由于红宝石消息，Capistrano部署失败

Question

我正在尝试使用capistrano 3.4.0和capistrano-rails 1.1.6部署我的应用程序，但似乎在资产清单期间，当复制.sprockets-manifest.json的命令运行时，ruby消息与Commandos混合并导致部署失败。

这是以前发生的，我可以通过将链轮gem降级到2.8版来修复它，但是在此我使用的是Rails 4.2.4，它至少需要一个链轮版本3。

下面是命令和输出，如果您能帮助我，我会很高兴。

提前致谢

Answer 1

好。 造成此问题的原因是，rvm覆盖了cd命令，以便提供有关Gemfile中的ruby版本控制的某些信息，并且当capistrano-rails运行清单备份任务时，它运行cd命令以获取应用程序项目文件夹和rvm信息还返回并且部署导致了en错误。

为了解决这个问题，

rvm rvmrc warning ignore allGemfiles

可以在整个服务器范围内运行和禁用rvm消息，也可以在项目的根路径中创建一个名为.ruby-version的文件，并在其中设置ruby版本。 例如：

2.2.4

据我了解，.ruby-version用于rbenv，但是某种程度上它也禁用了rvm消息。

希望它也能帮助别人

Rails 4+对某些宝石的特定版本非常挑剔。 尝试将您的gemfile更新为以下内容：

group :development, :test do
  gem 'capistrano', '~> 3.4.0'
  gem 'capistrano-rvm'
  gem 'capistrano-bundler', '~> 1.1.2'
  gem 'capistrano-rails', '~> 1.1'
  gem 'capistrano-passenger'
end
