I am writing a Ruby script, and I would like to use wordNet to stem String. I want to give it a string that may contain words of the same form and get back the string but after stemming it. I came across Ruby-WordNet and installed wordnet gem and wordnet-defaultdb gem. I also installed Sequel since it is required.
However, I am not sure how to deal with it. When I typed in the script:
require 'rubygems'
require 'sequel'
require 'wordnet'
I get the following error:
/Users/arwa/.rvm/rubies/ruby- 2.2.1/lib/ruby/site_ruby/2.2.0/rubygems/specification.rb:2112:in `raise_if_conflicts': Unable to activate wordnet-1.0.0, because sequel-4.24.0 conflicts with sequel (~> 3.38) (Gem::ConflictError)

If I removed
require 'sequel'
I get the following error:

I am not sure what is the problem and how to deal with it.
Does any one have any idea on how it works?
Also, if someone can direct me to a place where I can find example on how to code it and to deal with it.
Many thanks in advance.
The error says you have a version conflict.
See what gem list sequel --all says. Odds are good you loaded only the latest version of Sequel by using gem install sequel without specifying the version, or that you have two versions, the one specified by WordNet and the latest
Try removing/uninstalling all Sequel versions installed and reinstall only the specific version:
gem install sequel -v3.38
You can also try modifying the gem requirements for WordNet to not require a specific version of Sequel. Sequel is extremely stable so that should be a safe move.
