 go get -u github.com/gin-gonic/gin

==Use a vendor tool like Govendor==
  go get github.com/kardianos/govendor #在墙外非常快

 sudo apt  install govendor # apt 

 mkdir -p $GOPATH/src/github.com/myusername/project && cd "$_"

===Vendor init your project and add gin ===
 <pre>
govendor init
govendor fetch github.com/gin-gonic/gin@v1.3

#有时要绝对路径  @后面也可以不加  有时一定要加
/root/go/bin/govendor fetch github.com/gin-gonic/gin@v1.6
</pre>
