选择linux版下载
把包下载下来，解压到/usr/local/下
tar -C /usr/local -zxvf go1.10.3…….
然后在桌面上创建一个目录
sparrow@captain:~/桌面$ mkdir Golang
sparrow@captain:~/桌面/Golang$ mkdir src pkg bin
sparrow@captain:~/桌面/Golang$ ls
bin pkg src
sparrow@captain:~/桌面/Golang$ sudo vim ~/.bashrc
在文件最后添加
export PATH=$PATH:/usr/local/go/bin
export GOPATH=/home/sparrow/桌面/Golang
路径请根据实际情况修改。
sparrow@captain:~/桌面/Golang$ source ~/.bashrc
sparrow@captain:~/桌面/Golang$ go ##测试是否生效
出现以下结果

sparrow@captain:~/桌面/Golang$ go version //查看go版本
sparrow@captain:~/桌面/Golang$ cd src/
sparrow@captain:~/桌面/Golang/src$ ls
sparrow@captain:~/桌面/Golang/src$ mkdir hello
sparrow@captain:~/桌面/Golang/src$ cd hello/
sparrow@captain:~/桌面/Golang/src/hello$ touch hello.go
sparrow@captain:~/桌面/Golang/src/hello$ vim hello.go
内容如下，向世界问好。
package main
import “fmt”
func main() {
fmt.Println(“hello world！”)
}
sparrow@captain:~/桌面/Golang/src/hello$ go install hello //编译hello.go
sparrow@captain:~/桌面/Golang/src$ cd ../bin
sparrow@captain:~/桌面/Golang/bin$ ./hello
hello world!
或者直接使用go run 命令执行代码。
sparrow@captain:~/桌面/Golang/src/hello$ go run hello
hello world!
