You're running a version of ruby with no Readline support

Please `gem install rb-readline` or recompile ruby --with-readline.

Tried 'gem install rb-readline' but still issue is there.

Answer 1

I guess you'll need to add this gem to a Gemfile as well. Then run bundle install

If you do not have Gemfile, then you'll need to run rake gems:install like described in relevant guide

Answer 2

I think you need to install that missing gem to your system first.

For that you have to run the code in command line 'gem install GEME NAME'

After that still that error comes then you have to add that gem in conf/environment.rb where gem list present because the application has rails 2.3.18.
