ruby-on-rails - Rails 服务器无法运行

Question

过去 2 天我一直在尝试设置 Ruby on Rails。我让他们在一个阶段运行但打破了它。我已经通过 RVM 重新安装了 Ruby 和 Rails，我正在尝试继续我一直在研究的教程。我遇到的问题是，当我在 Rails 应用程序目录中运行命令“rails s”时，我收到以下错误消息:

有人可以向我解释这个错误吗？我越来越累了。提前致谢。

您在没有 openssl 依赖项的情况下编译了 ruby​​。做

rvm requirements

(或 rvm notes 如果您使用的是没有rvm 要求 的旧版本 rvm)并查看您需要在系统中安装什么(例如，如果您正在运行 ubuntu，通常这些是 apt-get 命令)，然后重新编译您的 ruby​​ 安装通过

rvm remove 1.9.2
rvm install 1.9.2
