( if "\" == "%__NEW_VALUE:~-1%" ( set "__NEW_VALUE=%__NEW_VALUE:~0,-1%" ) ) if "%__NEW_VALUE%" == "" ( if "%~2" == "" exit /b 0 rem the variable value is a separator character only exit /b 2 ) rem set local at least if %__FLAG_SET_GLOBAL_REGISTRY%%__FLAG_SET_LOCAL% EQU 0 set __FLAG_SET_LOCAL=1 if %__FLAG_SET_GLOBAL_REGISTRY% EQU 0 goto SET_GLOBAL_END rem global setup set "__VAR_VALUE=" if %__FLAG_SET_GLOBAL_REGISTRY_ALL_USERS% NEQ 0 ( set __FLAG_SET_GLOBAL_REGISTRY_WMIC_WHERE_EXP=where "Name='Path' and UserName='<SYSTEM>'" ) else ( set __FLAG_SET_GLOBAL_REGISTRY_WMIC_WHERE_EXP=where "Name='Path' and UserName!='<SYSTEM>'" ) for /F "usebackq eol= tokens=1,* delims==" %%i in (`wmic environment %__FLAG_SET_GLOBAL_REGISTRY_WMIC_WHERE_EXP% get VariableValue /VALUE 2^>NUL`) do if "%%i" == "VariableValue" set "__VAR_VALUE=%%j" if not "%__VAR_VALUE%" == "" ( if "%__SEPARATOR%" == "%__VAR_VALUE:~-1%" ( set "__VAR_VALUE=%__VAR_VALUE:~0,-1%" ) ) rem check on existance if %__FLAG_FORCE% NEQ 0 goto SET_GLOBAL_IMPL if "%__VAR_VALUE%" == "" goto SET_GLOBAL_IMPL set "__VAR_VALUE_TMP=%__SEPARATOR%%__VAR_VALUE%%__SEPARATOR%" call set "__VAR_VALUE_TMP_EXCLUDED=%%__VAR_VALUE_TMP:%__SEPARATOR%%__NEW_VALUE%%__SEPARATOR%=%%" if /i not "%__VAR_VALUE_TMP_EXCLUDED%" == "%__VAR_VALUE_TMP%" goto SET_GLOBAL_END :SET_GLOBAL_IMPL if not "%__VAR_VALUE%" == "" ( wmic environment %__FLAG_SET_GLOBAL_REGISTRY_WMIC_WHERE_EXP% set VariableValue="%__VAR_VALUE%%__SEPARATOR%%__NEW_VALUE%" ) else ( wmic environment %__FLAG_SET_GLOBAL_REGISTRY_WMIC_WHERE_EXP% set VariableValue="%__NEW_VALUE%" ) :SET_GLOBAL_END if %__FLAG_SET_LOCAL% EQU 0 exit /b rem local setup call set "__VAR_VALUE=%%%~1%%" if not "%__VAR_VALUE%" == "" ( if "%__SEPARATOR%" == "%__VAR_VALUE:~-1%" ( set "__VAR_VALUE=%__VAR_VALUE:~0,-1%" ) ) rem check on existance if %__FLAG_FORCE% NEQ 0 goto SET_LOCAL_IMPL if "%__VAR_VALUE%" == "" goto SET_LOCAL_IMPL set "__VAR_VALUE_TMP=%__SEPARATOR%%__VAR_VALUE%%__SEPARATOR%" call set "__VAR_VALUE_TMP_EXCLUDED=%%__VAR_VALUE_TMP:%__SEPARATOR%%__NEW_VALUE%%__SEPARATOR%=%%" if /i not "%__VAR_VALUE_TMP_EXCLUDED%" == "%__VAR_VALUE_TMP%" goto SET_LOCAL_END :SET_LOCAL_IMPL if not "%__VAR_VALUE%" == "" ( endlocal set "%~1=%__VAR_VALUE%%__SEPARATOR%%__NEW_VALUE%" ) else ( endlocal set "%~1=%__NEW_VALUE%" ) :SET_LOCAL_END exit /b 0 

你可以替换

 %__VAR_VALUE%%__SEPARATOR%%__NEW_VALUE% 

 %__NEW_VALUE%%__SEPARATOR%%__VAR_VALUE% 

如果想要预先设置一个变量值。

注意:脚本有问题:

  • 值与忽略大小写比较
  • 可以更新超过1024个字符(测试),但不超过4096个字符我认为(未测试)
  • 如果使用-g和-all标志,则cmd.exe进程必须以管理员权限运行。

更新RegAddPathToVar函数的最新版本在这里: https : RegAddPathToVar (完整的测试例子: https : RegAddPathToVar test_RegAddRemovePathGUI / main.nsi )

这是NSIS 3.0的完整且直接的实现示例。

包含3个文件。

build.bat – 建立脚本文件。

 @echo off set "MAKENSIS_EXE=makensis.exe" "%MAKENSIS_EXE%" /V4 "/Obuild.log" "/XOutFile '%~dp0test.exe'" "%~dp0main.nsi" echo.Return code: %ERRORLEVEL% pause 

编辑MAKENSIS_EXE变量到那里makensis可执行文件在您的系统上。

stack.nsi – 帮助函数文件。
