gem update problem

Hello!

I cannot force a new application to run, it cannot update gems to the required version. Could you suggest a solution?

$ lsb_release -a No LSB modules are available. Distributor ID: Ubuntu Description: Ubuntu 7.10 Release: 7.10 Codename: gutsy $ ruby -v ruby 1.8.6 (2007-06-07 patchlevel 36) [i486-linux] $ gem -v 1.2.0

$ sudo gem install rubygems-update Successfully installed rubygems-update-1.3.1 1 gem installed $ sudo gem update --system Updating RubyGems Nothing to update $ script/console Rails requires RubyGems >= 1.3.1 (you have 1.1.0). Please `gem update --system` and try again.

after installing rubygems-update, just run   sudo update_rubygems

No success :frowning: $ sudo update_rubygems sudo: update_rubygems: command not found $ sudo update-rubygems sudo: update-rubygems: command not found

well, that's odd.   gem list should show you   rubygems-update (1.3.1) with that there should be the command   update_rubygems available. if not check your gem-directory which can be found by running   gem environment

for me it is "/usr/lib/ruby/gems/1.8/gems/rubygems-update-1.3.1/bin/ update_rubygems"

Ah, I guess the problem is in the paths! I have changed the standard "gem" command to work by default with Passenger. So, I guess, I should update the Passenger now?

Here is an output of your commands:

$ gem list -l ... rubygems-update (1.3.1) ... $ gem environment RubyGems Environment:   - RUBYGEMS VERSION: 1.2.0   - RUBY VERSION: 1.8.6 (2008-08-08 patchlevel 286) [i686-linux]   - INSTALLATION DIRECTORY: /opt/ruby-enterprise-1.8.6-20080810/lib/ ruby/gems/1.8   - RUBY EXECUTABLE: /opt/ruby-enterprise-1.8.6-20080810/bin/ruby   - EXECUTABLE DIRECTORY: /opt/ruby-enterprise-1.8.6-20080810/bin   - RUBYGEMS PLATFORMS:     - ruby     - x86-linux   - GEM PATHS:      - /opt/ruby-enterprise-1.8.6-20080810/lib/ruby/gems/1.8   - GEM CONFIGURATION:      - :update_sources => true      - :verbose => true      - :benchmark => false      - :backtrace => false      - :bulk_threshold => 1000      - :sources => ["RubyGems.org | your community gem host, "http:// gems.github.com"]   - REMOTE SOURCES:      - http://gems.rubyforge.org/      - http://gems.github.com

  - GEM PATHS:      - /opt/ruby-enterprise-1.8.6-20080810/lib/ruby/gems/1.8

you should find the rubygems-update gem there. just go in, locate the bin-directory and start update_rubygems from there.

still, to save yourself some trouble. look into your path-variables and make sure everything is working correctly. otherwise you'll be back here very soon with an other issue.

Exactly, check your paths, or link the standard ruby, gem and rails commands to the desired version...

Cheers, Sazima

It's very strange, but I still cannot force the update_rubygems to run correctly. I have tried the full path, but failed:

$ sudo /opt/ruby-enterprise-1.8.6-20080810/lib/ruby/gems/1.8/gems/ rubygems-update-1.3.1/bin/update_rubygems Error: Cannot find RubyGems Update Path! RubyGems has already been updated. The rubygems-update gem may now be uninstalled. E.g. gem uninstall rubygems-update

And I have found a similar problem here: RubyGems 1.1.1 - Ruby - Ruby-Forum But unfortunately no new solution....

Have you tried downloading the rubygems 1.3.1 source from http://rubyforge.org/frs/?group_id=126 , unpacking, then running "ruby setup.rb" as root in that directory?
