If you have run "bundle install" to install bcrypt, just restart the rails server.

The error message is very clear that you either not installed bcrypt gem or the bcrypt gem is not successful.
Open your gem file and add the below line and run bundle install. Be sure to restart the server.
gem 'bcrypt-ruby', '3.1.1.rc1', :require => 'bcrypt'

Rails: Couldn't load the Unicode tables for UTF8Handler

I'm on a fresh Ubuntu 17.10 machine, Ruby 2.2.3 installed with RVM, and I'm trying to run a Rails 4.2 application.
After rails s command I get:

Error Using Any Rake Command with Rails

I ran rake db:migrate, and the migration worked. However, it gives me this error when i try to use any rake command.
/Library/Ruby/Gems/2.0.0/gems/devise-3.5.6/lib/devise/models.rb:80:in `map': undefined method `to_sym' for nil:NilClass (NoMethodError)
I'm not sure how to fix this, as rake db:rollback also causes the error.
EDIT
devise :database_authenticatable, :registerable,

You have to define a root route in your config/routes.rb file or at least one route.
Here is an exemple :
# At least a route (here for HelloController)
get '/hello' => 'hello#index'
# Or a root route
root 'hello#index'

But if i disable the config.cache_classes setting it to false, the error wont show up anymore.
But there is no way that im leaving cache_classes = false into production.
Can someone help me with this?
Many thanks
The AWS SDK was out of date.
Updating it solved the hole trouble :)
Thanks Deefour

Ruby gem devise error after generating model

I've been stuck on this problem since yesterday now, I've scoured the internet and it seems a lot of people have had this same error after running 'rails generate devise User'
I'm running what I believe to be the latest version of Devise (3.0.0.rc) and when I try to run 'rails server', I get the below error message. (I followed the insructions given by devise upon install)
I can't destroy the model, I can't migrate my db and I have to delete the whole project and start again every time.
Please help!
