I am running Ruby 1.9.1 & rails 2.3.8. Everything is installed fine as far

  • 0

I am running Ruby 1.9.1 & rails 2.3.8. Everything is installed fine as far as I can tell but when I run rake db:migrate I get this error:

Missing the Rails 2.3.8 gem. Please gem install -v=2.3.8 rails, update your RAILS_GEM_VERSION setting in config/environment.rb for the Rails version you do have installed, or comment out RAILS_GEM_VERSION to use the latest version installed.

So I wanted to make sure I had rails installed and ran from the command line rails -v & it says Rails 2.3.8. So I am not sure what gives here. Can anyone point me in the right direction? thank you very much.

    Well, if you really have those versions installed and you get the error, something may be wrong.

    But, you can do as the message recommends and comment out the setting in your config/environment.rb so it tries to use whatever version you have installed.
