ubuntu14.04通过 gvm 安装 go语言开发环境

最近用回了ubuntu ，所以打算安装golang学习当下比较火热的这个语言

本来打算使用 sudo apt-get install golang的　安装后发现　是１．２．１不是最新版

所以上网上搜了一下。在git上找到一个叫做 gvm的东东，是golang版本管理器

地址：https://github.com/moovweb/gvm

１　第一步　如果你用的是Ｕｂｕｎｔｕ　需要提前安装一些库

执行：　

sudo apt-get install curl git mercurial make binutils bison gcc build-essential　

２　如果你用的是bash shell ，默认你没有按过别的shell ，一般都用的bash shell

执行： 

bash < <(curl -s -S -L https://raw.githubusercontent.com/moovweb/gvm/master/binscripts/gvm-installer)

3 终端显示如下 表示安装好了

Cloning from https://github.com/moovweb/gvm.git to /home/c3t/.gvm
Created profile for existing install of Go at "/usr/lib/go"
Installed GVM v1.0.22

Please restart your terminal session or to get started right away run
 `source /home/c3t/.gvm/scripts/gvm`

5上面 第5行告诉你重启终端 执行

source /home/c3t/.gvm/scripts/gvm

6 然后我们安装一个golang ，安装默认的版本，时间有点长

执行 ，

gvm install go1 

 7 编译时报错，暂时不知道什么原因

8  所以使用以下命令安装,1.4是最新版,但是安装失败了。

gvm install 1.4 -B 

９　最后下载　golang的sdk　然后在ｐａｔｈ下配置环境变量
