I have the following Gemfile:
source "http://rubygems.org"
gem 'sinatra', '1.3.2'
gem 'json', '1.6.4'
And the following Sinatra application:
require 'sinatra'
require 'json'
get '/ze/api/session.json' do
content_type :json
{ :name => 'name' }
end
And when I make a basic request like this one:
curl localhost:4567/ze/api/session.json
I get this:

I am using Ruby 1.9.2 with RVM in a Lion Mac.
You're trying to return a hash from the route, but a hash isn't something you can return here.
Simply use
.to_json
to turn the hash into a json string which you can then return (you've required json, but aren't using it yet):
