Ruby Rails - Cloud9 - (SocketError)

Question

При попытке запустить приложение Rails в C9.io, я вижу Socket Error ниже. Я не уверен, как исправить эту проблему. Есть идеи?

• Рельсы 4.2.5

• Cloud9 IDE

Answer 1

Я получил ту же ошибку, когда пытался запустить мое приложение Sinatra на cloud9. Оказалось, что я выполнял команду: $ bundle exec rackup -p $PORT -o $IP с пользователем root (su). Попробуйте запустить его у обычного пользователя.
