Rails 4, Capistrano 3.0.0, cannot load such file -- deploy
提问by markhorrocks
I just ran bundle update and capistrano got updated to 3.0.0 but now when I run cap deploy I get an error and can't figure out how to fix this. I have been updating my server every day without problem until this update.
我刚刚运行了 bundle update 并且 capistrano 更新到了 3.0.0 但是现在当我运行 cap deploy 我得到一个错误并且无法弄清楚如何解决这个问题。在此更新之前，我每天都在毫无问题地更新我的服务器。
cap aborted!

I had to run
gem uninstall capistrano
我不得不跑
gem uninstall capistrano
then update the gemfile with
gem 'capistrano', '~> 2.15'
然后用
gem 'capistrano', '~> 2.15'
and then run to reinstall the correct version again with
bundle update capistrano
然后运行以再次重新安装正确的版本
bundle update capistrano

I had to gem uninstall capistrano and selected version 3.0.0
我不得不 gem 卸载 capistrano 并选择版本 3.0.0
(i.e. downgraded the gem to 2.x)
（即将 gem 降级到 2.x）
回答by stebooks
Make sure you are using bundle exec (most likely you have multiple gem versions of capistrano)
确保您使用的是 bundle exec（很可能您有多个 gem 版本的 capistrano）
i.e.
IE
bundle exec cap -T
bundle exec cap -T

Instead of downgrading to Capistrano 2 use the new configuration from the current version.
使用当前版本的新配置，而不是降级到 Capistrano 2。
require "capistrano/bundler"
require "capistrano/rails/assets"
require "capistrano/rails/migrations"
See also this nice posting, which summarises the differences between Capistrano 2 and 3.
另请参阅这篇不错的帖子，其中总结了 Capistrano 2 和 3 之间的差异。

Add the related gems to your Gemfile
将相关的宝石添加到您的 Gemfile
i.e. for
即为
gem 'capistrano-bundler' # for capistrano/bundler
gem 'capistrano-rails' # for capistrano/rails/*
Do not downgrade to 2.x for this.
不要为此降级到 2.x。

I had this problem today and pastullo's solution above fixed it except that I had to run gem uninstall capistrano (as markhorrocks answered) not bundle uninstall capistrano.
我今天遇到了这个问题，上面的 Pastullo 解决方案修复了它，只是我必须运行 gem uninstall capistrano （如 markhorrocks 回答）而不是 bundle uninstall capistrano。
I also found this blog on bundler very useful: http://viget.com/extend/bundler-best-practices

The fastest way to fix this I have found is to backup the cap files (Capfile, config/deploy.rb, and config/deploy/*.rb) and then re capify (it's no longer called "capify"):
我发现解决此问题的最快方法是备份 cap 文件（Capfile、config/deploy.rb 和 config/deploy/*.rb），然后重新进行 capify（不再称为“capify”）：
bundle exec cap install STAGES=staging,production
Then recreate your cap files from your backup. It will take you 5 minutes to do this and you'll be over the major Capistrano upgrade hump.
然后从备份中重新创建 cap 文件。完成此操作需要 5 分钟，您将完成主要的 Capistrano 升级过程。
