Reporting errors in launching rails webrick server

Question

I have an application which runs on rails 2.3.2 and now i upgraded my version of rails to 3.0.3

After i try to start the application server by typing rails server

I get a list of arguments that i should pass to the command. This suggests the server did not start successfully. However, where can i get a list of the errors encountered in starting rails server ?

Also, i am using RVM for managing rails versions. However, even after changing the current running version of rails, radrails is still using the old version of rails. How can i instruct radrails to use the current system rails version ?

Answer 1

Those are not errors, it's the output of the "rails" command from rails 2.3.x

You created a new rails project called server in the directory where u ran the command.

Check the gemset on rvm and see if you're using the correct rails version and check the config/environment.rb in your application and see if your application is using rails 3.

You can see it in RAILS_GEM_VERSION

Answer 2

The output you're seeing suggests that the rails binary you're executing is for 2.3.x, not rails 3.0.0. Try rails --version. My guess is that you just need to run gem install rails.
