undefined method 'inline' for ImageScience:Class (NoMethodError) - ruby-on-rails

I am migrating a Rails 2.1.2 application to Rails 2.3.11
To make my life easier i used bundler but I get the following error when starting my server:
/Library/Ruby/Gems/1.8/gems/image_science-1.2.1/lib/image_science.rb:90: undefined method `inline' for ImageScience:Class (NoMethodError)

It is kind of strange because i got it working without bundler. I think i am missing a gem dependency.

Actually, it looks like you probably want this answer: ImageScience breaks on update to Rails 3

I'm new to rails so I don't know what to look for. In the past I'd go to the directory in question (/usr/lib/ruby/gems/1.9.1/gems/) and make sure everything was readable by non-root users and groups. This hasn't worked this time around.
I also noticed that my Gemfile mentioned sass-rails 3.2.3 while the installed version is 3.2.6. I modified the Gemfile to reflect this but still get the errors.
My Gemfile:
source 'https://rubygems.org'
gem 'rails', '3.2.12'
# Bundle edge Rails instead:
# gem 'rails', :git => 'git://github.com/rails/rails.git'
gem 'sqlite3'
# Gems used only for assets and not required
# in production environments by default.
group :assets do
gem 'sass-rails', '~> 3.2.6'
gem 'coffee-rails', '~> 3.2.1'
# See https://github.com/sstephenson/execjs#readme for more supported runtimes
# gem 'therubyracer', :platforms => :ruby
gem 'uglifier', '>= 1.0.3'
end
gem 'jquery-rails'
# To use ActiveModel has_secure_password
# gem 'bcrypt-ruby', '~> 3.0.0'
# To use Jbuilder templates for JSON
# gem 'jbuilder'
# Use unicorn as the app server
# gem 'unicorn'
# Deploy with Capistrano
# gem 'capistrano'
# To use debugger
# gem 'debugger'
The log directory under the application directory is empty so there is nothing to report from there.
The server starts fine when run with sudo. However, as I have this in my own /home directory that shouldn't be the case.

Put sass-rails above rails in your gemfile.
The sass-rails gem is trying to setup the logger and cannot find the Sass::Rails::Logger class.
https://github.com/rails/sass-rails/blob/3-2-stable/lib/sass/rails/railtie.rb#L23
This is probably because you are calling sass before it has time to setup and autoload.

Gem Dependency Problems With Legacy App

I suspect I may need to downgrade my version of ruby-gems but I'm at a loss as to how to determine and appropriate version.
These are my local gems:
*** LOCAL GEMS ***

For Rails 2.2 gem version 1.4.2 works I guess. Try downgrading to 1.4.2
sudo gem update --system 1.4.2 or rvm install rubygems 1.4.2

Try this
gem install rubygems-update -v='1.4.2'
gem uninstall rubygems-update -v='1.5.0'
update_rubygems

Your bundle is complete! Use `bundle show [gemname]` to see where a bundled gem is installed.

I had the identical issue. In my case I had a model class called Diff (defined in diff.rb) which led to the issue. I've renamed my class/module and all is well now. I'm somewhat disappointed that this sort of namespace collision could occur.
Other users have also encountered issues with collisions originating from other gems (eg: https://github.com/sunaku/tork/issues/3). If I were troubleshooting the issue, I'd go to your gem directory (use bundle show for any one of your gems to find where they live) and run
find . -name diff.rb
That should tell you all of the libraries that contain a diff.rb file. I'd be looking for one of the more obscure/less actively maintained gems to be the culprit. You'll likely need to find an alternative gem (or contribute a fix the offending gem!) to fix the issue.

Where does the problem come from?
Thank you very much for your help!

Your version of the DeviseInvitable is too new for Rails 2.3.
DeviseInvitable currently only support Rails 3, if you want to use it with Rails 2.3 you must install version 0.2.3
As is Devise 1.1
Support for Rails 2.3.x can be found by installing Devise 1.0.x from the v1.0 branch.
Run
gem uninstall devise devise_invitable
gem install devise --version 1.0.10
gem install devise_invitable --version 0.2.3

Solutions above did not work. Solution for me was to require rubyzip version less than 1.0 i.e.
gem 'rubyzip', '~> 0.9.9'
It seems the latest selenium-webdriver now requires rubyzip < 1.0.0 so this shouldn't be a problem anymore but posting in case of it happens to someone else.

I found my answer, the problem is about a gem named "rubyzip" that missed in my gem list.

I don't quite understand the source of this error. It seems like a missing dependency of Active Support. Anyway, I was able to get past the error by explicitly adding the gem and requiring it in my Gemfile:
gem 'rubyzip', :require => 'zip/zip'

This is an interface-breaking change when moving rubyzip from 0.9.9 to 1.0.0. The issue is described here.
As a short-cut back to working, you may be interested in the zip-zip gem.

I had this issue as well when trying to run cucumber after updating selenium-webdriver.
The newest version of selenium now requires rubyzip ~> 1.0, which you will need to put in your Gemfile and explicitly require:
gem 'rubyzip', require: 'zip'

When using phusion passenger it seems that the gems have to be installed globally.
When I ran 'gem install ' from within my project directory it showed the gem as being installed but still resulted in the 'no such file to load...' error.
On a hunch I went outside the project directory and did a 'gem list' and the gem installed above was not listed, so I did 'gem install ' outside of the project directory and the error was fixed.
Please not that this was Phusion Passenger implementation not just rails.
