cap 部署 + rbenv：捆绑：找不到命令

我正在关注https://gorails.com/deploy/ubuntu/16.04

我正在运行：“bundle exec cap 生产部署” 并收到以下错误：

“gem list”显示：两台机器上的bundler (1.14.6)，以及我的生产机器和服务器上的ruby 2.4.0。 如何进行？

我正在发布我的 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 }

我的部署.rb：

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

set :application, "deploy_test1"
set :repo_url, "[email protected]: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"

看起来像rbenv设置为运行 Ruby 2.3.1。您在日志中的几个位置RBENV_VERSION="2.3.1"。根据rbenv 文档，你可以了解它是如何设置的rbenv version。如果您想测试 Ruby 2.4.0，则需要指向该版本。或者，如果您确实想在 2.3.1 上运行，则需要安装捆绑程序。
