Question

I’ve deployed my app to a remote machine using Capistrano and Passenger. The project is on GitHub, and I want to work on some bug fixes on my local machine. I’ve synced up everything, and branched to a new ‘dev’ branch on my local machine. When I try the simple rails server command I had been using while developing, I get errors relating to the gems bundled in my Gemfile, e.g. `require': no such file to load -- nokogiri/nokogiri (LoadError). But when I run bundle show nokogiri, it’s present at /vendor/cache/ruby/1.9.1/gems/nokogiri-1.5.0.

Maybe this is just the wrong workflow entirely, but how do I get to a development mode on my local machine, so I can test changes before pushing them to the deployed app?

My Gemfile:

source 'http://rubygems.org'

gem 'rails', '3.0.10'

# Bundle edge Rails instead:
# gem 'rails', :git => 'git://github.com/rails/rails.git'

gem 'sqlite3'
# Use unicorn as the web server
# gem 'unicorn'

# Deploy with Capistrano
gem 'capistrano'

# To use debugger (ruby-debug for Ruby 1.8.7+, ruby-debug19 for Ruby 1.9.2+)
# gem 'ruby-debug'
# gem 'ruby-debug19', :require => 'ruby-debug'

# Bundle the extra gems:

gem 'nokogiri'
# gem 'sqlite3-ruby', :require => 'sqlite3'
gem 'nested_scaffold'
gem 'rest-client'
gem 'pony'
gem 'mail'
gem 'logger'
gem 'json'
gem 'gmail'


# Bundle gems for the local environment. Make sure to
# put test-only gems in this group so their generators
# and rake tasks are available in development mode:
# group :development, :test do
#   gem 'webrat'
# end

I suggest you delete .bundle directory (consider backing up whatever’s inside .bundle/config first) and run your bundle install command again. You can do cat .bundle/config to echo its contents to your terminal (STDOUT).

Make sure you have chosen the correct gemset by doing rvm gemdir and gem list to see all the gems in the current gemset.

Start your server with rails s -e development (s is short for server)
