Я работаю над учебником, я пытаюсь сделать шаг1.4.2.

Я пробовал несколько вещей, но ни одна из них не работала, когда я искал в Интернете "NoMethodError: неопределенный метод` configure '". Я просмотрел все ссылки и несколько похожих поисков, которые пришли, но ни один из них не работал.

В книге говорится, что сделать это:

# This should only be used if your Heroku deploy fails without it.
$ rake assets:precompile
$ git add .
$ git commit -m "Add precompiled assets for Heroku"

но это не сработало или я не получил его на работу

Вот реальная проблема, когда я делаю

$ git push heroku master

это результат.

james@ubuntu:~/rails_projects/first_app$ git push heroku master
