fonctionne la version locale, mais la version de production ne

Question

Contexte

A l'origine, mon application fonctionnait correctement à la fois sur mon serveur local et de la production (Heroku). J'ai alors fait un changement que j'ai prématurément poussé à Heroku; le changement a cassé la version sur la production ayant pour résultat l'affichage de l'erreur "500". L'application fonctionnait toujours sur mon serveur local.

Pour résoudre ce problème, j'ai exécuté la commande heroku rollback pour revenir à la version de travail antérieure en production. La version de production fonctionnait maintenant. Pour m'assurer que mes copies locales et de production étaient synchronisées avec les versions de travail, je pensais simplement exécuter la commande heroku git:clone -a myapp afin de pouvoir remplacer ma copie locale par la copie de production en cours.

Problème

Après avoir remplacé ma copie locale avec la copie de travail de la production, je puis essayé de pousser à Heroku (pour vérifier que tout fonctionnait). Ma version locale fonctionne toujours correctement; Toutefois, la version de production affiche simplement l'erreur "505" et l'exécution heroku rollback ne revient plus à la version de travail antérieure. Comment puis-je faire fonctionner la version de production?

Toutes mes excuses pour l'explication tortueuse. Toute aide serait grandement appréciée!

MISE À JOUR:

J'étais curieux de savoir si la création d'une nouvelle télécommande Heroku résoudrait le problème si J'ai supprimé http://nameless-brook-8163.herokuapp.com/ et définir la nouvelle télécommande à http://secret-brushlands-9122.herokuapp.com/. Malheureusement, le problème persiste.

j'ai couru « heroku exécuter rake db: migrate » par une recommandation ci-dessous et a obtenu le résultat suivant:

heroku run rake db:migrate

Le problème semble être un commentaire ouvert (* /) dans l'un de mes fichiers CSS. Cela est arrivé à mon attention quand je tentais de compiler les actifs avec la commande:

RAILS_ENV=production bundle exec rake assets:precompile 

et obtenu l'erreur ...

rake aborted! 
Invalid CSS after "*/": expected identifier, was "/* Sections" 

J'ai supprimé l'étranger « */», a forcé un coup de pouce à Heroku (git push -f heroku master), supprimé index.html et voila la bonne page a été servie.

Merci à tous pour l'aide et des recommandations!
