[rails] bootstrap 적용 후 production에서 동작 안할 때

develop 모드에서는 지정해둔 bootstrap 이 잘 나오는데,

rails s -e production

으로하면 css가 전혀 안 먹히고

이런 오류가 난다.

페이지는 뜨지만, bootstrap 이 안 먹힌 채로 표시된다.

RAILS_ENV=production bundle exec rake assets:precompile

이걸 해보라고 해서 해봐도 아무런 오류가 없었다.

# Disable Rails's static asset server (Apache or nginx will already do this).
config.serve_static_assets = true

이걸 false에서 true 로 바꿨더니 잘 된다.

어딘가에서는 Gemfile에서 group :assets 에 넣으라고 하는데, 레일스 4.0부터는 저거 없어졌다고 한다.
