由于 ruby 条消息，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，当命令复制 .sprockets-manifest.json 运行，不知何故 ruby 消息与突击队员混合并导致部署失败。

以前发生过这种情况，我可以通过将 sprockets gem 降级到 2.8 版来修复它，但是我使用的是 rails 4.2.4，它至少需要 sprockets 版本 3。

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

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

Answer 2

好的。这个问题是因为 rvm 覆盖了 cd 命令，以便在 Gemfile 中提供一些关于 ruby 版本控制的信息，当 capistrano-rails 运行s 清单备份任务时，它运行s 一个进入应用程序项目文件夹的 cd 命令，并且 rvm 信息也返回并且部署因此引发了 en 错误。

要解决这个问题，

rvm rvmrc warning ignore allGemfiles

可以是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 的文件并设置 ruby里面的版本。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。

希望它对其他人也有帮助
