Этот вопрос не продлится, если вы не предоставите гораздо больше информации. Нам нужно увидеть код, где произошла ошибка, и любые данные, необходимые для воссоздания проблемы. См. Http://sscce.org/ –

, как я помню, приветственное слово приходит по умолчанию в routes.rb. Посмотрите на это и разместите свой код здесь – Bijendra

Я думаю, что новичок может получить этот тип ошибок. Вот как один учить. Респект ..! – Jay

uninitialized constant Wellcome (NameError)

ли вы типа "Велком" где-нибудь? Возможно, в /home/ajay/ruby_rails_practical_demo/ftuse/ft1/config/routes.rb? Сообщения об ошибках стараются помочь!

yup я поставил неправильный маршрут. Теперь я изменил эту строку, все еще эта ошибка приходит. /usr/lib/ruby/1.9.1/webrick/utils.rb:85:in 'initialize ': адрес уже используется - bind (2) (Errno :: EADDRINUSE) –

Сетевой адрес, который вы пытаетесь использовать для сервера, уже используется. –

Приложение не находит постоянную Wellcome. Я предполагаю, что это происходит из-за опечатки. Найдите код для «wellcome» или «Wellcome» и исправьте это.
