问题
I want to be able to deal with excel spreadhseets in rails.
So I am using the spreadsheet library.
However, when I use rubygems to install the spreadsheet, I get an exception:

My environments:

回答1:
Check your gems:
gem list
Check for that one being installed:
gem list | grep spreadsheet
Follow the instructions for use at http://rubygems.org/gems/spreadsheet which also talks about Development Dependencies:
hoe ~> 2.13
rdoc ~> 3.10
There is a great "getting started" guide at http://spreadsheet.rubyforge.org/files/GUIDE_txt.html
The wiki - http://spreadsheet.ch/ is also useful.
