It seems the command is trying to load multiple rails dependencies while creating the application.

You can resolve this by

$ gem update rails

Or

$ gem update --system

You have multiple version of activesupport. You should remove one of them: 

$ gem list | grep activesupport

Activesupport (5.1.1, 5.0.4, 5.0.3, 5.0.2, 5.0.0.1, 4.2.6, 4.2.5, 4.2.4, 4.2.1, 4.1.6)

then

$ gem uninstall activesupport -v 5.1.1

Successfully uninstalled activesupport-5.1.1

In your case, I guess it is activesupport-5.0.6
