获取脚本位置的父文件夹的路径：Applescript

背景：我正在尝试编写一个简单的applescript应用程序，它将启动一个tcl应用程序，但是我陷入了脚本的第一部分。

我需要获取applescript路径的父文件夹。当我运行此代码时：

set LauncherPath to path to me
set ParentPath to container of LauncherPath

...我得到这个错误：

error "Can’t get container of alias \"Macintosh HD:Users:simon:Downloads:folder with spaces:CrossFire-master:CrossFire Launcher for Mac.app:\"." number -1728 from container of alias "Macintosh HD:Users:simon:Downloads:folder with spaces:CrossFire-master:CrossFire Launcher for Mac.app:"

阅读此答案后，我尝试了以下方法：

set LauncherPath to path to me
set RealLauncherPath to first item of LauncherPath
set ParentPath to container of RealLauncherPath

...但是我得到了这个错误：

error "Can’t get item 1 of alias \"Macintosh HD:Users:simon:Downloads:folder with spaces:CrossFire-master:CrossFire Launcher for Mac.app:\"." number -1728 from item 1 of alias "Macintosh HD:Users:simon:Downloads:folder with spaces:CrossFire-master:CrossFire Launcher for Mac.app:"

任何帮助或想法，不胜感激。提前致谢！

PS一旦我解决了以上问题，完整的脚本将如下所示：

set LauncherPath to path to me
set RealLauncherPath to first item of LauncherPath
set ParentPath to container of RealLauncherPath
set UnixPath to POSIX path of ParentPath
set launcherCrossFire to "/usr/local/bin/wish " & UnixPath & "/CrossFire.tcl > /dev/null &" -- creat command to launch CrossFire
do shell script launcherCrossFire

更新：这是包含以下答案的工作脚本：

set UnixPath to POSIX path of ((path to me as text) & "::") --get path to parent folder
set LaunchCrossFire to "/usr/local/bin/wish '" & UnixPath & "CrossFire.tcl' > /dev/null 2>&1 &" -- creat command to launch CrossFire
do shell script LaunchCrossFire -- run command
