Mac下环境搭建(用brew安装go和protoc)

brew install go

  vim ~/.zshrc, 追加以下内容
# brew
export PATH=/opt/homebrew/bin:$PATH

# Go
export http_proxy="http://127.0.0.1:12639"
export https_proxy="http://127.0.0.1:12639"
export no_proxy=localhost,127.0.0.1,.qq.com,.tencent.com

brew install grpc
brew install protobuf
brew install protoc-gen-go
brew install protoc-gen-go-grpc

➜  ~ go version
go version go1.17.2 darwin/amd64
➜  ~ protoc --version
libprotoc 3.17.3
➜  ~ protoc-gen-go --version
protoc-gen-go v1.27.1

protoc --go_out=. demo_service.proto
protoc --go-grpc_out=. demo_service.proto

option go_package ="./";
//如果加入该语句，会覆盖掉之前的package MedBaike;（该语句作用：在生成的pb.go文件指明所属包名），导致包名错误
//此时可以写为option go_package ="./;MedBaike";（分号前指明文件生成所在目录，分号后指明所属包名）

syntax = "proto3";

option go_package ="./;MedBaike";

package MedBaike;
