hi @spuder. I checked on my computer and can confirm this problem. I tried to track which dependency is causing problem. I managed to correctly run bundle install with those changes in Gemfile

gem 'json', '~> 2.1'
gem 'padrino', '~> 0.14.2'

The problem right now is the dm-types gem.

/Users/karolkozakowski/.rvm/gems/ruby-2.3.0/gems/bundler-1.16.1/lib/bundler/runtime.rb:84:in `rescue in block (2 levels) in require': There was an error while trying to load the gem 'dm-types'. (Bundler::GemRequireError)

Last release of dm-types was on: August 02, 2012 so it is possible that something is not working with newer Ruby versions.

I managed to make it run but after loading / I now have:

DEBUG -  TEMPLATE (0.0043s) /user/signin.html
EBUG -  TEMPLATE (0.0003s) /layouts/user.html
2018-02-08 08:28:40 - NoMethodError - undefined method `gsub' for {}:Hash:

I will try to debug it more at home but you can try to update gems and see if it will help.

rm Gemfile.lock
bundle install

fixed the issue for me
