本文主要对前人所写文章的总结，包括自己在安装nodejs 和express过程中遇到的问题。以备后用，同时能让正在学习node的人少走一些弯路。

\n\n

1.安装环境，由于对linux是菜鸟级别，所以在虚拟机上安装的一个ubuntu11.10 随便玩玩，虚拟机的安装这里就不多说了。

\n\n

2.node.js安装：\n第一步，安装依赖包，

\n\n

sudo apt-get install g++ curl libssl-dev apache2-utils\nsudo apt-get install git-core\n

\n\n

第二步，获取node源码

\n\n

git clone git://github.com/joyent/node.git\n

\n\n

下载完成之后进入cd node 进入node文件夹，

\n\n

第三步：指定迁出版本：git checkout v0.4.10 ,git是一个版本管理工具，这个我们用git迁出0.4.10版本，如果不迁出的话直接进行编译安装将会安装node最新版0.5.5-pre。最新版对很多常用的包是不支持的。比如express，所以这个地方一定要注意。

\n\n

第四步：制定路径，执行编译

\n\n

$ mkdir ~/local      当前用户的home目录创建文件夹\n$ 进入到解压后的configure文件夹中执行./configure --prefix=$HOME/local/node  制定编译路径\n$ make           编译。\n$ sudo make install 安装。\n$ echo ‘export PATH=$HOME/local/node/bin:$PATH’ >> ~/.profile 设置环境变量\n$ echo ‘export NODE_PATH=$HOME/local/node:$HOME/local/node/lib/node_modules’ >> ~/.profile   设置NODE_PATH\n$ source ~/.profile\n

\n\n

到现在我们就可以运行node -v来查看是否安装成功了。注意这里的环境变量的设置只是临时的。

\n\n

第五步：设置永久环境变量，

\n\n

设置永久环境变量即使重启机器也能够使用node命令了。进入/etc vi profile在最后面追加两行：

\n\n

export PATH=”$HOME/local/node/bin:$PATH”\nexport NODE_PATH=”$HOME/local/node:$HOME/local/node/lib/node_modules”\n

\n\n

ok。至此 node.js安装完成。

\n\n

3.express 安装

\n\n

安装npm ：\n执行命令：

\n\n

curl http://npmjs.org/install.sh | sh\n

\n\n

安装express：

\n\n

npm install express -gd\n

\n\n

-g代表安装到NODEPATH的lib里面，而-d代表把相依性套件也一起安装。如果沒有-g的话会安装目前所在的目录(会建立一个nodemodules的文件夹)

\n\n

执行express -v 查看是否安装成功。到此express 已经安装完成。

\n\n

在任意目录下执行express xxx 就会创建一个node.js +express项目了。
