Capistrano 没有要加载的文件——部署

Question

当我尝试运行任何 cap 命令时，我收到“没有要加载的此类文件 -- 部署”错误。

这是输出：

这是 Gemfile：

source 'https://rubygems.org'

gem 'rails', '3.2.1'

# Bundle edge Rails instead:
# gem 'rails', :git => 'git://github.com/rails/rails.git'

gem 'sqlite3'
gem 'capistrano'

# Gems used only for assets and not required
# in production environments by default.
group :assets do
  gem 'sass-rails',   '~> 3.2.3'
  gem 'coffee-rails', '~> 3.2.1'

# See https://github.com/sstephenson/execjs#readme for more supported runtimes

end

gem 'jquery-rails'

config/deploy.rb

require 'bundler/capistrano'
set :application, "CapistranoApp" 
set :repository,  "ssh://ubuntu@weaponxo.com/~/projectdir.git"
set :applicationdir, "/var/www/#{application}"
set :domain, "ror.weaponxo.com"


set :scm, :git

# Or: `accurev`, `bzr`, `cvs`, `darcs`, `git`, `mercurial`, `perforce`, `subversion` or `none`

role :web, domain                          # Your HTTP server, Apache/etc
role :app, domain                          # This may be the same as your `Web` server
role :db,  domain, :primary => true # This is where Rails migrations will run

set :deploy_to, applicationdir
set :deploy_via, :remote_cache

# if you're still using the script/reaper helper you will need
# these http://github.com/rails/irs_process_scripts

# If you are using Passenger mod_rails uncomment this:
 namespace :deploy do
   task :start do ; end
   task :stop do ; end
   task :restart, :roles => :app, :except => { :no_release => true } do
     run "#{try_sudo} touch #{File.join(current_path,'tmp','restart.txt')}"
   end
  end

Capfile：

require 'deploy'
# Uncomment if you are using Rails' asset pipeline
# load 'deploy/assets'
Dir['vendor/gems/*/recipes/*.rb','vendor/plugins/*/recipes/*.rb'].each { |plugin| load(plugin) }
load 'config/deploy' # remove this line to skip loading any of the default tasks

我猜“部署”是 Capfile 中对 require 'deploy' 的引用。

我搞砸了什么？

谢谢

编辑

将 Capfile 的第一行改为

load 'deploy' if respond_to?(:namespace) # cap2 differentiator

有效。知道为什么 Capfile 默认附带这个“断”行吗？我需要做与capify . 不同的事情吗？

Answer 1

将您的 capistrano 降级到之前的 2.9.0 版本。

最新的（2.11.0）导致您提到的问题。

Answer 2

试试：

load 'deploy'

（假设您使用的是 capistrano 2）。

我们的 capfile 如下所示：

load 'deploy' if respond_to?(:namespace) # cap2 differentiator

# Uncomment if you are using Rails' asset pipeline
# load 'deploy/assets'

Dir['vendor/gems/*/recipes/*.rb','vendor/plugins/*/recipes/*.rb'].each { |plugin| load(plugin) }

load 'config/deploy' # remove this line to skip loading any of the default tasks

Answer 3

这是我的 Capfile - 试试吧，因为你在 capistrano 2 上

load 'deploy' if respond_to?(:namespace) # cap2 differentiator

# Uncomment if you are using Rails' asset pipeline
# load 'deploy/assets'

Dir['vendor/gems/*/recipes/*.rb','vendor/plugins/*/recipes/*.rb'].each { |plugin| load(plugin) }

load 'config/deploy' # remove this line to skip loading any of the default tasks

Answer 4

我今天刚遇到这个问题。

问题是由于未指定 cap gem 版本，并运行 bundle update，将 cap 更新为 3.* 造成的。

按照这里的建议后，我仍然遇到同样的问题。但是，在仔细检查输出后，我注意到错误来自 cap 3.* not able to load deploy。

这很奇怪，因为我将 cap gem 版本设置为 ~> 2，仍然有来自 cap 3.* 的错误。将 cap 版本降级到 ~> 1 也是如此，错误仍然来自 cap 3.*。

通过从我的 gemset 中完全移除 cap 3.* 来修复它。

我的印象是我可以安装多个 gem 版本，只要在 Gemfile 中指定了我要使用的版本，那就是使用的版本。尽管我的 Gemfile 指定了 ~> 1，但我仍然安装了几个 cap 2.*，版本 2 gem 似乎没有影响，但是也安装了版本 3.*，导致我遇到上述问题OP。

希望这可能对其他人有所帮助。

Answer 5

我今天遇到了这个问题，这是由于我安装了 capistrano 3.* 而这个线程提供了对我有用的解决方案：

Rails 4, Capistrano 3.0.0, cannot load such file -- deploy

Answer 6

所以我遇到了同样的错误。我的错误是在安装 gem 文件后我跳过了安装步骤，而是使用了旧的 2.x 版本示例作为我的 Capfile 和部署文件......

因此，在进行捆绑安装后，请尝试使用命令cap install STAGES=sandbox,qa,production，或您需要的任何阶段。之后，它应该覆盖您的文件。去编辑它添加的文件，你应该很好去。
