我在部署方面遇到了一些问题。 rails版本为4.2.4， capistrano版本为3.4.0。 我不明白出了什么问题。有人可以帮我吗？

$ bundle exec cap production deploy --trace
** 调用 production (第一次)
** 执行 production
** 调用 load:defaults (第一次)
** 执行 load:defaults
cap 中止!

你是如何创建这个配置的？如果你使用 cap install，通常不会出现这种情况。 - will_in_wi

您的 deploy.rb 文件不应包含 require 或 load 行。备份您的配置，删除您的 Capfile、config/deploy.rb 和 config/deploy/*，然后运行 cap install。根据个人喜好修改生成的配置文件。

请确保在项目目录下直接有Capfile文件。如果Capfile包含像require 'bundler/capistrano'这样的一行，请将其删除，这样就可以正常工作了。

请将以下内容添加到您的Capfile文件中，而不是config/deploy.rb文件中：
``` require 'bundler/capistrano' ```
