mysql,ruby,windows-7,gem,rubygems

The 'mysql' and 'mysql2' packages/extensions/gems don't work with the x64 bit version of Ruby on Windows 7 (or any 64 bit version of Windows). You need to install the x86 (32) bit version of Ruby for them to work. So I repeated step 3 in my question, and installed...

gem install fails with “Could not find a valid gem 'yaml'”

ruby,gem,rubygems,ubuntu-14.04

Rails doesn't load actionform gem from Gemfile

ruby-on-rails,gem,rubygems,bundler

The problem is a mismatch between the gem name and the file inside the gem.

You can tell Bundler the right file name with this syntax: gem 'actionform', :github => 'rails/actionform',...

How do I send simple mails from a gem, without requiring ActionMailer, but using its configuration if present?

That works exactly as I needed it to...
