Trying to get ruby on rails 1.8.7 working on windows but when i start rails server i get this error:

`require': no such file to load -- sqlite3/sqlite3_native (LoadError)

I have tried copying the 3 sqlite files and putting them in ruby/bin but it doesnt help as mentioned at the bottom of this post: http://www.ruby-forum.com/topic/216270

Any ideas?

Rails 3.0.6 | Ruby 1.8.7 | Windows 7

Have you installed the sqlite3 gem with "gem install sqlite3-ruby"? I actually don't have any experience running Rails on Windows, but I always almost forget to do this when setting up the Rails development environment on a new machine.

If you're on Rails 3, then all you should need do is
1. add it to your Gemfile
   gem 'sqlite3', '1.3.3', :require => 'sqlite3'
(I have the version number because I don't want random upgrades on my gems)
2. run
  bundle install
and it will take care of installing it for you.

Bundler is your friend when it comes to gems...

Ah, windows... Try this point (a bit old, but looks reasonable) http://blog.emson.co.uk/2008/06/installing-sqlite3-on-windows-for-rails/

Or this one which is specific to Rails3: http://accidentaltechnologist.com/ruby-on-rails/running-rails-3-on-windows/

Found the solution on this post's comments http://www.shaunambrose.com/2010/08/05/how-to-fix-a-sqlite3-dll-missing-error-message-in-ruby-on-rails/comment-page-1/#comment-15965

"The problem seems to be that the sqlite3 gem is compiled with version 3.7.3. I downloaded and set up version 3.7.3 instead and it now works just fine."
