练习中TAR出错

[root@localhost ~]# tar -zcf test test.tar.gz
tar: test: Cannot opentar: test.tar.gz: Cannot stat: No such file or directory
: Is a directory
tar: Error is not recoverable: exiting now
tar: Child returned status 2
tar: Error exit delayed from previous errors
提示没有找到目录，但是目录确实是存在的啊！请问一般出现这样问题如何解决？

tar -zcf test.tar.gz test

压缩后的文件名写前面，要压缩的目录写后面
