mac下搭建go编译环境及其开发工具goland并激活

1、下载mac需要安装的文件包，点击pkg，一直下一步安装即可完成。

https://golang.org/doc/install?download=go1.12.6.darwin-amd64.pkg

软件包将被安装到 /usr/local/go

检查安装包是否安装成功

neusoftdeMacBook-Pro:go neusoft$ go version

go version go1.12.6 darwin/amd64

2、配置环境变量
1、打开终端，进入用户主目录

cd ~

2、输入ls -all命令查看是否存在.bash_profile;

neusoftdeMacBook-Pro:~ neusoft$ ls -all

3、存在既使用vim .bash_profile打开文件;

vim .bash_profile

4、输入下面代码，

其中

• GOPATH: 日常开发的根目录。

• GOBIN:是GOPATH下的bin目录。

使用方法一安装，可配置

export GOPATH=/usr/local/go

export GOBIN=$GOPATH/bin

export PATH=$PATH:$GOBIN

5、执行source，让配置生效

source ~/.bash_profile 

6、检查环境变量是否配置成功

go env

neusoftdeMacBook-Pro:testdata neusoft$ go env
warning: GOPATH set to GOROOT (/usr/local/go) has no effect
GOARCH="amd64"
GOBIN="/usr/local/go/bin"
GOCACHE="/Users/neusoft/Library/Caches/go-build"
GOEXE=""
GOFLAGS=""
GOHOSTARCH="amd64"
GOHOSTOS="darwin"
GOOS="darwin"
GOPATH="/usr/local/go"
GOPROXY=""
GORACE=""
GOROOT="/usr/local/go"
GOTMPDIR=""
GOTOOLDIR="/usr/local/go/pkg/tool/darwin_amd64"

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/z6/l24gc64j0jqf3rb23y732v640000gn/T/go-build639467550=/tmp/go-build -gno-record-gcc-switches -fno-common"

到此go语言安装成功，并且环境变量也配置成功，可以写简单的hello.go验证一下。

6、安装goland开发工具，下载地址：https://www.jetbrains.com/go/
7、安装完成后怎么激活？
