I'm trying to install Rails 3.1.
It says to use 'gem install rails --pre' in the announcement blog post here:
http://weblog.rubyonrails.org/2011/5/22/rails-3-1-release-candidate
When I try
$ gem install rails --pre
I get the error:
ERROR: While executing gem ... (NameError) uninitialized constant Syck::Syck
What to do?

Use `gem install -v` You may already be familiar with gem install , but if you add the -v flag, you can specify the version of the gem to install. Using -v you can specify an exact version or use version comparators.
Go to your browser and open http://localhost:3000, you will see a basic Rails app running. You can also use the alias "s" to start the server: bin/rails s . The server can be run on a different port using the -p option. The default development environment can be changed using -e .
Regarding your specific problem: You may be seeing an error introduced by a faulty build of Rails 3.0.8.rc3 that got pushed as "rails --pre". See this issue in the Rails repository.
Instead of
gem install rails --pre
for the newest version, use
gem install rails -v ">=3.1.0rc"
or for 3.1.0.rc1 specifically:
gem install rails --version=3.1.0.rc1
See the guide referenced above for more advice.
