protoc

@protoc-gen-go的坑

问题背景

最近从java转go学习grpc过程中，由于要使用用protoc和protoc-gen-go，所以在安装相关grpc环境中出现了一些坑，这里给各位刚入门的
朋友分享下，避免踩坑

安装protoc-gen-go

1.go get -u github.com/golang/protobuf/protoc-gen-go

然后就出现了一堆错误

package google.golang.org/protobuf/compiler/protogen: unrecognized import path "google.golang.org/protobuf/compiler/protogen" (https fetch: Get =1: dial tcp 216.239.37.1:443: connectex: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.)

what fuck? 为什么down不下来？
难道protoc-gen-go更新了？
看了相关issue之后发现了问题，
然后果断get老版本：

go get -u github.com/golang/protobuf/protoc-gen-go@v1.4.0

成功搞定
