• 如果使用bash 编辑vim .bash_profile

╰─➤  echo $SHELL                                                                                                                                                                                                                          
/bin/zsh
╰─➤  mkdir ~/go

╰─➤  vim .zshrc
export GOPATH=$HOME/go
export GOROOT=/usr/local/Cellar/go/1.12.5/libexec
export PATH=$PATH:$GOPATH/bin
export PATG=$GOROOT/bin

╰─➤  source .zshrc
╰─➤  echo $GOPATH
/Users/y50/go
╰─➤  echo $GOROOT
/usr/local/Cellar/go/1.12.5/libexec
╰─➤  which go
/usr/local/bin/go

╰─➤  mkdir  ~/go/bin
╰─➤  mkdir  ~/go/pkg
╰─➤  mkdir  ~/go/src
╰─➤  ls ~/go/
bin pkg src

GOPATH
bin 可执行文件
pkg 包文件
src 源码

• 查看go环境

╰─➤  go env

• go测试

╰─➤  mkdir  ~/go/src/hello
╰─➤  cd ~/go/src/hello
╰─➤  touch main.go
╰─➤  cat main.go                                                                                                                                                                                                                        
package main
import "fmt"
func main(){
        fmt.Println("Hello, World!")
}

╰─➤  go build main.go
╰─➤  go run main.go
Hello, World!

3，go命令

go get
go run
go build
go fmt
go install
go test
go doc

4，Sublime Text3 go开发环境

• Package Control 安装
• 安装插件 GoSublime
  
  
  
• 手动安装 GoSublime

╰─➤  git clone https://margo.sh/GoSublime

• 查看包路径
  
• 把GoSublime拷贝到包路径，重启
