Мое угловое приложение нельзя развернуть на героку. Как я могу это исправить?

Question

Я создал угловое приложение, которое хочу развернуть на heroku, но сборка не удалась. Я выполнил шаги, предоставленные https://itnext.io/how-to-deploy-angular-application-to-heroku-1d56e09c5147, и не получил его на работу. Какие изменения необходимы для этой работы?

Here's my build log

Ресурс, который вы указали, дает альтернативу команде postinstall.

Попробуйте заменить:

"postinstall": "ng build --aot -prod"

на:

"heroku-postbuild": "ng build --prod"
