安装并配置golang

通过brew安装golang

• 首先看看有哪些golang版本可用

我们发现最新的有1.9可以使用

• 安装brew下最新版本的go

fabric:~ fabric$ brew install [email protected]
Updating Homebrew...
==> Downloading https://homebrew.bintray.com/bottles/[email protected]_sierra.bottle.tar.gz
######################################################################## 100.0%
==> Pouring [email protected]_sierra.bottle.tar.gz
==> Caveats
A valid GOPATH is required to use the `go get` command.
If $GOPATH is not specified, $HOME/go will be used by default:
  https://golang.org/doc/code.html#GOPATH

You may wish to add the GOROOT-based install location to your PATH:
  export PATH=$PATH:/usr/local/opt/[email protected]/libexec/bin

This formula 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 this software first in your PATH run:
  echo 'export PATH="/usr/local/opt/[email protected]/bin:$PATH"' >> ~/.bash_profile

==> Summary
  /usr/local/Cellar/[email protected]/1.9.7: 7,668 files, 294.2MB

• 配置golang的相关环境变量

fabric:~ fabric$ vim ~/.bashrc

将下面内容添加进上面的文件

#GOROOT
export GOROOT=/usr/local/opt/go\@1.9

#GOPATH
export GOPATH=$HOME/Documents/code/gopath

#GOPATH root bin
export PATH=$PATH:$GOROOT/bin

GOPATH可以根据个人习惯设置为其他目录
本人习惯在home目录下的Documents里新建一个code目录，用于存放各种语言的代码，比如Documents/code/gopath用于存放golang的代码，Documents/code/www用于存放php代码...

让改动生效

fabric:~ fabric$ source ~/.bashrc

• 试一试golang是否安装成功
  出现以下内容，则安装成功

fabric:~ fabric$  go env
GOARCH="amd64"
GOBIN=""
GOEXE=""
GOHOSTARCH="amd64"
GOHOSTOS="darwin"
GOOS="darwin"
GOPATH="/Users/fabric/Documents/code/gopath"

后来发现每次终端打开要使用 golang 的时候都需要执行 source ~/.bashrc 命令，为了解决这个问题：

vim ~/.bash_profile 在文件加入下面内容

#加载.bashrc文件 是为了解决每次打开终端都要执行source ~/.bashrc命令 go的配置才生效的问题
if test -f .bashrc ; then
source .bashrc
fi
