Bug 56467

Summary: Невозможно создать новый проект Ruby-On-Rails
Product: Sisyphus Reporter: Артем Добровинский <dobrowins>
Component: railsAssignee: majioa <majioa>
Status: NEW --- QA Contact: qa-sisyphus
Severity: normal    
Priority: P5 CC: admsasha, antohami, cas, imz, led, majioa, mike, nbr, pav, rider, stalker
Version: unstable   
Hardware: x86_64   
OS: Linux   

Description Артем Добровинский 2025-10-18 14:39:15 MSK 
Делаю всё по инструкции https://wiki.altlinux.org/Ruby_on_Rails_QuickStart
Зависимости устанавливаются. Во время создания проекта bundler уходит в неизвестную ошибку. rvm install ruby нужной версии не помогает.
Подскажите, пожалуйста, как создать проект и начать разработку.

bundle config set --local path 'vendor/bundle' не помогает в решении проблемы
Comment 2 Артем Добровинский 2025-10-18 15:00:35 MSK 
Если сделать всё не по инструкции в wiki, а официальной https://guides.rubyonrails.org/install_ruby_on_rails.html#install-ruby-on-ubuntu всё работает.
Возможно, стоит править wiki.
