Answer 1

I think your machine has multiple spring gem version. I would like to remove spring 1.3.3.

$ gem uninstall spring

It shows all spring gems on your machine

I had similar issue, it solved the issue

Answer 2

change in your application Gemfile

gem 'spring'

to

gem 'spring', "~>1.3.3"

and

bundle install
bundle update

it work for me!
