我正在跟踪tutorial，使用Capistrano3，Puma Web服务器和nginx在AWS上托管我的Rails 6应用程序。我已经进入最后阶段，但是当我尝试使用Capistrano部署Ruby on Rails应用程序时，总是出现验证失败错误。我使用的命令是cap production deploy。我创建了一个ssh密钥对，将公钥添加到包含应用程序代码的Github存储库中，并将私钥文件路径添加到文件中的以下片段中：/Users/edward/Project/EdwardBlog/blog/config/deploy/production.rb
set :ssh_options, {
forward_agent: true,
auth_methods: %w[publickey],
keys: %w[/Users/edward/.ssh/id_rsa]
}
我可以像ssh -T git@github.com那样进入github，然后再次检查密钥对是否匹配我添加到github帐户中的公共SSH密钥。我还使用ssh-add -l
我也尝试使用密码来部署应用程序，但是当我在提示符下输入github帐户密码时仍然没有运气：
set :ssh_options, {
keys: %w(/Users/edward/.ssh/id_rsa),
forward_agent: true,
auth_methods: %w(password)
}
我不知道为什么不使用本地凭据进行身份验证。将不胜感激任何可能的解决方案或解决方法。
这是我运行命令cap production deploy --trace时的消息：

嵌入到您的部署目标中，而不是与Github的连接中。确保您可以与ubuntu用户一起使用该IP；如果可以，请尝试将SSH密钥添加到您的代理（ubuntu或其他任何方式）中，以确保Capistrano可以与您的代理建立SSH连接部署目标计算机。
