使用 rmv 更改 ruby 和 rails 版本时，更改项目配置的正确步骤是什么。
例如，我必须更改 deploy.rb set :rvm_ruby_version, '2.4.0@5.1'，但还有什么？
我无法让 Capistrano 使用正确的 rvm gemset，并且总是尝试使用旧的 rvm gemset bundle install
我是否必须更改生产服务器中的某些内容？我认为是这样，但按照某种顺序，在部署之前和部署之后进行一些其他更改......？
我已经尝试了 capistrano-rvm、rvm-capistrano，最后是 rvm1-capistrano3
当我运行 cap production depoly 时，我得到了这些错误，都围绕着“Could not determine which Ruby to use”

谢谢
最佳答案
在 Rails.root 中创建名称为 .ruby-version 并包含以下内容的文件:
2.3.3
或者你想要的任何版本。当您或 capistrano cd 到根文件夹时，rvm 将根据文件内容更改 ruby 版本
