Node.js配置好后，总要搞点啥吧，还是从山寨个微博开始。

1.express install

npm install expressnpm install -g express-generator@3//express 命令行从4.x开始单独分出一个模块，单独安装

2.搭建microblog

题外话，我是ubuntu 14.04 64位，

sudo apt-get install nodejs后/usr/bin下只有nodejs没有node,使用不方便，建个软连接sudo ln -s /usr/bin/nodejs /usr/bin/node

这样express命令行里可以运行了

express -t ejs microblog

create : microblog   create : microblog/package.json   create : microblog/app.js   create : microblog/public   create : microblog/public/javascripts   create : microblog/public/images   create : microblog/public/stylesheets   create : microblog/public/stylesheets/style.css   create : microblog/routes   create : microblog/routes/index.js   create : microblog/routes/user.js   create : microblog/views   create : microblog/views/index.jade   create : microblog/views/layout.jade   create : microblog/views/error.jade   create : microblog/bin   create : microblog/bin/www   install dependencies:     $ cd microblog && npm install   run the app:     $ DEBUG=my-application ./bin/www

不要忘了进入目录npm install因为还没装完

cd microblog && npm install

好了，运行下DEBUG=my-application ./bin/www
