Macbook无法清空trash

有一个文件夹我无法从垃圾箱里清空，可能是之前一个旧的用户文件？我尝试清空垃圾箱时提示我voicetrigger在使用，library在使用。如果我选择立即删除，会报错：“The operation can’t be completed because some items had to be skipped. For each item, choose File > Get Info, make sure “Locked” is deselected, and then check the Sharing & Permissions section. When you are sure the items are unlocked and not designated as Read Only or No Access, try again.”

但是我按照提示操作，并不能解决。

请问各位有什么解决办法吗？
