Я в процессе обновления моего старого приложения rails 4.2 до rails 5. В настоящее время я пытаюсь заставить его работать на 5.1. Когда я пытаюсь получить доступ к странице моего приложения в процессе разработки, кажется, что он загружается нормально и начинает отображаться. По браузеру никогда не получает ответ от сервера и сервер просто перестает выводить в журналы. Я не могу понять, что происходит.
Как я могу далее отлаживать, почему он зависает и никогда не отвечает?
Вывод rails s:
=> Booting Puma
=> Rails 5.1.7 application starting in development
=> Run `rails server -h` for more startup options
Puma starting in single mode...

Он просто останавливается на Точка, в которой, по-видимому, выполняется обработка в рельсах, должна отправлять ответ браузеру. Вместо этого он просто зависает, как будто у меня есть, например, binding.pry в коде - но у меня нет. И ничего не выбрасывается в логах. Я даже не могу остановить сервер, я должен убить его вручную. Процессор ruby процесса простаивает на 0%.
rails console прекрасно работает между прочим.
Что еще я могу сделать, чтобы выяснить, где он застревает?
UDPATE
У меня есть подозрение, что это может быть связано с компиляцией активов. В моей старой ветке rails 4.2, после достижения определенной точки в журнале, она начала компилировать ресурсы на лету в процессе разработки, однако в ветке rails 5.2 этого не происходит. Теперь при запуске: bin/rails assets:precompile Я получаю:
