ruby-on-rails - Ruby Rails - Cloud9 - (SocketError)

Question

尝试在 C9.io 中启动我的 Rails 应用程序时，我看到下面的套接字错误。我不确定如何纠正这个问题。有什么想法吗？

• ruby 2.3.0p0(2015-12-25 修订版 53290)[x86_64-linux]
• rails 4.2.5

• Cloud9 集成开发环境

尝试在 cloud9 上启动我的 Sinatra 应用程序时，我遇到了同样的错误。事实证明，我正在使用根用户 (su) 运行命令:$ bundle exec rackup -p $PORT -o $IP。尝试在普通用户上运行它。
