Fehler beim Drücken der Rails-App auf Heroku

Question

Ich bin komplett neu in Ruby on Rails. Ich habe versucht, ein "Hallo, Welt!" Web-App nach Hartls Tutorial, aber ich konnte die App nicht auf Heroku bereitstellen. Ich habe die Dateien zu Git hinzugefügt und sie auch übernommen. Außerdem läuft die App auf meinem lokalen Rechner einwandfrei. Hier

ist das, was ich bekomme, wenn ich git push heroku master laufen: -

[jobsism10-Lenovo-G580]: ~/Downloads/Web Development/Rails Projects/hello_app$ git push heroku master

Welche Sie letztlich aktualisiert Juwel sass-Schienen auf den neuesten. Oder Sie können die Version in Ihrer gemfile höher als 5.0.1 eingeben.
