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

from script/rails:6:in `<main>'
Anyone please tell how to load Development environment.
