最近在学习codis，安装过程中，在执行bootstrap.sh时报错，本人没学过go,哪位大神能帮忙看一下吗，谢谢
./bootstrap.sh
downloading dependcies, it may take a few minutes...
go build -o bin/codis-proxy ./cmd/proxy
# _/usr/local/codis/cmd/proxy
cmd/proxy/main.go:192: undefined: utils.Version
cmd/proxy/main.go:193: undefined: utils.Compile
make: *** [build-proxy] 错误 2
