Rails-Debug-Assets: Vorkompilierung: Wie erkenne ich fehlerhafte Dateien?

Question

Ich bin ein bisschen verzweifelt; habe versucht, dieses Problem seit Tagen zu debuggen. JEDER hat irgendeine Idee, wie man Fehler findet? Identifizieren Sie möglicherweise die Datei (en), die das Codierungsproblem verursachen?

FWIW: Das funktioniert in dev Umgebung: RAILS_ENV=production bundle exec rake assets:precompile --trace

Aber dies nicht gelingt auf 'Produktion' Server ... keine Ahnung, wie die Fehlersuche beginnen:

$ RAILS_ENV=production RAILS_GROUPS=assets bundle exec rake assets:precompile --trace 
** Invoke assets:precompile (first_time) 
** Invoke assets:environment (first_time) 
** Execute assets:environment 
** Invoke environment (first_time) 
** Execute environment 
** Execute assets:precompile

Answer 1

Ich würde einfach einen Zyklus des Entfernens einer Datei aus Ihrem Manifest starten und dann versuchen, zu implementieren. Wenn das nicht funktionierte, entfernte ich die nächste Datei aus dem Manifest und so weiter, bis ich den Fehler gefunden hatte, der das Problem verursacht hatte.

Answer 2

Gerade mit ähnlichem Problem konfrontiert - InvalidByteSequenceError während Assets: Vorkompilierung. Was ich getan habe, war - ich habe den Ketten-Edelstein-Code ein bisschen bearbeitet, um einige Debug-Informationen "zu pushen", wobei gerade der aktuelle Dateiname verarbeitet wird. Dann habe ich Precompile erneut ausgeführt, die Datei basierend auf der Debug-Ausgabe gefunden und repariert. Dann habe ich natürlich die Edelstein-Änderungen rückgängig gemacht. Sie können den gleichen Ansatz verwenden, da Sie das Backtrace haben. Darüber hinaus könnten Sie sogar die asscès: precompile task debuggen (entweder durch Inline-Debugger oder durch Ihre Lieblings-IDE. Hoffe, das hilft!
