当我从终端启动 nautilus 时，会打印以下错误并且 nautilus 没有打开。

可能是什么问题呢？？
当我从笔记本电脑上卸载 Gnome3 时遇到了一点问题（让它变慢了），并且软件包可能已经卸载了 nautilus 在该过程中需要的一些东西。现在，当我从 Unity 侧栏中单击 nautilus 时，它什么也不做。我在终端中输入 nautilus，这是它输出的内容：
tommydrum@crazypeople-ubuntu:~$ nautilus
Could not register the application: GDBus.Error:org.freedesktop.DBus.Error.UnknownMethod: No such interface `org.gtk.Actions' on object at path /org/gnome/Nautilus
当我从 unity 中右键单击 nautilus 并单击一个子文件夹时，它可以工作，但当我输入 nautilus 时就不行了/home/tommydrum/Downloads。当我以 root 身份运行 nautilus 时，会发生这种情况（它确实有效，但这是输出）：
tommydrum@crazypeople-ubuntu:~$ sudo -i nautilus
[sudo] password for tommydrum:
