我试图在一个rails应用程序中首次获得Capistrano的运行.我有一个
linux服务器运行Ubuntu 12.04,Nginx,独角兽和rails,但是,我似乎正在遇到一些问题.我也使用Capistrano 3.0.0,rails 3.2.14,bundler 1.4.0&红宝石1.9.3p448使用RVM.
我只有一个生产阶段设置,在这个时间点,我只关心Capistrano与我的服务器通信,并推送我的代码从github(没有迁移和捆绑等).
当我尝试命令帽生产部署：检查或cap生产部署：安装程序(似乎已被弃用？)与下面的设置,我得到以下错误msg：
我不太确定从哪里开始出现这个错误,而谷歌并不建议太多.我已经尝试添加rvm-capistrano宝石,但没有用.如何修改我的代码来解决这个错误？

Dir.glob('lib/capistrano/tasks/*.cap').each { |r| import r }
编辑在对捆绑机中capistrano.rb的违规行进行查看后,它提到要对deploy.rb添加require’bundler / deployment’,这似乎摆脱了capistrano实例的错误.
注意降级到capistrano 2.15.5,摆脱了错误.
解决方法
首先,capistrano 3有几个变化.
见发行说明： http://www.capistranorb.com/2013/06/01/release-announcement.html
见发行说明： http://www.capistranorb.com/2013/06/01/release-announcement.html
也请阅读自述文件.
https://github.com/capistrano/capistrano/blob/master/README.md
Capistrano 3已经将捆绑程序集成移植到gem中.解决您的问题：
1. Uncomment require 'capistrano/bundler' from capify. 2. add gem 'capistrano-bundler' to your gemfile. 3. Go through the comments in capify file and uncomment whichever module you require.
哦,如果你不想使用bundler,请删除第一行：require“bundler / capistrano”.容易如此
此外,您现在不能像以前的方式那样使用变量.不要直接读取它,请使用fetch(：application)来读取变量.
我会更容易回到capistrano v2.
