rails console require cannot load such file readline

Question

I am new to Ruby on Rails, and I install ruby by source.

Ruby version is 2.3.0 and rails version is Rails 4.2.5.

I can't run rails c or rails console.

It giving me the following error:

EDIT

I try second solution in @Vasfed link, and it give me following error:

make: *** No rule to make target `/internal.h', needed by `readline.o'.  Stop.

Answer 1

Readline gem is required by your application but not specified in your Gemfile

Please add this to your gem file

gem 'rb-readline' 

Also reinstall

libreadline-dev
