rails -v ?

I am using rails version 3.0.3 and ruby 1.9.2.p0

6

you are using rails 3.0.3 and ruby 1.9.2.p0

and please can you tell me the application version which you have to run is that also on rails 3 or on the lower version

7

Could you add this line

puts @loaded_stacks.inspect; puts [gem.name](http://gem.name)

right above line /home/.rvm/rubies/ruby-1.9.2-p0/lib/ruby/1.9.1/rubygems.rb:228, run this again, and paste the output here. Also, could you give us the output of “gem list”?

8

Here is the output of @loaded_stacks.inspect {"railties"=>, "rake"=>[#<Gem::Specification name=railties version=3.0.3>], "thor"=>[#<Gem::Specification name=railties version=3.0.3>]}

gem.name gives activesupport

My original application is on rails version 2.3.x but i need to run with rails 3.0.3 and ruby 1.9.2p0.

which thing i am missing?

9

you are using rvm please install ruby of lower version can be 1.8.7 if your config/enviroment.rb show rails version is > 2.3.2 else 1.8.6

then install rails 2.3.X as you required

gem install -v 2.3.x rails
