freebsd - 无法在 FreeBSD 10.1 上安装 crossbar.io 二进制包

Question

我无法在 FreeBSD 10.1 上安装 crossbar.io WAMP 路由器的二进制发行版

我正在按照手册（ http://crossbar.io/docs/Installation-on-FreeBSD/ ）一步一步地做，但是在pkg install crossbar我得到这个输出期间：

The following 1 package(s) will be affected (of 0 checked):

The process will require 161 MiB more space.

Proceed with this action? [y/N]: y

并且什么都没有安装，只有空文件夹/opt/crossbar

难道我做错了什么？

任何输入将不胜感激。
