搞砸了我的 Rails 依赖项：[

Question

所以我试图通过将以下行添加到我的环境配置中来配置我的 rails 3.0.9 应用程序以使用 HTTPS 和 SSL

config.middleware.insert_before ActionDispatch::Static, "Rack::SSL"

并在我的 Gemfile 中定义 Rack::SSL 依赖项

gem 'rack-ssl', :require => 'rack/ssl'

由于某种原因不起作用，所以我尝试先通过撤消上述操作来回滚 gem 依赖项，然后

gem cleanup

那没用，所以我做了以下愚蠢的事情：

gem uninstall rack-ssl

和

gem uninstall railties

卸载了 railties 3.0.9 和 3.1.0。

显然我在此过程中做了一些坏事，但现在我无法运行 rails 并且出现以下错误：

谁能帮助我？我尝试卸载并重新安装 rails gem，但没有任何效果。

编辑：我意识到切换到系统版本的 ruby​​（从我的 rvm 默认）解决了这个问题，所以我卸载并重新安装了 rvm、ruby、rails 和我所有的 gem。这并没有完全解决问题，但我决定快速查看一下我的 Gemfile.lock 并注意到 rack-ssl 仍然在那里。删除就行了。

你应该可以用gem install railties -v 3.0.9恢复它
