sassc 2.4.0 при установке gem bootstrap — не удается установить

#ruby-on-rails #ruby #bootstrap-4

#ruby-on-rails #ruby #bootstrap-4

Вопрос:

когда я делаю

 gem 'bootstrap', '~> 4.1.3'

и затем

 bundle install

и это показывает мне

 An error occurred while installing sassc (2.4.0), and Bundler cannot continue.
Make sure that `gem install sassc -v '2.4.0' --source 'https://rubygems.org/'`
succeeds before bundling.

In Gemfile:
  sass-rails was resolved to 6.0.0, which depends on
    sassc-rails was resolved to 2.1.2, which depends on
      sassc

Комментарии:

1. Каков результат запуска gem install sassc -v '2.4.0' --source 'https://rubygems.org/'

2. @TomHarvey я добавил к сообщению

Ответ №1:

Я бы рекомендовал вам избегать использования Ruby 2.3.3. Просто возьмите 2.4.0 или выше.

Ваша ошибка заключалась в использовании Rails 5 с 2.3.3. Это просто не сработало бы — существует много конфликтов, особенно с зависимостями nokori, sqlite3, sass и tzinfo. Понизьте Rails до 4.2.8 или 4.2.11.

Могу ли я также узнать, какая ОС? Если Windows, избегайте использования Railsinstaller — все это сломано. Вместо этого используйте Rubyinstaller Devkit — могут появляться всплывающие окна о sql-адаптере, вы можете исправить это, используя это в Gemfile:

 gem 'sqlite3', platforms: [:mingw, :mswin, :x64_mingw, :jruby]
