I'm a fairly new dev to ruby and especially rails, but I do have some perl and php experience. Anyway, I'm trying to get rails version 3 configured on Ubuntu 10.10 using the latest ruby package: v1.9.2-p136. It isn't going too well, though better than p0: at least they included the yaml.rb and friends, so that I'm not spending my time cobbling them together. However, I'm still having a problem with the YAML package, which manifests itself whenever I try to install or configure any gem or package. I installed rails through synaptic already; this was just for showcasing the problem.
gem i rails
ERROR: Loading command: install (NameError)
uninitialized constant Syck::DefaultResolver
ERROR: While executing gem ... (NameError)
uninitialized constant Gem::Commands::InstallCommand
This actually showed up when I tried to install redmine with synaptic: it now says every synaptic installation ends in failure, all because of:
rake aborted!
uninitialized constant Syck::DefaultResolver
