预编译时Rails生产bootstrap-sass错误

Question

Everything is working great with my rails app in development environment. But when I try it in production mode I get this error when I'm doing some precompile :

RAILS_ENV=production rake assets:precompile --trace
** Invoke assets:precompile (first_time)
** Invoke assets:environment (first_time)
** Execute assets:environment
** Invoke environment (first_time)
** Execute environment
rake aborted!
NoMethodError: undefined method `<<' for true:TrueClass
/home/xxxxx/.rvm/gems/ruby-2.1.5/gems/bootstrap-sass-3.3.4.1/lib/bootstrap-sass/engine.rb:8:in `block in <class:Engine>'
/home/xxxxx/.rvm/gems/ruby-2.1.5/gems/railties-4.1.6/lib/rails/initializable.rb:30:in `instance_exec'
/home/xxxxx/.rvm/gems/ruby-2.1.5/gems/railties-4.1.6/lib/rails/initializable.rb:30:in `run'
/home/xxxxx/.rvm/gems/ruby-2.1.5/gems/railties-4.1.6/lib/rails/initializable.rb:55:in `block in run_initializers'

I already tried multiples solutions found but none works so far.

I tried to add config.assets.initialize_on_precompile = false into config/application.rb without success...

As @infused pointed out, there was a config.assets.precompile = true somewhere in my code that was create this error. Removing it resolved this issue !
