Ruby on Rails Thursday, January 19, 2017

In my application whenever I try to start rails server following warning pop-up

warning: constant ::Fixnum is deprecated
warning: constant ::Bignum is deprecated
=> Booting Puma
=> Rails 5.0.1 application starting in development on http://localhost:3000
=> Run `rails server -h` for more startup options
warning: constant ::Fixnum is deprecated
Puma starting in single mode...
* Version 3.6.2 (ruby 2.4.0-p0), codename: Sleepy Sunday Serenity
* Min threads: 5, max threads: 5
* Environment: development
* Listening on tcp://localhost:3000
Use Ctrl-C to stop

Is it something from backend or I'm missing something to install on my
machine which produce this.
