大佬教程收集整理的这篇文章主要介绍了ruby-on-rails – Capistrano :: Configuration:Class的未定义方法`instance’,大佬教程大佬觉得挺不错的,现在分享给大家,也给大家做个参考。
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?

Capfile
# Load DSL and Setup Up Stages require 'capistrano/setup' # Includes default deployment tasks require 'capistrano/deploy' # require 'capistrano/rvm' # require 'capistrano/rbenv' # require 'capistrano/chruby' # require 'capistrano/bundler' # require 'capistrano/rails/assets' # require 'capistrano/rails/migrations' # Loads custom tasks from `lib/capistrano/tasks' if you have any defined. 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.
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.
