Ruby on rails mit Einhorn nicht lesbare Datei

Question

Ich versuche in Ruby on Rails Umgebung zu bauen, aber wenn ich den Einhornstatus überprüfe, gibt es mir den folgenden Fehler und ich weiß nicht, was zu tun ist. Ich habe den Pfad zum config.rb überprüft und es ist da.

Answer 1

Vergewissern Sie sich, dass Sie unicorn über Befehl ausführen:

bundle exec unicorn -D -E <environment> -c config/unicorn.rb 

Und wenn es nicht funktioniert, geben Sie bitte Ihre Datei config/unicorn.rb

Answer 2

Datei teilen Das Vorhandensein auf dem Pfad bedeutet nicht, dass es für einen bestimmten Benutzer lesbar ist. Überprüfen Sie, ob der Benutzer, unter dem Sie Einhorn betreiben, Zugriff auf die Dateien und Verzeichnisse hat. Normalerweise sind Code-Besitzer und Unicorn-Benutzer gleich, also chown -R that_username:that_username /path/to/app/source entsprechend.
