Bundler:GemNotFound error even though gem is locally installed - ruby-on-rails-4

In my application, I am using a cron job to execute a simple model method.
A few gems were required for this task.
I installed a gem by including it in the gemfile and running the command
bundle install
Now when I run the server, I get the following error:
/home/aditya9509/.rvm/gems/ruby-1.9.3-p551/gems/bundler-1.10.5/lib/bundler/spec_set.rb:92:in `block in materialize': Could not find mime-types-data-3.2016.0221 in any of the sources (Bundler::GemNotFound)

It says that the bundler was not able to locate mime-types-data-3.2016.0221 gem in any of the sources. To check, I ran the following command which gives a list of locally installed gems related to mime:
gem list | grep "mime"
This gave the following output:
mime-types (3.0, 2.99, 2.6.2)
mime-types-data (3.2016.0221)
Clearly the mime-types-data-3.2016.0221 is installed locally but bundler is not able to find it. Is there any fix to this. Below is my Gemfile:
source 'https://rubygems.org'

I am not sure as to what more information would be appropriate so let me know, I will update my question as needed.
Thanks!

Does the issue persist when running the server with bundle exec rails s?

error with puma in local server

I recently added puma to my app for better performance on heroku. my app works well in production (live) environment but I am getting and error in my local environment..

(Not a fix) by commenting line 1 of config/puma.rb, I was able to run puma in development.
or
workers Integer(ENV['WEB_CONCURRENCY'] || 0) also works
Not positive this will solve your problem. I usually run the app locally using foreman. The puma documentation for rails suggests starting your local server like this:
rails s Puma
For what it's worth.

No exception received from Rake task with Airbrake rails integration

Since version 5 Airbrake and its Rails integration offers automatic exception reporting in any Rake tasks.
However I've not received rake exception on my errbit server.
I've made the following test :
Create a fresh rails 4.1 application.
Include airbrake gem.
Create Airbrake initializer (used an errbit configuration).
Add a rake task which raises an exception.
Gemfile
source 'https://rubygems.org'
gem 'rails', '4.1.6'
gem 'sqlite3'
gem 'sass-rails', '~> 4.0.3'
gem 'uglifier', '>= 1.3.0'
gem 'coffee-rails', '~> 4.0.0'
gem 'jquery-rails'
gem 'turbolinks'
gem 'jbuilder', '~> 2.0'
gem 'sdoc', '~> 0.4.0', group: :doc
gem 'spring', group: :development
gem 'airbrake', '5.0.5'
initializers/airbrake.rb
Airbrake.configure do |config|
config.environment = Rails.env
config.host = 'https://xxxxxxxxxx.herokuapp.com/'
config.project_id = true
config.project_key = 'xxxxxxxxxxx'
config.ignore_environments = []
end
lib/rake/raise.rake
namespace :raise do
desc 'raise error'
task error: :environment do
1 / 0
end
end
I tried to execute the rake task rake raise:error and got the following backtrace:
rake aborted!
ZeroDivisionError: divided by 0
/Users/Yann/code/airbraker/lib/tasks/raise.rake:4:in `/'
/Users/Yann/code/airbraker/lib/tasks/raise.rake:4:in `block (2 levels) in <top (required)>'
/Users/Yann/.gem/ruby/2.2.2/gems/airbrake-5.0.5/lib/airbrake/rake/task_ext.rb:19:in `execute'
Tasks: TOP => raise:error
(See full trace by running task with --trace)
And never received any exception on my errbit server.
Note: execute rake airbrake:test sends an exception to my errbit server, I assume my configuration is correct.
Am I missing something ?
This is a minor bug. The problem is that Airbrake tries to be asynchronous and sometimes it doesn't work as expected. In this particular case the Ruby process quits before Airbrake sends your exception.
I've submitted a patch, which should fix this issue: https://github.com/airbrake/airbrake/pull/513

Could not find ruby-oci8, when deploying Rails application using Bundler

Not sure how to go about debugging this error. Deployment of this Rails application is successful on the development server but I get bundle stdout: Could not find ruby-oci8-2.2.0 in any of the sources (error) when deploying to the production server.
Is the error message saying that it can't find ruby-oci8 in the gemset? Any ideas on how I might go about debugging why the deployment isn't working on the production server?

It would sound like you have the Oracle Ruby gem in a development block. It would help if you posted your Gemfile.
I reverted the ruby-oci8 gem back to version 2.1.7 in the Gemfile instead of using the latest version of 2.2.0. And the deployment (bundle install) through Capistrano worked. On the Ubuntu servers I am using Oracle Instant Client and SDK version 11.2.0.3.0
After the successful deployment, I looked on the production server at the installed gems, the ruby-oci8 gem had a datestamp of this past February (when it was last installed) so I am curious if the ruby-oci8 had not previously existed and needed to be installed if the "bundle install" would work ...

Prawn in a Ruby on Rails app, failing on production

I am stuck on an issue with running prawn in production.
I have followed the Railscast (revised http://railscasts.com/episodes/153-pdfs-with-prawn-revised?view=asciicast) pretty much to the letter. It works great in my development environment (Mac OS X 10.9.1) but causes unicorn to falter on my server. My production server is (Redhat => Red Hat Enterprise Linux Server release 6.4 (Santiago)). I have the gem installed via Gemfile.
Gemfile:
gem 'prawn'
gem 'prawn-qrcode'
Controller: (show action)
def show
##classroom = Classroom.find(params[:id])
#classroom = find_classroom
#page_title = #classroom.location.name
#classroom_alt = #classroom.location.name + " - " + #classroom.room_number
#building = find_building(#classroom.location_id)
#owner = Owner.find(#classroom.owner_id)
#room_schedule_contact = RoomScheduleContact.find_by rmrecnbr:(#classroom.rmrecnbr)
#building_image = #building.picture.url(:medium).to_s
#building_sign_image = #building.building_sign.url(:thumb).to_s
#search = Classroom.search(params[:search])
##classroom_herprod = Building.find(params[:location_id]).building_short_code
respond_to do |format|
format.html # show.html.erb
format.png { render :qrcode => "http://rooms.lsa.umich.edu/classrooms/#{#classroom.facility_code_heprod}", :level => :l, :unit => 8 }
format.pdf do
pdf = ClassroomPdf.new(#classroom)
send_data pdf.render, type: "application/pdf",
disposition: "inline"
end
end
end
I have a pdfs directory with a classroom_pdf.rb file that includes the following.
class ClassroomPdf < Prawn::Document
def initialize(classroom)
super(top_margin: 70)
text "This is a pdf"
end
end
(This is stripped down from what I had, but it is the most basic version that works on my dev system and fails on production).
I am running the following

Active admin in Rails 4 throws error "Invalid option key"

Rails 4 app working just fine until Active Admin is included (from this thread) in the gemfile.
My Gemfile:
gem 'rails', '4.0.0'
gem 'rails_12factor', group: :production
gem 'pg'
gem 'sass-rails', '~> 4.0.0.rc1'
gem 'uglifier', '>= 1.3.0'
gem 'coffee-rails', '~> 4.0.0'
gem 'activeadmin', github: 'gregbell/active_admin'
gem 'protected_attributes'
gem 'rails-observers'
gem 'actionpack-page_caching'
gem 'actionpack-action_caching'
gem 'jquery-rails'
gem 'turbolinks'
gem 'jbuilder', '~> 1.2'
group :doc do
gem 'sdoc', require: false
end
The error is thrown while attempting to start the rails server after a clean bundle install.
/var/lib/gems/1.9.1/gems/actionpack-4.0.0/lib/action_controller/railtie.rb:55:in `block (3 levels) in <class:Railtie>': Invalid option key: page_cache_directory= (RuntimeError)
Any help is greatly appreciated!
