Rails Server immediately exists start up - ruby-on-rails

Hi I'm new to Rails and have absolutely no idea why rails server won't work. I have no doubt the answer is in all this code below but I'm completely stuck. Any ideas?
Notice: server is listening on all interfaces (0.0.0.0). Consider using 127.0.0.1 (--binding option)
=> Ctrl-C to shutdown server

The config/secrets.yml file is invalid.
YAML is whitespace sensitive so make sure to check that there are no leading whitespaces. If you aren't sure if your YAML file is valid, try pasting it into this yaml validator http://yamllint.com/ to see if its valid.

I solved my problem restoring the last version of Gemfile

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:
davide#davidell:~/app/app-backend$ rails s

Now I got:

Something in your development.rb file wants to open the config/smtp.yml configuration file which is not present (see line 23). Probably this is due to a gem not configured properly. If you need further help, please add the development.rb to the question.

Anybody knows how to fix it?
Maybe i should to do something more then only bundle. I am just starting, sorry if its to easy.
You are missing configuration variable(s) and the pusher initializer cannot read the url, because its missing an url. You see it this line from your backtrace:
from /Users/abdullahatkaev/the247clinic/config/initializers/pusher.rb:1:in `<top (required)>'
Check this file to see what you need exactly. It depends on your project how you can set the url. Either through rails or something like dotenv.

Did you added devise in routes.rb file? If you use devise for users, then you should have this line in your routes.rb

Learn Ruby on Rails book: email configuration using TextEdit

I was on page 147 (epub) of Kehoe's Learn Ruby on Rails book and copied this code to config/environments/development.rb:
config.assets.debug = true
config.action_mailer.smtp_settings = {
address: "smtp.gmail.com",
port: 587,
domain: Rails.application.secrets.domain_name,
authentication: "plain",
enable_starttls_auto: true,
user_name: Rails.application.secrets.email_provider_username,
password: Rails.application.secrets.email_provider_password
}
However, after that and trying to run server I get this:
Boruckis-MacBook-Air:learn-rails szymonborucki$ rails s

I followed the tutorial to the letter, have Ruby 2.1.2 and Rails 4.1.4 installed. What should I do to get through it? I tried using the files from book's GitHub repo but result is the same. Here is the project:
https://github.com/SimonBo/learn-rails.git
The stack trace indicates the failure is in line 32 of config/environments/development.rb.
Try replacing domain: Rails.application.secrets.domain_name with:
domain: "example.com",
You'll need quotes and a comma.
If you get a subsequent failure on line 36 (as you report), replace:
user_name: "my_user_name",
password: "my_password"
You've got a problem with the config/secrets.yml file not set up properly. If your config/secrets.yml file sets the domain value with an environment variable, it's likely your environment variables are not set properly. If you have trouble setting Unix environment variables, you can add credentials directly to the config/secrets.yml file. If you do so, you should not check the file into Git until you’ve deleted the secrets from the file.
Tried it and got this:
$ rails s

=> Run `rails server -h` for more startup options
=> Notice: server is listening on all interfaces (0.0.0.0). Consider using 127.0.0.1 (--binding option)
