MacOS Go开发环境配置

MacOS Go开发环境配置

Homebrew

安装Homebrew

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

脚本很可能会停在

==> Tapping homebrew/core
 
Cloning into '/usr/local/Homebrew/Library/Taps/homebrew/homebrew-core'...

具体的解决方法可以参考：

之后下载go make等工具时，会出现下载龟速的情况，因为homebrew默认的是国外的源，下载的很慢，所以需要更换源为国内的

# 替换brew.git:
$ cd "$(brew --repo)"
# 中国科大:
$ git remote set-url origin https://mirrors.ustc.edu.cn/brew.git
# 清华大学:
$ git remote set-url origin https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/brew.git
 
# 替换homebrew-core.git:
$ cd "$(brew --repo)/Library/Taps/homebrew/homebrew-core"
# 中国科大:
$ git remote set-url origin https://mirrors.ustc.edu.cn/homebrew-core.git
# 清华大学:
$ git remote set-url origin https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/homebrew-core.git
 
# 替换homebrew-bottles:
# 中国科大:
$ echo 'export HOMEBREW_BOTTLE_DOMAIN=https://mirrors.ustc.edu.cn/homebrew-bottles' >> ~/.bash_profile
$ source ~/.bash_profile
# 清华大学:
$ echo 'export HOMEBREW_BOTTLE_DOMAIN=https://mirrors.tuna.tsinghua.edu.cn/homebrew-bottles' >> ~/.bash_profile
$ source ~/.bash_profile
 
# 应用生效:
$ brew update

Go安装

可以直接通过brew命令工具安装，或者在golang官网下载安装。

brew install go

Go官网 golang.org

Go语言中文网 studygolang

.bash_profile

##brew更换

export HOMEBREW_BOTTLE_DOMAIN=https://mirrors.ustc.edu.cn/homebrew-bottles

###golang env

#golang proxy

export GOPROXY=https://mirrors.aliyun.com/goproxy/

#GOPATH

export GOPATH=$HOME/golang-project

#protoc-gen-go, protoc-gen-grpc-gateway, protoc-gen-swagger

export PATH=$PATH:/usr/local/opt/go/libexec/bin:$GOPATH/bin`

#go mod

export GO111MODULE=on

protobuf相关安装

主要有

1. protoc
2. protoc-gen-go
3. protoc-gen-grpc-gateway
4. protoc-gen-swagger

安装方法如下：

brew install protoc
go install github.com/grpc-ecosystem/grpc-gateway/protoc-gen-grpc-gateway
go install github.com/grpc-ecosystem/grpc-gateway/protoc-gen-swagger
go install github.com/golang/protobuf/protoc-gen-go

安装后protoc-gen-go, protoc-gen-grpc-gateway, protoc-gen-swagger的路径是$GOPATH/bin，需要将它们加入到PATH中，比如加入到.bash_profile中，添加下面这行

export PATH=$PATH:/usr/local/opt/go/libexec/bin:$GOPATH/bin

使用示例：

根据proto生成pb代码，网关api代码，swagger文档

protoc使用方法：protoc -h

生成stub, gw, swagge文档：https://github.com/grpc-ecosystem/grpc-gateway

#!/bin/bash
 
set -e
set -x
 
GEN_PATH=./
 
PROTOS=`find . -name  "*.proto" | awk -F './' '{print $2}'`
echo ${PROTOS}
for i in ${PROTOS}; do
    echo $i;
    #生成platform.pb.go
    protoc -I/usr/local/include --proto_path=$GOPATH/src:. --proto_path=$GOPATH/src/github.com/grpc-ecosystem/grpc-gateway/third_party/googleapis \
        --go_out=plugins=grpc,paths=source_relative,:${GEN_PATH} $i;
    #生成platform.pb.gw.go, platform.swagger.json
    protoc -I/usr/local/include --proto_path=$GOPATH/src:. --proto_path=$GOPATH/src/github.com/grpc-ecosystem/grpc-gateway/third_party/googleapis \
        --swagger_out=logtostderr=true:. --grpc-gateway_out=logtostderr=true:${GEN_PATH}   $i;
done

常见问题

gocode-gomod安装失败

如果在上述安装插件的过程中出现gocode-gomod问题，解决办法如下

按照之前设置go代理之后，开启go module

export GO111MODULE=on

# 下载gocode
go get -u github.com/stamblerre/gocode

# 下载完成后进入`GOPATH`中的`bin`文件中修改gocode
mv gocode gocode-gomod

# 再次下载gocode
go get -u github.com/mdempsky/gocode
