为什么运行下面显示的代码会出错？(它用于Coursera的Stanford'Startup engineering'课程中的一个作业:https://class.coursera.org/startup-001/quiz/attempt ？ quiz_id = 149 )

这个课程是在2013年6月 - 6月进行的,所以可能有节点或csv的更新可能会打破脚本吗？作业不是关于修复脚本,所以这个问题不是'作弊',而且课程目前还没有运行..

因此,环境是:Ubuntu 14.04(内核3-13-0-29-通用),节点v0.11.13,npm v1.4.9

我npm install在主目录中有'csv,accounting util和restler,脚本也在那里.

这让我完全难过...... :-(
