Carga de Rspec/Capybara en curso, circular requiere considerado dañino

Question

No estoy seguro si esto es un problema de Capibara, pero acabo de hacer una nueva instalación de Rails (4.1.1) y Rspec Rails (3.0.1) y me gustaría usar Capybara (2.3.0), pero nunca lo he usado. Estoy corriendo en problemas. Creé una "especificación" en especificaciones / características y la especificación en sí se ejecuta y pasa como se esperaba, pero recibo las siguientes "advertencias" cuando se ejecuta rspec. ¿Algunas ideas? ¿Solo necesito desactivar las advertencias en el nivel de rubí o algo así?

Answer 1

Eliminar - --warnings de .rspec . El generador en rspec 3.0.0 incluyó esta configuración, pero nos dimos cuenta de que fue un error, aunque es bueno alentar a los usuarios a escribir código de advertencia, es confuso para los usuarios obtener estas advertencias sin estar seguros de por qué.
