Error al implementar con Capistrano

Question

Estaba siguiendo el Railscast en Despliegue a un VPS y todo funciona sin problemas hasta que intento ejecutar cap deploy. Parece que falla al intentar encontrar un directorio. Aquí está el mensaje de error:

* executing `deploy'

* executing `deploy:check_revision'

He pasado siglos en esto y parece que no puedo encontrar dónde me estoy equivocando.

Answer 1

¿Has ejecutado cap deploy:setup y cap deploy:check? Estos deberían resaltar una gran cantidad de problemas comunes.

El error que causa la falla anterior, sin embargo, parece un problema de permisos.

cp: cannot create directory `/home/deployer/apps/dropwall_rails/releases/20120513204913': No such file or directory 

Asegúrese de que la carpeta exista y de que el usuario de implementación tenga los permisos correctos para manipularla.

Answer 2

El problema de los privilegios puede ser causado por el comportamiento de Capistrano use_sudo por defecto.

Esto puede ser anulado por los siguientes parámetros de configuración: conjunto: use_sudo, falsa

Lo extraño es que si este parámetro no se establece en false, Capistrano utilizará para algunos comandos sudo y no utilizar para otros. Me parece como un insecto.
