Ошибка сервера Rails

Когда я запускаю свой Rail Server для Project, выдает ошибку вроде

sahil@sahil-M:~/sites/tasks$ rails s
Could not find gem 'sqlite3 (>= 0, runtime)' in any of the gem sources listed in your Gemfile.
Run `bundle install` to install missing gems.

и в то время как я иду для комплекта установки, это дает другую ошибку

Решение

Попробуй это

  sudo apt-get install ruby1.8-dev libsqlite3-ruby libsqlite3-dev
Источник

Вам необходимо установить ruby1.8-dev пакет по мере необходимости на вашем дистрибутиве.

В Ubuntu/Debian войдите в систему как root на консоли и установите его так:

apt-get install ruby1.8-dev

Или это может быть просто ruby-dev, Попробуй если ruby1.8-dev не работает
