I have the same issue with Bundler 1.0.2 but it works with an older version.

It only happens on deployment to Ubuntu - locally it works fine on Mac OS X

Here's the error:

[myserver.com] executing command

*** [deploy:update_code] rolling back

And my Gemfile is short:

source 'http://rubygems.org'

group :rake do
gem 'rake' gem 'capistrano' end

group :test do
gem 'rack' end

group :rake, :test do
gem 'rspec', '2.0.0.rc'

if RUBY_PLATFORM =~ /darwin/

gem 'ruby-debug-base19', '0.11.24'
gem 'ruby-debug19', '0.11.6'

end end

And my Rakefile even shorter

require "rubygems"
require "bundler"
Bundler.setup(:default, :rake)
require "rake"

RubyGems is 1.3.7

I'll try to debug it a little more tonight.

Oh, and:

Ubuntu 10.04
Ruby 1.9.1, which is the latest available via Ubuntu's apt-get repository at this point in time, which, when running rails gets flagged:

$ rails --version

    Rails 3 doesn't officially support Ruby 1.9.1 since recent stable
    releases have segfaulted the test suite. Please upgrade to Ruby 1.9.2
    before Rails 3 is released!

    You're running
      ruby 1.9.1p378 (2010-01-10 revision 26273) [i486-linux]

Rails 3.0.1

Yeah, it's true that Rails 3 doesn't maintain support for Ruby 1.9.1. Please try upgrading to 1.9.2 and see if the error goes away.

Installing from ftp.ruby-lang.org seems to have fixed the problem for me. Although there were a few headaches.

I uninstalled Ruby via the Ubuntu Synaptic package. I also uninstalled Rails with gem uninstall.

After installing Ruby 1.9.2, I then installed Rails with gem install rails. The install seemed to run fine. But when I tried to run the rails command I got an error:

 /usr/bin/ruby1.9.1: bad interpreter: No such file or directory

I checked and found that /usr/bin/rails has a line specifying ruby1.9.1

#!/usr/bin/ruby1.9.1

This file was being run instead of /usr/local/bin/rails which says:

#!/usr/local/bin/ruby

I deleted /usr/bin/rails so that /usr/local/bin/rails ran instead.

Sorry, that previous post got submitted prematurely.

Then the bundle command then ran successfully:

Your bundle is complete! Use bundle show [gemname] to see where a bundled gem is installed.

HTH.

BTW, why does the "WATCH" button appear in the second posting of the thread?

I had a hell of a time finding it, because that doesn't seem like the logical place it should be found....

This is an issue with bundler, and they are saying that 1.9.1 is not officially supported. You can fix it by suppressing the Gem::QuickLoader.load_full_rubygems_library call in bundler/rubygems_ext.rb with something like.

  Gem::QuickLoader.load_full_rubygems_library unless RUBY_VERSION.eql?('1.9.1')

The bug for this issue lives over on github. I recommend marking this invalid.

This issue has been automatically marked as stale because it has not been commented on for at least three months.

The resources of the Rails core team are limited, and so we are asking for your help. If you can still reproduce this error on the 3-0-stable branch or on master, please reply with all of the information you have about it and add "[state:open]" to your comment. This will reopen the ticket for review. Likewise, if you feel that this is a very important feature for Rails to include, please reply with your explanation so we can consider it.

Thank you for all your contributions, and we hope you will understand this step to focus our efforts where they are most helpful.

I experience this same behavior, although I'm not using rails at all. I'm running ruby 1.9.1-p378 and bundler 1.0.10. Looks like this has nothing to do with rails.
