Unix下安装Go语言 超级方便，不多说了 直接上代码

mac下需要安装xcode才可以编译

另外安装brew 这个mac下的包管理软件也很方便

先安装Mercurial 包

<pre>sudo easy_install mercurial #安装hg 是 类似git的另一中版本管理软件
brew search go
brew install go
/usr/local/bin/hg==> Cloning http://go.googlecode.com/hg/
Updating /Users/darkhucx/Library/Caches/Homebrew/go--hg
pulling from http://go.googlecode.com/hg/
searching for changes
adding changesets
adding manifestsadding file changesadded 11 changesets with 56 changes to 44 files
(run 'hg update' to get a working copy)44 files updated, 0 files merged, 0 files removed, 0 files unresolved
==> Checking out revision release
==> ./all.bash/usr/local/Cellar/go/HEAD: 1797 files, 104M, built in 5.0 minutes
</pre>

编译完成，将go的路径加入 profile文件中去

mate ~/.profile
#go lang path
export PATH=/usr/local/Cellar/go/HEAD/bin:$PATH
source ~/.profile

完成go的安装，写段代码测试 

package main
import "fmt"
func main(){
	fmt.Printf("hello world,你好 世界\n")
}

6g hello.go #编译
6l hello.6
./6.out #完成
