"Ich konnte den Wächter nicht starten", als ich die Angular CLI App auf Heroku installieren wollte

Question

Ich versuche eine Rails/Angular App auf Heroku zu installieren. Wenn ich dies tun, erhalte ich:

Wenn es die post versucht erhalte ich:

Could not start watchman; falling back to NodeWatcher for file system events.

ng build arbeitet lokal in Ordnung. Warum nicht auf Heroku?

Answer 1

Ich änderte "postinstall": "ng build" zu "heroku-postbuild": "ng build" und das Problem ging weg.

(Um genau zu sein, blieb die Watchman-Warnung bestehen, aber der Build stoppte versagt, was die Hauptsache war, um die ich mich wirklich sorgte.)
