Mac下搭建GO环境

1.download pkg: https://golang.org/dl/ 2.install pkg with password
3.config:
$ vim .bash_profile
export GOPATH=$HOME/work_go
export GOBIN=/usr/local/go/bin
export PATH="$PATH:$GOBIN"

$ source .bash_profile

$ go version
go version go1.6.2 darwin/amd64

$ go env
GOARCH="amd64"
GOBIN="/usr/local/go/bin"
GOEXE=""
GOHOSTARCH="amd64"
GOHOSTOS="darwin"
GOOS="darwin"
GOPATH="/Users/yanping/work_go"
GORACE=""
GOROOT="/usr/local/go"
GOTOOLDIR="/usr/local/go/pkg/tool/darwin_amd64"
GO15VENDOREXPERIMENT="1"
CC="clang"
GOGCCFLAGS="-fPIC -m64 -pthread -fno-caret-diagnostics -Qunused-arguments -fmessage-length=0 -fno-common"
CXX="clang++"
CGO_ENABLED="1"

GOPATH 日常开发的根目录;
GOBIN 是bin目录;

4.first program:
cd /Users/yanping/work_go/src/main

$ vim main.go
-----------------------------------------------------
package main
import (
"fmt"
       )
func main() {
fmt.Println("Hello , Yanping !");
}
-----------------------------------------------------
1.直接运行查看结果,不生成bin文件:
$ go run main.go
Hello , Yanping !
2.生成bin文件,然后执行bin文件:
$ go build main
$ ls
main main.go
$ ./main
Hello , Yanping !
