First update rubygems by following command:

That should solve it.
If not then try removing the following line from the rakefile
gem 'rspec', '~>2'

I am having a hard time figure out the first lesson on Test-First Ruby (Alex Chaffee), I am running "rake" test and am getting errors that I am not supposed to receive.
I already tried doing the gem update --system and removing spaces as suggested in previous posts. None of this solved the problem.
Bellow are my specs and errors received.
I will appreciate any help.

I've seen this before when --warnings was an option in the .rspec file.
Try removing the --warnings line from your .rspec or rspec_config file.
I'm learning to use Sinatra + Datamapper to build a lightweight webapp.
I ran gem install sqlite3 datamapper dm-sqlite-adapter and it seemed to have successfully installed...
I then tried to execute my .rb file which starts with:
require 'sinatra'
require 'datamapper'
and I got an error that it could not find the datamapper file.
C:/Ruby192/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:36:in `require': no such file to load -- datamapper (LoadError)
I also tried with require 'data_mapper' since there is conflicting information on the internetz as to the correct spelling of that gem, but same result.
I then listed all my installed gems (see below) and realilsed that there is no such gem as datamapper or data_mapper. I read so,ewhere that it is a meta-gem, I guess that means it doesn't actually install that one gem but rather all the gems starting with dm- ?
As a last resort I tried gem install data_mapper
and I got the ill fated:
C:\Users\Manu\Sinatra>gem install data_mapper
Building native extensions. This could take a while...
ERROR: Error installing data_mapper:
ERROR: Failed to build gem native extension.

I searched all over and just couldn't find anything to help me troubleshoot this, so hopefully there's someone roaming this forum with a magic wand and a pointy hat!
Many thanks

It seems the RubyInstaller Development Kit is missing:
http://rubyinstaller.org/add-ons/devkit/
The devkit installs a C-compiler (and some other stuff like make) to compile C-written parts.
Install it and try again to install the gem - perhaps with option --platform=ruby.
Details can be found at https://github.com/oneclick/rubyinstaller/wiki/Development-Kit
How do I get ruby-debug to run under XP so that I can step through my Watir test scripts.
I am unable to "require" ruby-debug on Windows XP. All of the solutions I have seen refer to a Unix-based system running Rails. Here is my system profile:

ruby-debug has been broken with recent ruby versions for a very long time. Try the debugger gem instead. I've no idea if it works on Windows though.
try this
gem install ruby-debug --pre
I am a new user to Ruby on Rails and am having an issue with: rake db:migrate.

Your bundle is complete! Use `bundle show [gemname]` to see where a bundled gem is installed.
Then, when I try and rake db:migrate, i get the following:
$ rake db:migrate
Could not find polyglot-0.3.2 in any of the sources
Run `bundle install` to install missing gems.
Anyone have any advice? Thanks.
I am on ruby 1.8.7 and rails 3.0.9
Check where it's installed:
gem list -d polyglot
Run bundle exec to make sure rake uses what's specified in your gemfile:
bundle exec rake db:migrate
Ya..apparently the polyglot gem is not included in your gem file.
Also try doing gem install polyglot...
Hope it helps !
bundle exec rake db:migrate might help too..
I am trying to install Gitorious in my local computer. However I get this error when I execute the console application:
/usr/lib/ruby/gems/1.9.1/gems/bundler-1.0.15/lib/bundler/rubygems_integration.rb:194:in
block in stub_source_index170':
undefined methodskip_during' for
Bundler::RubygemsIntegration::Deprecate:Class
(NoMethodError)
The ruby code that is executing in /usr/lib/ruby/gems/1.9.1/gems/bundler-1.0.15/lib/bundler/rubygems_integration.rb is:
def stub_source_index170(specs)
Gem::SourceIndex.send(:define_method, :initialize) do |*args|
#gems = {}
# You're looking at this thinking: Oh! This is how I make those
# rubygems deprecations go away!
#
# You'd be correct BUT using of this method in production code
# must be approved by the rubygems team itself!
#
# This is your warning. If you use this and don't have approval
# we can't protect you.
#
Deprecate.skip_during do
self.spec_dirs = *args
add_specs(*specs)
end
end
end
I guess the error occurs because the deprecate module is not loaded or something like that... I don't know ruby... but how can I try to correct it?

Newer versions of Rubygems are deprecating some old internal methods. You can downgrade Rubygems with gem update --system 1.x.y (e.g. 1.5.2) to see if that solves your problem.
Deprecate was namespaced to Gem::Deprecate. You can temporary patch it:
Gem::Deprecate.skip_during do
self.spec_dirs = *args
add_specs(*specs)
end
