Its my first rails program and I was following a rails tutorial which changed the gemfile but it hasn't worked, I guess I haven't installed something, I'm running gems 2.0.3 and rails 4.0.0 and with ruby I get this:
$ ruby -v
ruby 2.0.0p247 (2013-06-27) [i386-mingw32]
From here
download the required executable and the dll from http://www.sqlite.org/download.html extract to your ruby's bin (c:\Ruby200\bin)

Any suggestions? It has been bugging me whole day
The issue is that Rails 4.2.0beta and above have a dependency on the pty gem and it is unable to find it.
`require': cannot load such file -- pty (LoadError)
This is due to the fact that this gem is not yet available on Windows. For a temporary fix you can remove the web-console gem from your Gemfile and run bundle install after removing that gem.
I have installed a fresh install of Ruby / Rails on an clean Windows 8 install and amy getting errors when trying to start the WEBrick server. Have searched for an answer but cant find one.

Any help greatly appreciated
You need to use bundler to install the gem first.
Either do:
gem install mysql2
or
cd /my/rails/project && bundle install
note: the mysql2 gem is a [expletive] to install... best of luck

rm -rf ./vendor/bundle

Try updating Ruby and Rails with RVM - RVM is a command-line tool which allows you to easily install, manage, and work with multiple ruby environments from interpreters to sets of gems.

In Rails 3.2.12, when I run rails s it throws
/usr/local/share/gems/gems/activesupport-3.2.12/lib/active_support/dependencies.rb:251:in `require': cannot load such file -- bigdecimal/util (LoadError)
I even added gem 'bigdecimal' to Gemfile but still I am getting the same error, any pointers?
I had this issue with Rails 5.0.2 on a brand new Rails-generated application. The problem was that bigdecimal was not being loaded from my updated gemset but from the ruby-2.3.0 default gemset. This was resolved by adding gem 'bigdecimal' to my Gemfile.

I have same issue it seems.
I found this one, which might be relevant -- Difficulty with activesupport when attempting to deploy -- I've tried it but it did not worked for me. In my case 1.8 gems/tools got mingled with 1.9 so I've done more serious cleanup.
Check if you have multiple ruby installs by running which -a ruby and which -a rake and which -a rails. Tidy things up, so that you're using single ruby/bundler/rails combo. I've removed ruby 1.8 completely and left only 1.9 ruby on my system. Then I have cleaned all the gems in the system, and re-run the bundler. I am still missing something, because rake and rails continue to complain about bigdecimal/util
