Problems running rails server

Question

I just installed the rails env using the Rails installer on my Mac OSX 10.7.4.

I create a project using the "rails new" command.

When I try to run the "rails server" command I get this message:

/usr/local/rvm/gems/ruby-1.9.3-p194/gems/rails-2.3.14/lib/rails_generator/options.rb:32:in `default_options': undefined method `write_inheritable_attribute' for Rails::Generator::Base:Class (NoMethodError)

When I run the $ ruby -v and $ gem -v, I get "ruby 1.9.3p194" and "1.8.24" respectively. What am I missing here? How can I get this server to run?

Answer 1

Install rails as a gem, gem install rails . As your are using rvm, the folder path displayed here shows rails 2.3.4, while you tried to run rails server . Check/change the rails version in your gem file and then do bundle install.

Answer 2

It looks like you are trying to use a Rails 3.x command with Rails 2.3. Pre 3.0 you have to use the server script.

From within your application directory run:

./script/server
