Rails doesn't find installed gem on server startup

rubyonrails-talk

Hi,

I have a ruby application that I need to install but I'm new to ruby on rails and I've run into a problem already...

I've installed Ruby 1.8.7, RubyGems 1.5.3 and Rails 2.3.8. These are the versions required for the application.

I have also installed all the gems specified in the application's .gem file using "$ gem install ..." Required gems : haml jrails rails -v 2.3.8 pg heroku_deploy money validates_email_format_of mogli facebooker2 simple_uuid delayed_job ssl_requirement recaptcha hoptoad_notifier

When I launch the server executing "$ ruby script/server" from the application's directory I get the following message :

2

So I found the solution…

Missing these required gems: delayed_job < 2

means that the application requires the delayed_job gem with a version less than 2 : as specified in the environment.rb :

config.gem ‘delayed_job’, :version => “<2”

I just had to install a previous version of the delayed_job gem :

$ gem install delayed_job -v 1.8.5
