Приложение работало нормально.Это Rails 5.1 с StimulusJS.
Я пытался сделать на сервере
RAILS_ENV=production bundle exec rake assets:precompile
без эффекта.
кажется, что он недоступен
это соответствующий код в production.rb
Rails.application.configure do
# Verifies that versions and hashed value of the package contents in the project's package.json
config.webpacker.check_yarn_integrity = false
# Settings specified here will take precedence over those in config/application.rb.
# Analytics account
# Code is not reloaded between requests.
config.cache_classes = true
# Eager load code on boot. This eager loads most of Rails and
# your application in memory, allowing both threaded web servers
# and those relying on copy on write to perform better.
# Rake tasks automatically ignore this option for performance.
config.eager_load = true
# Full error reports are disabled and caching is turned on.
config.consider_all_requests_local = false
config.action_controller.perform_caching = true
# Disable serving static files from the `/public` folder by default since
# Apache or NGINX already handles this.
config.public_file_server.enabled = ENV['RAILS_SERVE_STATIC_FILES'].present?
# Compress JavaScripts and CSS.
config.assets.js_compressor = :uglifier
# config.assets.css_compressor = :sass
# Do not fallback to assets pipeline if a precompiled asset is missed.
config.assets.compile = true
и на экране консоли отображается ошибка
