Compiler errors 新脚本：错误"；Finder出现错误：Can’；无法获取文件夹

教科书中的一个练习让我感到困惑，示例脚本：

tell application "Finder"

    tell folder "AppleScript" of folder "Applications"
        set file_list to name of every item
        set time_folder_was_created to creation date
        set time_folder_was_modified to modification date

    end tell
end tell

脚本编辑器一直给我这样的结果：错误“Finder获得错误：无法从文件夹“Applications”中获取文件夹“Applications\”编号-1728

这是否与过时的进程或OS 10.11 security for Applications文件夹有关，或者我没有看到它。

是

启动盘的子文件夹

tell application "Finder"
    tell folder "AppleScript" of folder "Applications" of startup disk
        set file_list to name of every item
        set time_folder_was_created to creation date
        set time_folder_was_modified to modification date
    end tell
end tell

或具有相对路径

set applicationsFolder to path to applications folder as text 
tell application "Finder"
    tell folder "AppleScript" of folder applicationsFolder
        set file_list to name of every item
        set time_folder_was_created to creation date
