Hi Guys, I am new to Ruby and currently trying to develop an existing Ruby project (Sinatra based framework) in my company I have installed the pre-requisites to rake and rackup,but only to find this conflicts "..ruby/2.0.0/rubygems/specification.rb:1990: in 'raise_if_conflicts': Unable to activate sinatra-contrib-1.4.0, because sinatra-1.2.6 conflicts with sinatra <~> 1.4.2> (Gem:: LoadError) " Sounds like even though I have the latest version somehow something is still using the old version, how do I fix this please? Thank you! Attachments: http://www.ruby-forum.com/attachment/8572/error.jpg -- Posted via http://www.ruby-forum.com/.
