Trying to get this to work, but I'm having trouble. I'm following the instructions at:
https://www.railstutorial.org/book/beginning#cha-beginning
I get to 1.3.2 and I type:
rails server -b $IP -p $PORT
Which results in this error instead of WEBrick running:

This seems to only happen when you replace the Gemfile code with the code specified to get the explicit version of Ruby gems (the code below).
source 'https://rubygems.org'
gem 'rails', '4.2.0'
gem 'sass-rails', '5.0.1'
gem 'uglifier', '2.5.3'
gem 'coffee-rails', '4.1.0'
gem 'jquery-rails', '4.0.3'
gem 'turbolinks', '2.3.0'
gem 'jbuilder', '2.2.3'
gem 'sdoc', '0.4.0', group: :doc
group :development, :test do
gem 'sqlite3', '1.3.9'
gem 'byebug', '3.4.0'
gem 'web-console', '2.0.0.beta3'
gem 'spring', '1.1.3'
end
Looks like the tutorial has just recently fallen out of date. If you update your gemfile from
gem 'sass-rails', '5.0.1'
to
gem 'sass-rails', '5.0.2'
then bundle install again and launch the server, it should work just fine.
(If you prefer, you can also run a workaround by adding
gem 'sass', '3.4.13'
before your existing, non-updated line:
gem 'sass-rails', '5.0.1'
in your gemfile, and doing a bundle install and launching the server. I don't know why you'd need to, though.)

This question already has an answer here:
Rails application using Postgres adapter can't activate pg
(1 answer)
Closed 5 years ago.
I've been doing the Rails tutorial found here and have been successful up to the point of having to migrate the Comments migration using $ rails db:migrate. Prior to this point, I've been able to generate the Article model and migrate the Articles create migration with no issues. In between these two migrations, nothing has changed in my Gemfile, so I'm not sure what it is Bundler is having an issue with.
Here are the errors, followed by the full command-line output, along with my Gemfile and schema.rb:
Gem::LoadError: can't activate pg (~> 0.18), already activated pg-1.0.0.
Gem::LoadError: Specified 'postgresql' for database adapter, but the gem is not loaded. Add `gem 'pg'` to your Gemfile (and ensure its version is at the minimum required by ActiveRecord).

looks like pg 1.0 is not compatible with rails 5.1.4 at the moment.
gem 'pg', '~> 0.18'
0.18 worked for me.
Turns out the postgres gem version 1.0.0 is not compatible with Rails 5.1.4. When I changed the postgres gem version to '~> 0.18', everything worked fine:
Changed from:
gem 'pg' # Defaults to latest version 1.0.0 (not compatible with Rails 5.1.4).
Changed to:
gem 'pg', '~> 0.18'

Anything else I could try?
If you're working with Rails 5, do not include the gem rails-api (which is already included in Rails 5).
After I upgraded my shoulda gem to 3.4.0, my tests would no longer run.
Context:
Ruby 1.9.3-p392
Rails 3.2.12
Rspec 2.13.0 Mac
OS X 10.8.3
When I set up my Gemfile and run bundle exec rspec spec I get the following errors:
#Gemfile #1
group :test do
gem 'rspec-rails', '2.13.0'
gem 'shoulda', '3.4.0'
end

These are the only Gemfile versions that work, but they don't seem to be the correct setup:
#Gemfile #4
group :test do
gem 'factory_girl_rails', '4.2.1'
gem 'rspec', '2.13.0'
gem 'rspec-rails', '2.13.0'
gem 'shoulda-matchers', '1.5.0'
end

Any help would be highly appreciated.
This is a bug. Details can be found in a Google Group discussion named dirname: can't convert nil to string problem.
You can fix this by upgrading cucumber-rails to a recent version. Just edit your Gemfile to show this:
