今天想安装个iris框架，执行命令行：go get -u -v github.com/kataras/iris
后就卡住了， 过了好久命令行提示如下：
PS C:\Users\dewff> go get -u github.com\kataras\iris
# cd .; git clone https://github.com/kataras/iris D:\go_workspace\src\github.com\kataras\iris
Cloning into 'D:\go_workspace\src\github.com\kataras\iris'...
fatal: early EOF
fatal: The remote end hung up unexpectedly
fatal: index-pack failed
error: RPC failed; curl 18 transfer closed with outstanding read data remaining
package github.com/kataras/iris: exit status 128
我的git环境变量也配了，再任意目录下都可执行git --version
求大神告知啥原因？？？？
