Tasks: TOP => assets:precompile 

Błąd jest spowodowany w parser.rb w Sass. Nie do końca rozumiemy, co oznacza ten błąd. Próbowaliśmy wdrożyć na serwerze produkcyjnym, a powyższa komenda prekompilacji zasobów działała pomyślnie bez żadnego błędu. Czy ktoś może nam pomóc zrozumieć błąd i/lub naprawić?

Answer 1

Sprawdź linię 66 pliku SASS.

Sass::SyntaxError: Invalid CSS after "...ontent}*/ url(C": expected comma, was  
":/Program Files..."(sass):66 

Wygląda na nieprawidłowy błąd CSS. Zgaduję, że próbujesz połączyć się z zewnętrznym plikiem? Musisz sprawdzić ścieżki.

Prawdopodobnie nie można użyć „C:/Program Files ...”, zamiast zmienić go na relative path w odniesieniu do plików tj

url(../../external_directory/image.png) 

Answer 2

Upewnij się, że pliki CSS składnia jest prawidłowa i odpowiednio wcięte . Albo można odinstalować Sass gem gem z pliku ... ale nie jest to dobre rozwiązanie .. spróbować skorygować swoją składnię css ..

Answer 3

po wycofaniu wersji sprockets' from 3.2.0 to 2.12.3 , the error disappeared. The error seems to be caused by incompatible version of koła zębate, które czynią aktywa prekompilowanymi dla Railsów.

Answer 4

Procesor Sass (znajduje się w klejnot Sass) rzuca błąd składni przy napotkaniu następujący kod:

ontent}*/ url(C:/Program 

których kod jest generowany przez rurociąg aktywów gdy prekompilacja jednego ze swoich lokalnych aktywów kosztownych (większość prawdopodobnie gem jQuery UI-szyny, plików jQuery UI-szyn-xxx \ app \ aktywa \ javascripts \ jquery-ui \ theme.css.erb następujący wiersz):

background: #ffffff/*{bgColorContent}*/ url(<%= image_path("jquery-ui/ui-bg_flat_75_ffffff_40x100.png") %>) 

Jeśli trzeba zlokalizuj dokładną lokalizację błędu, którą możesz tymczasowo skomentować w następującej linii:

was = was[0...15] + "..." if was.size > 18 

w gem SaaS-x.x.x Sass \ lib \ Sass \ SCSS \ parser.rb pliku def self.expected (skaner oczekuje linia) Metoda.

Metoda pomocnicza image_path nie używa poprawnej ścieżki do zasobu, z powodu niepoprawnej wartości w config.relative_url_root (względne_url_root wydaje się być przestarzałe, ale nadal używane przez ścieżkę image_path). http://apidock.com/rails/ActionView/Helpers/AssetUrlHelper/asset_path

Inne klejnoty wykorzystujące Rails.application.config.action_controller.relative_url_root (jak ckeditor_rails) generują te same problemy podczas prekompilacja.

Problem powstaje podczas uruchamiania zadania prekompilacji (lub konsoli szyn) za pomocą parametru RAILS_RELATIVE_URL_ROOT. Run

RAILS_RELATIVE_URL_ROOT /yourapprelativeurl rails c 

i widać złą drogę z:

p Rails.application.config.action_controller.relative_url_root 

Jeden obejście jest ustawione w aplikacji.rb:

config.action_controller.relative_url_root = "" #or "yourapprelativeurl" 

Spowoduje to prekompilację zasobów klejnotów, ale może również przynieść inne nieoczekiwane rezultaty.
