Klejnot ruby, powodujący, że serwer nie działa: nie można załadować takiego pliku - xmlrpc/client (LoadError)

Question

Jak wskazuje tytuł, próbuję skonfigurować system Ubuntu 16.04 do pracy z aplikacjami railsowymi. Kiedy skomentuję klejnot mgły, serwer uruchomi się lokalnie, a przy pozostawionym klejnocie pojawi się komunikat o błędzie poniżej. Googling nie zapewnia niczego, ponieważ nie mogę znaleźć nikogo innego z tym samym błędem co ja i nie mogę po prostu usunąć tego klejnotu z aplikacji, gdy jest potrzebna.

Pełną wiadomość jest jak poniżej:

Jeśli ktoś może mi powiedzieć jak to albo download/zainstalować klienta xmlrpc lub obejść ten problem, że będą mile widziane.

Answer 1

Problem polega na tym, że począwszy od wersji Ruby 2.4.0, biblioteka xmlrpc, która była wcześniej dostarczana z rubinem, została wyodrębniona do perełka. Więc musisz po prostu dodać to do swojego pliku gem i ponownie spakować.

gem 'xmlrpc'
