What I have installed until now is:

  1. Latest JDK and JRE (version 7 update 6)
  2. jRuby 1.7.0 preview 2

and successfully tested them.

Then I try the following command: 

jruby -S gem install -y rails

and get the following error:

ERROR: While executing gem ... <RuntimeError>
    Unknown command itall

Please advice, what I have to do in order to install rails on jruby. My OS is windows pro (32 bits).

EDIT: Also note that I have not install any other thing - Ruby for example.

  • Would you meant "Unknown command install" instead of "Unknown command itall" ? - Please check: "jruby -S gem ENV" and report here the output you get – Franco Rondini Aug 25 '12 at 22:08

    When I remove the '-y' part of the command the install happened. – gotqn Aug 26 '12 at 07:29

Removing the '-y' part of the command fix the issue.
