由于 ruby​​ 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，不知何故 ruby​​ 消息与突击队并导致部署失败。

以前发生过这种情况，我可以通过将 sprockets gem 降级到 2.8 版本来修复它，但是在此我使用的是 rails 4.2.4，它需要至少 3 的 sprockets 版本。

下面是命令和输出，如果你能帮助我，我会很高兴。

提前致谢

Answer 1

好的。问题是因为 rvm 覆盖 cd 命令以提供有关 Gemfile 中的 ruby​​ 版本控制的一些信息，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 信息也正在返回，结果 deploy 引发了错误。

要解决这个问题，要么

rvm rvmrc warning ignore allGemfiles

可以运行并且可以在服务器范围内禁用 rvm 消息，或者您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 但不知何故它也禁用了 rvm 消息。

希望它也对其他人有所帮助

Rails 4+ 对某些 gem 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
