first, you can debug the shell in the console until success.  
and you can write the shell in sh file,like this:

run.sh:  
export RAILS\_ENV=production  
/usr/bin/ruby ~/1.rb  
…

crontab file

- 
  - 
    - 
      - 
        - sh ~/run.sh

There are several things in Rails that assumes the current working  
directory  
is somewhere in the Rails application directory structure. For example,  
the  
following works also:

- 
  - 
    - 
      - 
        - cd /mnt/apps/NearbyAd/current/lib; …/script/runner -e  
production camp.rb
