Undefiniertes Mixin 'global-reset' bei der Bereitstellung auf Heroku

Question

Irgendwelche Ideen, warum dies geschieht, wenn die Bereitstellung auf Heroku:

-----> Preparing app for Rails asset pipeline
       Running: rake assets:precompile
       rake aborted!
       Undefined mixin 'global-reset'.
       (in /tmp/build_b4afrg7i0afu/vendor/bundle/ruby/1.9.1/gems/activeadmin-0.3.4/app/assets/stylesheets/active_admin/_base.css.scss)

       Tasks: TOP => assets:precompile:primary
       (See full trace by running task with --trace)
       Precompiling assets failed, enabling runtime asset compilation
       Injecting rails31_enable_runtime_asset_compilation

Ich habe eine scss-Datei mit:

@import "compass/reset";

aber warum wird es bei der Kompilierung von Assets nicht gefunden? Gibt es eine Möglichkeit, sie einfach nicht zu kompilieren? Es funktioniert gut zur Laufzeit und dieser Schritt erzeugt eine Ausnahme, die in Airbrake und es ist ein Schmerz.

Update : Ich habe rake assets:precompile lokal ausgeführt und festgestellt, dass der Fehler anscheinend von activeadmin erzeugt wird:

$ rake assets:precompile --trace

Ich habe dieses Problem gemeldet, falls es ein Fehler ist .

Answer 1

Prüfen Sie, ob Sie alle der folgenden Punkte erfüllt haben:

Stellen Sie sicher, dass Sie in config/application.rb die Zeile:

config.assets.initialize_on_precompile = false

Wenn Sie andere scss-Dateien als application.css laden, vergewissern Sie sich, dass sie in der Asset-Pipeline enthalten sind. Sie benötigen eine Zeile mit folgendem Wortlaut am Anfang der Datei:

/*= require_self */

Zusätzlich zu Nr. 2 fügen Sie in config/environments/production.rb diese Dateien zur Liste der Assets hinzu. Zum Beispiel, wenn Ihre Datei ist my.scss benötigen Sie eine Zeile wie:

config.assets.precompile += %w( my.css )

Schließlich gibt es einen großartigen Leitfaden unter http://guides.rubyonrails.org/asset_pipeline.html
