这几天在小小的学习下nodejs，按照博文
http://cnodejs.org/topic/5191d30e63e9f8a542bc2758
中所记载的一步一步来运行个简单的例子。
当做到 session 的使用 这一小节的时候，
按照博文中的步骤下载session-mongoose 依赖库：
npm install session-mongoose

在下载过程中需要build，在build的时候提示：
Could not load the Visual C++ component "VCBuild.exe"
无视之、、、
再重新编译运行例子的js代码，提示如下错误：
events.js:72
throw er; // Unhandled 'error' event
^

搜了下发现原来是需要安装mongodb，于是转到mongodb下载页面.
由于我的开发环境是：
Win7 64-Bit English Version.
于是就按照mongodb文档 Install MongoDB on Windows 在本机进行安装。
安装完毕，启动mongodb：
c:\sap\java\db\mongdb>mongodb-2.4.8\bin\mongod.exe --dbpath c:\sap\java\db\mongdb\data
完了之后再次运行express 的例子，测试运行通过。
