ruby - `<module:Templates>': uninitialized constant Tilt::CompileSite (NameError) using Sinatra / Unicorn

Question

I'm new in the Ruby world. I created my first app using Sinatra, and I'm having some trouble on my production server.

When I run unicorn -c randmovie_unicorn.rb on my local machine, it works just fine. But in production, I get this error:

<module:Templates>': uninitialized constant Tilt::CompileSite (NameError)

In my randmovie_unicorn.rb file:

preload_app true  
working_directory "./"  
listen 8006  
worker_processes 2  
timeout 30

I'm not using HAML or anything similar.

Could somebody help me with that? Thanks!

I think it's a bug in tilt 2.0.0 or in sinatra. Specify tilt version in your Gemfile:

gem 'tilt', '~> 1.4.1'
