Golang
是Google开发的一种编译型,平行化,具备垃圾回收功能的编译语言,还和C同样有指针。Golang
是天生的网络编程语言,学习使用Golang
先从环境配置开始。
环境要求:html
Homerbrew
安装参考:http://brew.sh/golang
Golang
能够经过源代码本身编译安装https://golang.org/project/,为了管理和升级建议使用Homerbrew
安装。
使用命令行直接安装Golang
:shell
brew install go编程
==> Downloading https://homebrew.bintray.com/bottles/go-1.7.el_capitan.bottle.tar.gz ######################################################################## 100.0% ==> Pouring go-1.7.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=$PATH:/usr/local/opt/go/libexec/bin ==> Summary ? /usr/local/Cellar/go/1.7: 6,435 files, 250.6M
从提示中能够看出须要设置GOPATH
和GOROOT
的环境变量,以及设置PATH
.vim
查看go 的环境变量设置的命令api
go envbash
GOARCH="amd64" GOBIN="" GOEXE="" GOHOSTARCH="amd64" GOHOSTOS="darwin" GOOS="darwin" GOPATH="" GORACE="" GOROOT="/usr/local/Cellar/go/1.7.6/libexec" GOTOOLDIR="/usr/local/Cellar/go/1.7.6/libexec/pkg/tool/darwin_amd64" GO15VENDOREXPERIMENT="" CC="clang" GOGCCFLAGS="-fPIC -m64 -pthread -fno-caret-diagnostics -Qunused-arguments -fmessage-length=0 -fno-common" CXX="clang++" CGO_ENABLED="1"
须要设置的环境变量包括:GOPATH
,GOBIN
以及把GOBIN加入到PATH
中,GOROOT
变量默认已经设置好。网络
在fishshell
设置GOPATH:编程语言
set -gx GOPATH /usr/local/Cellar/go/1.7.6
学习
在bash
中设置:
vim .bash_profile
export GOPATH=/usr/local/Cellar/go/1.7.6 export GOBIN=$GOPATH/bin export PATH=$PATH:$GOBIN
使修改马上生效:
source .bash_profile
再看下go的环境变量:
go env
GOARCH="amd64" GOBIN="/usr/local/Cellar/go/1.7.6/bin" GOEXE="" GOHOSTARCH="amd64" GOHOSTOS="darwin" GOOS="darwin" GOPATH="/usr/local/Cellar/go/1.7.6" GORACE="" GOROOT="/usr/local/Cellar/go/1.7.6/libexec" GOTOOLDIR="/usr/local/Cellar/go/1.7.6/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"
环境变量设置完成!
