Capistrano 3 Fehler mit Schienen 5

Question

Ich habe eine Schiene 5 app (nach dem Upgrade), die folgenden Capistrano 3.0 Plugins verwendet:

# Deployments 
    gem 'capistrano', '~> 3.6' 
    gem 'capistrano-rails', '~> 1.1' 
    gem 'capistrano-bundler', '~> 1.1.2' 
    gem 'capistrano-rbenv', '~> 2.0' 
    gem 'capistrano-safe-deploy-to', '~> 1.1.1' 
    gem 'capistrano-secrets-yml', '~> 1.0.0' 
    gem 'capistrano-faster-assets', '~> 1.0' 
    gem 'capistrano-ssh-doctor', '~> 1.0' 
    gem 'capistrano-postgresql', '~> 4.1.0' 
    gem 'capistrano-delayed-job', '~> 1.0' 
    gem 'capistrano-unicorn-nginx', '~> 3.1.0' 
    # gem 'capistrano-memcached', '~> 1.0' 
    # gem 'capistrano-maintenance', github: "capistrano/maintenance", require: false 

Im Moment scheint es, dass Capistrano-rbenv 5 mit Schienen bummed.

Hat noch jemand dieses Problem gesehen?

Answer 1

Es war eine sehr einfache Lösung:

Schloss deploy.rb auf Version '3.6' und set :rbenv_ruby, '2.3.1' etwa so:

# config valid only for Capistrano 3.6 
lock '3.6' 

set :application, 'yourAppName' 
set :repo_url, 'your gitlab url' 
set :deploy_to, '/var/www/yourAppName' # Default deploy_to directory is /var/www/my_app 

set :pty, true # Default value for :pty is false 

# CONFIGURATION: RBENV 
# ================== 
set :rbenv_type, :user # or :system, depends on your rbenv setup 
set :rbenv_ruby, '2.3.1' 
set :rbenv_prefix, "RBENV_ROOT=#{fetch(:rbenv_path)} RBENV_VERSION=#{fetch(:rbenv_ruby)} #{fetch(:rbenv_path)}/bin/rbenv exec" 
set :rbenv_map_bins, %w(rake gem bundle ruby rails) 
set :rbenv_roles, :all # default value
