Error :
boot.rb:20:Warning: Gem::SourceIndex#search support for String
patterns is deprecated
Fix :
There is a call to Gem Source Index in boot.rb:
‘Gem.cache.search’
Just replace ‘search’ with ‘find_name’ .
It should look something like this :
rails_gem = Gem.cache.find_name(`rails’,”=#{rails_gem_version}.0″).sort_by { |g| g.version.version}.last
