Не удалось скомпилировать активы

Question

Я нажимаю на приложение, которое я не обновлял в течение нескольких месяцев, и я сталкиваюсь с этой проблемой. Я только изменил несколько переменных в моем коде. Не знаю, почему это внезапно делает это со мной.

! 
!  Precompiling assets failed. 
! 

!  Push rejected, failed to compile Ruby app 

To git@heroku.com:myapp.git 
! [remote rejected] master -> master (pre-receive hook declined) 
error: failed to push some refs to 'git@heroku.com:myapp.git'

Answer 1

Наиболее распространенные причины проблем перекомпиляции активов можно найти here на странице поддержки Heroku.

На основании упоминания Postgres в сообщении об ошибке, я бы попытаться изменить следующую строку в конфигурационном/application.rb к ложной так: config.assets.initialize_on_precompile = false.

Answer 2

Вы должны предотвратить инициализации приложения и подключения к базе данных, гарантируя, что следующая строка в вашем конфигурационном/application.rb:

config.assets.initialize_on_precompile = false
