如何让 NSIS RMDir 对子目录进行操作？
在 NSIS 安装程序脚本中，我有：
RMDir "$INSTDIR"
现在，如果用户将安装目录设置为 C:\Program Files\Product，它可以正常工作，但是如果他们安装到更深的目录，例如 例如，C:\Program Files\Company\Product，RMDir 会删除“Product”，但不会删除“Company”。我怎样才能让它删除每个空目录到根目录（不使用/r）...例如，如果为空则删除产品，如果为空则删除公司，如果为空则删除程序文件，等等？
编辑：我最终使用的功能：
# Delete empty directories recursively
var deleteDir
var dirLength
Function un.PathDeleteEmptyDirRecurse
ClearErrors
loop:
Sleep 50 ; Without a small delay here, the directory sometimes won't get removed
RMDir "$deleteDir" ; Remove the directory
IfErrors end
strlen $dirLength $deleteDir ; Store the length of the path
intcmp $dirLength 3 end end ; If the length of the path is <= 3 (e.g. C:\), we're at the root drive
GetFullPathName $deleteDir "$deleteDir\.." ; <path>\.. results in the parent directory of <path>
IfErrors end loop
end:
FunctionEnd
In an NSIS installer script I have:
RMDir "$INSTDIR"
Now, if the user sets the installation directory to C:\Program Files\Product, it works fine, however if they install to something deeper, such as C:\Program Files\Company\Product for example, RMDir gets rid of "Product" but not "Company". How can I make it delete each empty directory down to the root (WITHOUT using /r)... e.g. delete Product if empty, delete Company if empty, delete Program Files if empty, and so on?
EDIT: The function I ended up using:
# Delete empty directories recursively
var deleteDir
var dirLength
Function un.PathDeleteEmptyDirRecurse
ClearErrors
loop:
Sleep 50 ; Without a small delay here, the directory sometimes won't get removed
RMDir "$deleteDir" ; Remove the directory
IfErrors end
strlen $dirLength $deleteDir ; Store the length of the path
intcmp $dirLength 3 end end ; If the length of the path is <= 3 (e.g. C:\), we're at the root drive
GetFullPathName $deleteDir "$deleteDir\.." ; <path>\.. results in the parent directory of <path>
IfErrors end loop
end:
FunctionEnd

我假设您希望在卸载程序中而不是在安装程序中使用此命令：
I assume you want this in the uninstaller and not the installer:
这是我用的；
这让你可以在卸载中调用它
${RMDirUP} "$INSTDIR"Here's what I use;
This let's you call it in the uninstall with
${RMDirUP} "$INSTDIR"我最终仅使用这两行来删除安装目录和目录本身（如果为空）中的所有内容：
I finally ended up using just these two lines to delete everything in the installation directory and the directory itself (if empty):
