Rails & Amazon RDS: "production database is not configured" - amazon-ec2

I'm brand new to all things AWS, and trying to boot up my Rails app on Beanstalk. I'm following the recent tutorial, but I'm stuck getting my app connected to RDS. The passenger screen comes up with an error:
production database is not configured (ActiveRecord::AdapterNotSpecified)
My database.yml looks like:
production:
  adapter: mysql2
  encoding: utf8
  database: <%= ENV['RDS_DB_NAME'] %>
  username: <%= ENV['RDS_USERNAME'] %>
  password: <%= ENV['RDS_PASSWORD'] %>
  host: <%= ENV['RDS_HOSTNAME'] %>
  port: <%= ENV['RDS_PORT'] %>
I do have an RDS instance configured and running. I also ssh'ed into the EC2 instance, and verified that I can successfully connect to the RDS via RDS_USERNAME, RDS_HOSTNAME, etc.
Thinking that perhaps I needed to manually create my database in MySQL I used the MySQL client to do that, but I still get the same error.
So again on the EC2 instance I checked out my project manually and ran bundle exec rake db:migrate --trace to get a more complete picture of where it's failing:
** Invoke db:migrate (first_time)
** Invoke environment (first_time)
** Execute environment
** Invoke db:load_config (first_time)
** Execute db:load_config
rake aborted!
production database is not configured

Diaspora (Ruby) run Error, Maybe PATH Problem? "uninitialized constant TurboDevAssets (NameError)"

I try to migrate diaspora from a damaged debian 8 to another gentoo. I want to be able to can run diaspora before I deploy the web server. I crashes because of Ruby Errors, maybe kind of PATH errors.
When I run diaspora with script/server in production mode it crashes because the thing behind web.pid crashes. In the log eye_processes_stderr.log is:
bin/bundle:3:in `load': cannot load such file -- /usr/lib/ruby/bin/bundle (LoadError)
from bin/bundle:3:in `<main>'
In development mode I can not execute correctly (I tried it to get better error message reporting):
RAILS_ENV=development bin/rake db:migrate RAILS_ENV=development
bin/rake assets:precompile
because of the stdout and stderr of script/server I run: bin/bundle exec unicorn -c config/unicorn.rb
In production mode it returns:
that I shall look into stderr
and in the log there is nothing helpful, in:
tail log/eye_processes_stderr.log:
bin/bundle:3:in `load': cannot load such file -- /usr/lib/ruby/bin/bundle (LoadError)
from bin/bundle:3:in `<main>' bin/bundle:3:in `load': cannot load such file -- /usr/lib/ruby/bin/bundle (LoadError)
from bin/bundle:3:in `<main>'
But in development mode it returns:

It shall run as it did with every working diaspora as it has worked on debian 8 when I used rvm in the home directory. (as I also tried that on the Gentoo machine)

Can't start rails server - "Failed to watch" error - Bash - Ubuntu - Windows 10

The problem is that the server will not start.
I have set up the following:
Windows 10 build 1607 (Anniversary edition)
Windows subsystem for Linux
GNU bash, version 4.3.11(1)-release (x86_64-pc-linux-gnu)
Ubuntu 14.04.5 LTS \n \l
Rails ver 5.0.0.1
Ruby ver 2.3.1 (using - rbenv)
MySQL 5.5.53
I am very new to Linux and Ruby / Rails so please forgive me if I use incorrect terminology.
After a few days of installing, configuring and debugging, I was able to get everything working (Linux shell, rails, ruby mysql etc.).
I began a tutorial at Lynda called "Ruby on Rails 5 Essential Training" and was able to do the following:
Create a new rails project called Simple CMS
Create MySQL databases for development and test
Create users in MySQL
** When it came time to start the web server (Puma via the 'rails server' command) I received pages of errors as shown. I've searched every stackoverflow, google, Microsoft and GitHub result that had anything to do with "Failed to watch" and the above noted configuration. There were no solutions and the latest result stated that it was not possible to run the server because of the way Windows works.
Before scrapping my installation I wanted to ask here if anyone had run across this and/or had a solution.
Thank you very much in advance for any help and for taking the time to read this.
Mike
Here is the error including the command I used to initiate it:(Sorry its huge)

Found a solution in #jwsloan's comment on this Github issue:
When creating a new rails app, use --skip-listen to avoid problems with inotify, like so:
rails new myproject --skip-listen
That should allow the server to start - worked for me! :)

ruby - Error with installing bluecloth-2.2.0 gem in Win 7 , ruby 1.9.3

Was following steps described in https://stackoverflow.com/a/13544086/3206440 for resolving error with bluecloth-2.2.0 gem installation in windows 7. Encountered an error in step 4 given in the above link - any ideas?

If your using Hoe then be sure to disable some of the plugins. I'm not sure which ones are enabled by default but you could certainly try that first.
Homepage here
I would suggest starting out with the list of them like so:
Hoe.plugins.delete :newb
and then just comment them out as needed.
Please create .gemtest folder in root of project

Please help me.
Thanks ~!!
The error is coming from:
config/initializers/raven.rb
which looks like it has something to do with the sentry-raven gem, based on the stack trace lines right above that. You should check the documentation for that gem and make sure that any code in that initializer plus any environment variables are set appropriately for your production environment on heroku.
Check your config variables, particularly DATABASE_URL as shown here. Also verify you used the Heroku add-ons for Postgres, Mongo, Neo4J, or whatever you're using rather than connect anything yourself.

I'm totally noob in ruby; sorry for stupid question.
I just replicated your issue and can confirm it is a ruby version problem. Using 1.8.7-p375 your issue arises. Using Ruby version 1.9.3-p545 the command runs just fine. The project maintainer should specify a ruby version in their project, I will file a github issue for them to clarify this. Other answers have alluded to this; use your favorite method to upgrade your ruby, I suggest rbenv.
