I am using rails 3 on ubuntu 10. When i trying to load rails development environment using Rails Runner command i am getting this: Usage: runner [options] (''Some.ruby(code)'' or a filename) -e, --environment=name Specifies the environment for the runner to operate under (test/development/production). Default: development -h, --help Show this help message. You can also use runner as a shebang line for your scripts like this: ------------------------------------------------------------- #!/usr/bin/env /root/workspace/anurag/script/rails runner Product.all.each { |p| p.price *= 2 ; p.save! } ------------------------------------------------------------- I also tried rails console command then i get this error: usr/local/lib/ruby/1.9.1/irb/completion.rb:9:in `require'': cannot load such file -- readline (LoadError) from /usr/local/lib/ruby/1.9.1/irb/completion.rb:9:in `<top (required)>'' from /usr/local/lib/ruby/gems/1.9.1/gems/railties-3.2.0/lib/ rails/ commands/console.rb:3:in `require'' from /usr/local/lib/ruby/gems/1.9.1/gems/railties-3.2.0/lib/ rails/ commands/console.rb:3:in `<top (required)>'' from /usr/local/lib/ruby/gems/1.9.1/gems/railties-3.2.0/lib/ rails/ commands.rb:38:in `require'' from /usr/local/lib/ruby/gems/1.9.1/gems/railties-3.2.0/lib/ rails/ commands.rb:38:in `<top (required)>'' from script/rails:6:in `require'' from script/rails:6:in `<main>'' Anyone please tell how to load Development environment. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
