cap deploy + rbenv: bundle: command not found

问题

I am following https://gorails.com/deploy/ubuntu/16.04

I am running : "bundle exec cap production deploy" and getting the following error:

"gem list" shows : bundler (1.14.6) on both machines, as well as ruby 2.4.0 on both my production machine as well as the server. How to proceed?

I am posting my Capfile:

# Load DSL and set up stages
require "capistrano/setup"

# Include default deployment tasks
require "capistrano/deploy"

# Load the SCM plugin appropriate to your project:
#
# require "capistrano/scm/hg"
# install_plugin Capistrano::SCM::Hg
# or
# require "capistrano/scm/svn"
# install_plugin Capistrano::SCM::Svn
# or
require "capistrano/scm/git"
install_plugin Capistrano::SCM::Git

# If you are using rbenv add these lines:
require 'capistrano/rbenv'
set :rbenv_type, :user
set :rbenv_ruby, '2.3.1'

require 'capistrano/bundler'
require 'capistrano/rails'
require 'capistrano/passenger'

# Load custom tasks from `lib/capistrano/tasks` if you have any defined
Dir.glob("lib/capistrano/tasks/*.rake").each { |r| import r }

my deploy.rb:

# config valid only for current version of Capistrano
lock "3.8.1"

set :application, "deploy_test1"
set :repo_url, "git@bitbucket.org:confidentialname/deploy_test1.git"

set :deploy_to, '/home/deploy/deploy_test1'

#append :linked_files, "config/database.yml", "config/secrets.yml"
append :linked_dirs, "log", "tmp/pids", "tmp/cache", "tmp/sockets", "vendor/bundle", "public/system", "public/uploads"

回答1:

It looks like rbenv is set to run Ruby 2.3.1. Several places in the log you have RBENV_VERSION="2.3.1". According to the rbenv documentation, you can find out how that was set with rbenv version. If you want to test Ruby 2.4.0, you'll need to point to that version. Alternatively, if you really mean to run on 2.3.1, you'll need to install bundler.
