第一步：安装依赖包

\r\n
1. 安装python 2.6版或者更高（ubuntu默认都已安装，可以在terminal中使用 pyhton -v 命令查看python版本）。\r\n
2. 安装其他依赖包:\r\n
sudo apt-get install g++ curl libssl-dev apache2-utils\r\n
3. 安装git工具：\r\n
sudo apt-get install git-core\r\n

第二步：获取源码

\r\n
git clone git://github.com/joyent/node.git\r\n
等待下载完成，大小为20+m。\r\n

第三步：指定编译版本，重要！

\r\n
1.先进入存放下载源码的文件夹：\r\n
cd node\r\n
2. 指定迁出版本：\r\n
git checkout v0.4.10\r\n
这里非常重要，因为目前最新的node版本为0.5.5-pre，但是很多常用的包仅支持到0.4.10（比如express），所以如果使用最新版node的话，会导致npm无法下载相应的包。\r\n
3. 指定路径，编译执行:\r\n
mkdir ~/local\r\n
./configure –prefix=$HOME/local/node\r\n
make\r\n
make install\r\n
echo ‘export PATH=$HOME/local/node/bin:$PATH’ >> ~/.profile\r\n
echo ‘export NODE_PATH=$HOME/local/node:$HOME/local/node/lib/node_modules’ >> ~/.profile\r\n
source ~/.profile\r\n

第四步：设置环境变量

\r\n
如果想重启后还能继续直接使用node命令,那么需要设置环境变量:\r\n
使用命令 sudo gedit /etc/profile 打开配置文件，在文件最后中添加如下两行：\r\n
export PATH=”$HOME/local/node/bin:$PATH”\r\n
export NODE_PATH=”$HOME/local/node:$HOME/local/node/lib/node_modules”\r\n
保存后重启系统使设置生效。\r\n

第五步：安装npm

\r\n
curl http://npmjs.org/install.sh | sh\r\n
根据需要，安装相应的包，例如express：\r\n
npm install express\r\n
如果输入该命令后长时间没有反应，可以通过添加 -verbose参数查看执行的详细信息，即：\r\n
npm install express -verbose\r\n
一般情况下无法下载有两个原因：\r\n
1. 网速太慢，超时退出。\r\n
2. node的版本太新，当前下载的包不支持。（解决方法在第三步已说明。）\r\n

第六步：测试HelloWorld程序

\r\n
将以下代码保存为一个hello.js的文件\r\n

\r\n

\r\n
\r\n
\r\n
\r\n
\r\n
\r\n
\r\n
\r\n

\r\n

var

http = require(

'http'

);

\r\n

http.createServer(

function

(req, res) {

\r\n

res.writeHead(200, {

'Content-Type'

'text/plain'

});

\r\n

res.end(

'Hello Node.jsn'

);

\r\n

}).listen(8124,

\"127.0.0.1\"

);

\r\n

console.log(

'Server running at http://127.0.0.1:8124/'

);

\r\n

\r\n
然后使用命令：\r\n
node hello.js\r\n
启动服务。\r\n
打开浏览器，输入地址：http://127.0.0.1:8124/\r\n
如果返回 Hello Node.jsn 则安装成功！\r\n
