在heroku Cedar上的CSV

Question

我想在heroku雪松上使用带有rails 3.2.1的CSV模块,但是

require 'CSV'

不起作用

这是使用控制台测试时的错误:

Loading production environment (Rails 3.2.1)
irb(main):001:0> require 'CSV'
LoadError: no such file to load -- CSV
    from /app/vendor/bundle/ruby/1.9.1/gems/activesupport-3.2.1/lib/active_support/dependencies.rb:251:in `require'

Answer 1

尝试

require 'csv'

这是区分大小写的.

更新:这不是一个Heroku问题提醒你 - 如果你在本地做同样的事情,你会得到同样的恐怖.CSV位于Ruby 1.9的标准库中.
