我只是想通过 railsapps.org Learn Ruby on Rails网上预定。我已经安装了所有东西，但一直停留在教程中的“启动 Web 服务器”。

当我执行“$ rails server”时，我得到以下信息:

trick420$ rails server
=> Booting WEBrick
=> Rails 4.1.0 application starting in development on http://0.0.0.0:3000
=> Run `rails server -h` for more startup options
=> Notice: server is listening on all interfaces (0.0.0.0). Consider using 127.0.0.1 (--binding option)
=> Ctrl-C to shutdown server

我不知道问题是什么，因为此时我对 Rails 或 Ruby 一无所知。相当的进入壁垒，不是吗？ gem sprockets-rails 似乎存在问题，但我不知道如何处理该问题或从哪里开始，因为我什至还没有开始使用 rails。

最佳答案

https://github.com/rails/sprockets-rails/issues/131

等待修复发布或简单地添加到您的 Gemfile

gem 'sprockets-rails', :require => 'sprockets/rails/version'
