No había tocado mi código en una semana, pero cuando lo empaqueté, luego intenté ejecutar mi servidor web, ahora obtengo los siguientes errores, que me están dejando muerto en el agua. La inclusión de la gema encriptable del dispositivo como se sugiere en la salida del error no resuelve el problema y sigue causando los mismos errores. Cualquier ayuda es muy apreciada.

[DEVISE] Devise.apply_schema is deprecated and has no effect. Please remove it.


[DEVISE] To select a encryption which isn't bcrypt, you should use devise-encryp
table gem.


[DEVISE] Devise.use_salt_as_remember_token is deprecated and has no effect. Plea
se remove it.

[DEVISE] You're trying to include :encryptable in your model but it is not bundl

to proceed.
