El archivo newrelic.yml en cuestión (de la sección de Cedro de this guide):

Answer 1

Su mensaje de error indica que <%= ENV["RAILS_ENV"] %> viene con las manos vacías entonces la primera línea de su YAML es solo un punto y eso no es muy útil.

supongo que está utilizando los carriles 3 y ENV['RAILS_ENV'] ya no está disponible (nota: Yo sé que no es de alrededor de 3.1 pero no estoy seguro de aproximadamente 3,0). Trate de usar esto:

<%= Rails.env %>: 

lugar, Rails.env debería estar disponible en todas las versiones rieles que es muy probable que esté utilizando. Y si eso no funciona, puede intentar ir directamente a:

production: 

ya que es probable que haya su entorno Heroku de todos modos.
