Mac上go環境配置

使用Homebrew 安裝go語言sdk

brew install go

==> Downloading https://homebrew.bintray.com/bottles/go-1.5.1.el_capitan.bottle.
Already downloaded: /Library/Caches/Homebrew/go-1.5.1.el_capitan.bottle.tar.gz
==> Pouring go-1.5.1.el_capitan.bottle.tar.gz
==> Caveats
As of go 1.2, a valid GOPATH is required to use the go get command:
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/go/libexec/bin
==> Summary
? /usr/local/Cellar/go/1.5.1: 5330 files, 273M

配置GOPATH

查看go 的環境變量設置

go env

GOARCH="amd64"
GOBIN=""
GOEXE=""
GOHOSTARCH="amd64"
GOHOSTOS="darwin"
GOOS="darwin"
GOPATH=""
GORACE=""
GOROOT="/usr/local/Cellar/go/1.5.1/libexec"
GOTOOLDIR="/usr/local/Cellar/go/1.5.1/libexec/pkg/tool/darwin_amd64"
GO15VENDOREXPERIMENT=""
CC="clang"
GOGCCFLAGS="-fPIC -m64 -pthread -fno-caret-diagnostics -Qunused-arguments -fmessage-length=0 -fno-common"
CXX="clang++"
CGO_ENABLED="1"

需要設置環境變量GOPATH ,GOBIN 以及把GOBIN加入到PATH中

在fishshell設置GOPATH
set -gx GOPATH /usr/local/Cellar/go/1.5.1

vim .bash_profile

export GOPATH=/usr/local/Cellar/go/1.5.1
export GOBIN=$GOPATH/bin
export PATH=$PATH:$GOBIN

source .bash_profile

再看下go的環境變量

go env

GOARCH="amd64"
GOBIN="/usr/local/Cellar/go/1.5.1/bin"
GOEXE=""
GOHOSTARCH="amd64"
GOHOSTOS="darwin"
GOOS="darwin"
GOPATH="/usr/local/Cellar/go/1.5.1"
GORACE=""
GOROOT="/usr/local/Cellar/go/1.5.1/libexec"
GOTOOLDIR="/usr/local/Cellar/go/1.5.1/libexec/pkg/tool/darwin_amd64"
GO15VENDOREXPERIMENT=""
CC="clang"
GOGCCFLAGS="-fPIC -m64 -pthread -fno-caret-diagnostics -Qunused-arguments -fmessage-length=0 -fno-common"
CXX="clang++"
CGO_ENABLED="1"

環境變量設置成功!
