Why I get undefined method `each'?

In application.rb I tried to read a YAML file:

config.before_configuration do
    env_file = File.join(Rails.root, 'config', 'local_env.yml')
    YAML.load(File.open(env_file)).each do |key, value|
    ENV[key.to_s] = value
        end if File.exists?(env_file)
    end

but, I get this error:

/var/www/config/application.rb:26:in `block in <class:Application>': undefined method `each' for #<String:0x00000007afb7f0> (NoMethodError)

Any idea?
