Tasks: TOP => production

我的Capfile

require 'capistrano/setup'
require 'capistrano/deploy'

require 'capistrano/rbenv'
require 'capistrano/bundler'
require 'capistrano/rails/assets'
require 'capistrano/rails/migrations'

Dir.glob('lib/capistrano/tasks/*.rake').each { |r| import r }

的Gemfile

gem 'capistrano
gem 'capistrano-bundler'
gem 'capistrano-rails'
gem 'capistrano-rbenv'

我的deploy.rb

require 'bundler/capistrano'
load 'deploy/assets'
set :repository,  "git@bitbucket.org:test/test.git"

Answer 1

您的deploy.rb不应包含require或load行。备份配置，删除Capfile，config/deploy.rb和config/deploy/*，然后运行cap install。修改生成的配置文件以便尝试。

Answer 2

确保您直接在项目目录下有Capfile。如果Capfile包含类似require 'bundler/capistrano'

的行

删除它，它应该工作。

Answer 3

将以下内容添加到Capfile中，而不是config / deploy.rb：

require 'bundler/capistrano'
