I am trying to install rails on Ubuntu 10.04. So far, I’ve executed these commands:
apt-get install build-essential libapache2-mod-passenger apache2 rubygems ruby1.8-dev libopenssl-ruby
gem install fastthread
gem install rails
Fastthread installed easily. However, trying to install rails results in:
ERROR: Error installing rails:
bundler requires RubyGems version >= 1.3.6
So, I tried gem -v which returned 1.3.5.
How do I upgrade rubygems? apt-get won’t install above 1.3.5. And gem update --system results in:
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.
So right now I simply can’t install rails, because I need a newer version of rubygems, and ubuntu won’t let me upgrade my current version of rubygems.
As a side note, i tried installed rails via apt-get install rails which seemed to work, but I don’t see rails as a gem when i type gem list. What’s the deal with that?
Another note: The result of gem list is:
*** LOCAL GEMS ***

I assume installing rails via apt-get installed those gems? Prior to installing rails through apt-get I only had mysql and fastthread.
You have to manually install rubygems 1.3.7 (wget from website, extract, run setup.rb).
