Rails Console не може да намери activesupport-4.1.2, въпреки че е инсталиран

Когато стартирам сървъра Rails 4.1.2, не получавам грешки.

Въпреки това, ако стартирам „rails c“, получавам следната грешка:

Could not find activesupport-4.1.2 in any of the sources
Run `bundle install` to install missing gems.

Странното е, че activesupport-4.1.2 е инсталиран и е посочен в Gemfile.lock. Опитах „актуализация на пакет“, както и изтриване на Gemfile.lock и стартиране на „инсталиране на пакет“. Също така се опитах да посоча тази конкретна версия на ActiveSupport в моя Rails gemfile, но това не ме доведе до никъде.

Наистина бих искал да използвам най-новите Rails, но изглежда доста гадно, че не мога да използвам конзолата.

FIY: Използвам Ruby 2.1.2p95 в Linux с RVM.

РЕДАКТИРАНЕ: Деинсталирах всички скъпоценни камъни за активна поддръжка и преинсталирах 4.1.2. Ето какво казва „gem list activesupport“:

*** LOCAL GEMS ***

activesupport (4.1.2)

Същия проблем.
