go语言环境配置
1.使用brew安装最新稳定版本的go 1.13
brew search go

==> Pouring go@1.13-1.13.10_1.catalina.bottle.tar.gz
==> Caveats
go@1.13 is keg-only, which means it was not symlinked into /usr/local,
because this is an alternate version of another formula.
If you need to have go@1.13 first in your PATH run:
echo 'export PATH="/usr/local/opt/go@1.13/bin:$PATH"' >> ~/.zshrc

到这一步go即安装完成了
2.配置go
go env
GO111MODULE=""
GOARCH="amd64"
GOBIN="/Users/zhaojianqiang/Documents/code/go/bin"
GOCACHE="/Users/zhaojianqiang/Library/Caches/go-build"
GOENV="/Users/zhaojianqiang/Library/Application Support/go/env"
GOEXE=""
GOFLAGS=""
GOHOSTARCH="amd64"
GOHOSTOS="darwin"
GONOPROXY=""
GONOSUMDB=""
GOOS="darwin"
GOPATH="/Users/zhaojianqiang/Documents/code/go"
GOPRIVATE=""
GOPROXY="https://proxy.golang.org,direct"
GOROOT="/usr/local/opt/go@1.13/libexec"
GOSUMDB="sum.golang.org"
GOTMPDIR=""
GOTOOLDIR="/usr/local/opt/go@1.13/libexec/pkg/tool/darwin_amd64"
GCCGO="gccgo"
AR="ar"
CC="clang"
CXX="clang++"
CGO_ENABLED="1"
GOMOD=""
CGO_CFLAGS="-g -O2"
CGO_CPPFLAGS=""
CGO_CXXFLAGS="-g -O2"
CGO_FFLAGS="-g -O2"
CGO_LDFLAGS="-g -O2"
PKG_CONFIG="pkg-config"
GOGCCFLAGS="-fPIC -m64 -pthread -fno-caret-diagnostics -Qunused-arguments -fmessage-length=0 -fdebug-prefix-map=/var/folders/1v/hmp36dtx5wlbpc2zpkk2w2h80000gp/T/go-build469326368=/tmp/go-build -gno-record-gcc-switches -fno-common"
将GOROOT, GOPATH配置到.bash_profile中
vim .bash_profile
#添加如下 注意GOPATH不要配置到go的安装目录下,可以自定义一个目录
#GOROOT： go安装目录
#GOPATH：go工作目录
#GOBIN：go可执行文件目录
#PATH：将go可执行文件加入PATH中，使GO命令与我们编写的GO应用可以全局调用
export GOROOT=/usr/local/opt/go\@1.13
export GOPATH=/Users/zhaojianqiang/Documents/code/go
export GOBIN=$GOPATH/bin
export PATH=$PATH:$GOBIN:$GOROOT/bin
#完成后保存并使之生效
source .bash_profile
再次使用go env查看, 即可看到刚才配置的信息
到此go就完全安装完成了, 常用工具用GoLand, 开始你的go编程之路吧
3.linux配置 以上是mac os系统配置go, linux的go环境配置相当简单
# step1 下载包
wget https://dl.google.com/go/go1.14.4.linux-amd64.tar.gz
# step2 解压
tar -C /usr/local -xzf go1.14.4.linux-amd64.tar.gz
# step3 环境变量配置 在/etc/profile文件追加
export PATH=$PATH:/usr/local/go/bin
# step4 测试安装 创建一个hello.go文件,包含以下代码
package main
import "fmt"
func main() {
fmt.Printf("hello, world\n")
}
# 编译
go build hello.go
# 运行,成功后输入hello, world
./hello
