源代码安装go

安装Mercurial

如何在Ubuntu上安装Mercurial？

sudo apt-get install python2.5
sudo apt-get install python-all-dev
sudo apt-get install python-setuptools
sudo easy_install -U mercurial
hg --version

安装GO

hg clone -u release https://code.google.com/p/go ~/dist
cd go/src
./all.bash

运行all.bash后，出现“ALL TESTS PASSED” 说明安装成功

在~/.bashrc文件中增加以下

export GOROOT=~/dist
export GOBIN=$GOROOT/bin
export PATH=$PATH:$GOBIN

测试是否可以用命令中运行 #go

    gopath      GOPATH environment variable
    importpath  import path syntax
    packages    description of package lists
    testflag    description of testing flags

Use "go help [topic]" for more information about that topic.

官方有一种更简单的方式安装
1.下载go源代码

wget http://go.googlecode.com/files/go1.2.linux-amd64.tar.gz

2.解压到/usr/local 目录下

tar -C /usr/local -xzf go1.2.linux-amd64.tar.gz

3.增加到PATH中
在/etc/profile或者 $HOME/.profile中增加

export PATH=$PATH:/usr/local/go/bin

4.运行go测试是否成功
