Rails 3 requires bundler to be installed, but bundler can’t be installed on Debian lenny because the gem version 1.2 is too old, an attempt update is also failed, any idea? # gem update --system ERROR: While executing gem … (RuntimeError) gem update --system is disabled on Debian. RubyGems can be updated using the official Debian repositories by aptitude or apt-get. ---

Several: 1. don’t use Debian 2. don’t rely on _any_ brain-dead, perpetually out-of-date package management system 3. remove anything ruby/rails-related from your system and install fresh from source At least, that’s what I would do… 🙂 – Hassan S. ------------------------ removed\_email\_address@domain.invalid twitter: @hassan ---

Au contraire - I see so many cases of people struggling with problems directly caused by “the Debian way” of packaging 3rd-party software (not just Ruby-related). The OP’s problem is exactly that; pointing it out is hardly a “troll”. – Hassan S. ------------------------ removed\_email\_address@domain.invalid twitter: @hassan ---

Hassan, so you deploy your applications on a macbook pro, do you? Nine out of ten apps are deployed onto a Linux machine; the majority of those are Ubuntu(Of course, Debian based). That means you need to figure out how to make rubygems work nicely there. You can install rubygems from source, or you can install upgrade\_rubygems which essentially does the same thing. Both of these circumvent the package management system; not a good idea. The correct way to do it is to use backports. For Debian you can get to rubygems 1.3.4 by using this backport: [Debian -- Error](http://packages.debian.org/lenny-backports/rubygems1.8) (1.9 is also available) Instructions on how to do it: [http://www.backports.org/dokuwiki/doku.php?id=instructions](http://www.backports.org/dokuwiki/doku.php?id=instructions) Foing outside the package management system is almost always a bad move. As soon as you do that it is much more difficult to backup and replicate that machine. Hope this helps -Jeremy On Sat, Feb 27, 2010 at 11:52 AM, Hassan S. \< ---

Well, that’s where we disagree; I don’t use the package management system for anything specific to my application. I certainly don’t need someone else determining that I should run some down-level hacked up version of the software I want. And I see no reason that implies any problems with either backup or replication of a system. At least, that hasn’t been my experience. ## YMMV!
