Не удается развернуть приложение Heroku (ошибка npm! Состояние выхода ELIFECYCLE 1)

#javascript #node.js #reactjs #heroku #redis

Вопрос:

Я пытался развернуть блокчейн — приложение на Heroku-оно написано на JavaScript и включает в себя node.js, повторите и отреагируйте. Хотя приложение полностью функционирует на локальном порту, я получаю сложную ошибку при запуске журналов heroku-хвост в терминале. Вот ошибка (я знаю, что она содержится в фрагменте кода, но мне показалось, что это сделает его более читаемым):

Я просмотрел другие сообщения, касающиеся этой проблемы, но все они немного неясны. Если бы кто-нибудь мог мне помочь, это было бы здорово!

Ответ №1:

Эта ошибка говорит о том, что приложение ожидает redis установки, но это не так:

Ошибка: Не удается найти модуль «redis»

Исправьте это, установив пакет, чтобы он стал зависимостью в вашем package.json :

 npm install redis

1. Установка redis с помощью npm изменила ошибку, но только немного — флаг h10, похоже, не отображается, но он все еще не может найти модуль redis. Я обновил фрагмент ошибки в исходном комментарии с тем, что он показывает сейчас.

2. Для меня все еще похоже на ту же проблему. Вы продвигаете обновленный пакет.json? Я бы посоветовал попытаться воспроизвести проблему локально, удалив ваш глобально установленный redis.

3. Первоначально я установил redis через Homebrew — я не могу удалить его, потому что остальная часть моего приложения, которая зависит от redis Homebrew, развалится. Я позаботился о том, чтобы сохранить модуль npm как зависимость от файла package.json, но пока безуспешно…

4. Можете ли вы предоставить ссылку на репозиторий?

Ответ №2:

Я не вижу пакета redis в зависимостях в вашем файле package.json, поэтому это может быть проблемой

попробуйте переустановить пакет npm i redis и снова развернуть его.

1. Не повезло — я установил redis в качестве зависимости, но он по-прежнему отображает ту же ошибку. Первоначально я установил redis через homebrew, так что, возможно, именно поэтому он не появился в файле package.json… но даже когда я внес это изменение, Heroku все еще не может обнаружить модуль.
