Perché `middleman serve` funziona, ma` middleman build` non riesce a compilare questo Sass?

Question

Quando ho appena eseguito middleman per servire, all.css viene compilato bene, che consiste di solo una chiamata a +box-shadow(none):

/* line 1, /home/yang/asdf/source/stylesheets/content.css.sass */ 
div { 
    -webkit-box-shadow: none; 
    -moz-box-shadow: none; 
    box-shadow: none; } 

Ma quando ho costruire il sito, ottengo questo errore Sass/Compass:

$ middleman build 
Slim::EmbeddedEngine is deprecated, it is called Slim::Embedded in Slim 2.0 
Slim::EmbeddedEngine is deprecated, it is called Slim::Embedded in Slim 2.0

Ho riprodotto questo nel seguente piccolo esempio semplice, che ho anche incluso come tar.gz codificato in base64 nella parte inferiore se si desidera eseguire la repro localmente. Include anche il backtrace completo.

Ecco l'albero di file:

asdf 
├── config.rb 
├── config.ru 
├── error 
├── Gemfile 
├── Gemfile.lock 
├── source 
│   └── stylesheets 
│    ├── all.css.sass 
│    └── content.css.sass 

Ecco tutti i contenuti di file:

config.rb:

require 'animate-sass' 
require 'susy' 
require 'slim' 
set :css_dir, 'stylesheets' 
set :js_dir, 'javascripts' 
set :images_dir, 'images' 
set :fonts_dir, 'fonts' 
configure :build do 
    activate :minify_css 
    activate :minify_javascript 
    activate :relative_assets 
    require "middleman-smusher" 
    activate :smusher 

config.ru:

require 'rubygems' 
require 'middleman/rack' 
run Middleman.server 

Gemfile:

source :rubygems 
gem "slim" 
gem "susy" 
gem "animate-sass" 
gem "middleman", "~>3.0.13"

Gemfile.lock: vedi tar.gz

all.css.sass:

@import compass/css3/box-shadow 
@import content 

content.css.sass:

div 
    +box-shadow(none) 

Ecco la base64 encodede tar.gz, che puoi decodificare con base64 -d:

Grazie in anticipo per qualsiasi aiuto!

Answer 1

Ciò si è verificato a causa di alcuni file che non devono essere emessi con nomi che non iniziano con un carattere di sottolineatura. Ad esempio, content.css.sass dovrebbe essere _content.css.sass, in modo che middleman sappia che non provare a creare direttamente quel file. (Non abbiamo familiarità con middleman ecc. - questo era un pacchetto consegnato a noi, quindi ci è voluto un po 'per rintracciarlo.)

Answer 2

Quindi mi sono imbattuto in questo e volevo dare una risposta più precisa:

Qualsiasi file @import nella catena downstream da un file con nome non sottolineato verrà interrotto con un errore come Sass::SyntaxErrorUndefined Variable o Undefined mixin.

È semplice come assicurarsi che ogni file nella catena inizi con un trattino basso; a volte molto facile da passare!
