无法加载这样的文件 - bundler/setup - Capistrano

Question

我正在尝试通过 Capistrano 学习部署。当我运行部署脚本时，除迁移外一切正常。

我收到以下错误。

INFO [175f4b0b] Running /usr/bin/env rake db:migrate as 

prajeesh@xx.x.x.xxx
DEBUG [175f4b0b] Command: cd /home/prajeesh/Desktop/projects/capistrano_staging/current && ( RAILS_ENV=development /usr/bin/env rake db:migrate )
DEBUG [175f4b0b]    rake aborted!
DEBUG [175f4b0b]    

cannot load such file -- bundler/setup

Capfile

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

# Include default deployment tasks
require 'capistrano/deploy'
#require 'capistrano/rails/assets'
require 'capistrano/rails/migrations'

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

部署文件

# config valid only for current version of Capistrano
lock '3.4.0'

set :application, 'capistrano_study'
set :repo_url, 'https://github.com/xxxxxxxx/capistrano_study.git'

# config valid only for current version of Capistrano
set :stages, ["development","staging", "production"]
set :default_stage, "development"
set :user, "prajeesh"
after "deploy:updated", "deploy:migrate"

 set :keep_releases, 5

namespace :deploy do
  after :restart, :clear_cache do
    on roles(:web), in: :groups, limit: 3, wait: 10 do
      # Here we can do anything such as:
      # within release_path do
      #   execute :rake, 'cache:clear'
      # end
    end
  end
end

如果我运行命令 RAILS_ENV=development /usr/bin/env rake db:migrate 直接从项目路径，迁移是运行ning 但通过 capistrano它不工作。

如有任何帮助，我们将不胜感激。

Answer 1

这是你的答案：

安装以下 gem：

gem 'capistrano-rails', '~> 1.1'

并需要打包任务

# Capfile
require 'capistrano/bundler' # Rails needs Bundler, right?
require 'capistrano/rails/assets'
require 'capistrano/rails/migrations'

Answer 2

我所要做的就是安装 gem 'capistrano-rvm' 并在 cap 文件中要求它
