我正在尝试从这些说明中安装一些软件包：
http://www.franz.com/agraph/support/documentation/v4/server-installation.html#header3-25
我运行这个命令：
tar zxf agraph-4.2-linuxamd64.64.tar.gz 并得到这个错误：
tar: agraph-4.2-linuxamd64.tar.gz: Cannot open: No such file or directory tar: Error is not recoverable: exiting now tar: Child returned status 2 tar: Error exit delayed from previous errors
任何想法，为什么这可能发生，我怎么能使它工作？ 谢谢！
它看起来好像还没有下载该文件，或者您不在您下载该文件的目录中，或者您尝试打开的文件的名称与说明中指定的名称不同。 做一个'ls'，你看到那里的文件？
我能够下载该文件并成功解压：
