Input problems on RubyMine

Hi everyone, I'm new using RubyMine. Recently I made this simple program (add two numbers giving by the user). But when I try to compile it doesn't add those numbers, only receives number indefinitely. The first image is from the program. The second one is the result of compiling the program

Someone can help me with this? 

 EDIT ONE: When I run this program on the console (ruby *name.rb*) it works perfectly. I'm using Ruby 2.5.3
