Hi all,

I just copied a small project from my computer to my vps. When I try to run rake db:migrate I get the error:

"Could not find RubyGem sqlite3-ruby (\>= 0)"

Here's the output with trace:

I do have sqlite3-ruby installed though. Any suggestions?

Thanks a lot, Eddie

Problem solved.

I was using ruby 1.9.1. I deleted all my gems and reinstalled everything with 1.9.2, and now it all work.

Hello,

I had the same problem for a long time, and every forumtopic was quite old, only solved for Ruby1.8+Rails2.3.X. Finally I solved this way: installed RVM, with that I upgraded to Rails 3, set Ruby1.9 as default, then: gem install sqlite3,

and in the Rails app I created, in the Gemfile: gem 'sqlite3-ruby', :require =\>'sqlite3' then bundle install, update... you will find your way.

Anyway may I ask your Ruby, Rails, Gem versions, and which OS you use? Feel free to write me private if it still doesn't want to work. Cheers, Zoltán
