 gvm是第三方开发的Go多版本管理工具，类似ruby里面的rvm工具。使用起来相当的方便，安装gvm使用如下命令：
 ```sh
 
-	bash < <(curl -s -S -L https://raw.githubusercontent.com/moovweb/gvm/master/binscripts/gvm-installer)
+bash < <(curl -s -S -L https://raw.githubusercontent.com/moovweb/gvm/master/binscripts/gvm-installer)
 ```
 安装完成后我们就可以安装go了：
 ```sh
 
-	gvm install go1.8.1
-	gvm use go1.8.1
+gvm install go1.8.3
+gvm use go1.8.3
 ```
 也可以使用下面的命令，省去每次调用gvm use的麻烦：
-        gvm use go1.8.1 --default
+        gvm use go1.8.3 --default
 
 执行完上面的命令之后GOPATH、GOROOT等环境变量会自动设置好，这样就可以直接使用了。
 
 ### apt-get
 Ubuntu是目前使用最多的Linux桌面系统，使用`apt-get`命令来管理软件包，我们可以通过下面的命令来安装Go，为了以后方便，应该把 `git` `mercurial` 也安装上：

-	sudo add-apt-repository ppa:gophers/go
-	sudo apt-get update
