Answer 1

Try including tzinfo-0.3.24 in your Gemfile and doing bundle exec with the command that gives you the error. Alternatively you could bundle install --development to get the Gems in the vendor folder. Let us know how you get on.

Answer 2

After DLL Hell we have Gem Hell. It looks like we have the same dependency hell in Ruby as in other communities. Welcome :-)

The gem tzinfo with the right version 0.3.24 seems to be missing, or it is not referenced correctly in your Gemfile. Check your Gemfile and your Gemfile.lock. The latter is useful to find out dependencies, and it should be updated if the Gemfile is changed (by running a bundle install).

If you have installed the gems locally, by using gem install --user-install gemname or bundle install --path ~/.gem , then you maybe have multiple gems in multiple locations. Check out the GEM PATHS by calling a gem env command from the command line.

And by the way, you seem to use Rails 3.0.x with the old mysql gem. The mysql2 gem is now the default in Rails 3. I would recommend to use the mysql2 gem instead by adding gem 'mysql2' to the GemFile and by using using the mysql2 adapter in your database.yml .
