golang.org/x/sys/unix: unrecognized

安装的过程中报错 ：

package golang.org/x/sys/unix: unrecognized import path "golang.org/x/sys/unix" (https fetch: Get https://golang.org/x/sys/unix?go-get=1: dial tcp 216.239.37.1:443: i/o timeout)

被长城墙了，您可以这这么操作：(参看 http://www.fecshop.com/topic/805)

 cd ~/go/src
 mkdir -p golang.org/x
 cd golang.org/x
 git clone https://github.com/golang/sys.git
