我尝试将当前桌面图片设置为脚本当前目录中的图片。例如，如果我的文件夹结构是：
~/Documents/Scripts/DesktopImageScript/image.jpg
将脚本放在同一目录中，我希望能够将桌面图像设置为image.jpg，而无需直接引用文件夹结构。我目前用于获取当前目录的代码是：
tell application "System Events" to set app_directory to POSIX path of (container of (path to me))
问题不在于该代码，因为我可以使用预期的正确结果运行以下命令：
do shell script "echo " & app_directory
我认为问题出在我用来设置桌面图片的代码中：
tell application "Finder"
set desktop picture to POSIX file (quoted form of POSIX path of (app_directory & "/image.jpg"))
end tell
我尝试运行脚本时收到的错误是：
error "Finder got an error: AppleEvent handler failed." number -10000
不确定导致错误的原因或解决方法。任何帮助表示赞赏。完整的脚本如下：
tell application "System Events" to set app_directory to POSIX path of (container of (path to me))
tell application "Finder"
set desktop picture to POSIX file (quoted form of POSIX path of (app_directory & "/image.jpg"))
end tell

使用StackOverflow上另一个答案的代码解决。
tell application "System Events"
set theDesktops to a reference to every desktop
repeat with x from 1 to (count theDesktops)
set picture of item x of the theDesktops to app_directory & "/image.jpg"
end repeat
end tell
