Require - not loading gem

Ruby
1

Hi,

I have installed the spreadsheet gem to read and write MS Excel files.

I have a problem in that when I run the app from the command line I
get the error: unable to load spreadsheet

However, when I run my Cuke features and RSpec tests, the gem is
loaded up fine, and xls files are read and written as intended - it is
only a problem when I run the app directly from the command line.

I presume this is a problem with my ruby installation, or environment.
I have looked through the Pickaxe book ref Environment, but culdn’t
find anything to help - and I can’t find anything on the site for the
gem in respect of any support, so if someone could point me in the
right direction, I’d be eternally grateful.

Ubuntu 10.04
Ruby 1.8.7

App structure:

[application root folder]
[bin]
application (chmod +x)
[lib]
application.rb (all require statements in here)
[application]
…
modules
[features]
…
cuke feature files
[spec]
…
RSpec spec files

If anyone can help I’d appreciate it. At the moment, I can only run
the app via Cucumber or RSpec, and I need to run it directly from the
command line.

Thanks

Paul

You must manually require rubygems in 1.8.x. In 1.9.x this is no longer
necessary. Either add require ‘rubygems’ before require ‘spreadsheet’
or run the program with ruby -r rubygems.

I suspect the reason it works from rspec/cucumber is because there are
themselves gems and must require rubygems to operate.
