Cant compress files with django-pipeline and YUI

Question

When I run python manage.py collectstatic, I get:

Traceback (most recent call last):

ValueError: The file 'css/960_24_col.css' could not be found with <pipeline.storage.PipelineFinderStorage object at 0x101da4d50>.

When I run python manage.py findstatic css/960_24_col.css, I get

Found 'css/960_24_col.css' here:
  /Users/fceruti/Development/xxxxxxx/Arriendas/static/css/960_24_col.css

My settings are:

STATIC_ROOT = os.path.join(PROJECT_ROOT, 'static')

STATICFILES_DIRS = (
    ('css', os.path.join(STATIC_ROOT, 'css')),
    ('img', os.path.join(STATIC_ROOT, 'img')),
    ('js', os.path.join(STATIC_ROOT, 'js')),
    ('fonts', os.path.join(STATIC_ROOT, 'fonts')),
)

STATICFILES_FINDERS = (
    'django.contrib.staticfiles.finders.FileSystemFinder',
    'django.contrib.staticfiles.finders.AppDirectoriesFinder',
    'django.contrib.staticfiles.finders.DefaultStorageFinder',
)
PIPELINE = True
PIPELINE_CSS = {
    'app': {
        'source_filenames': (
            'css/960_24_col.css',
            'css/base.scss',
        ),
        'output_filename': 'css/app.css',
        'extra_context': {
            'media': 'screen,projection',
        },
    },
}
PIPELINE_CSS_COMPRESSOR = 'pipeline.compressors.yui.YUICompressor'
PIPELINE_JS_COMPRESSOR = 'pipeline.compressors.yui.YUICompressor'
PIPELINE_YUI_CSS_ARGUMENTS = ''
PIPELINE_YUI_JS_ARGUMENTS = ''
PIPELINE_YUI_BINARY = os.path.join(PROJECT_ROOT, 'libs/yuicompressor-2.4.7/build/yuicompressor-2.4.7.jar')

STATICFILES_STORAGE = 'pipeline.storage.PipelineCachedStorage'
PIPELINE_SASS_BINARY = '/usr/bin/sass'

When I add

PIPELINE_COMPILERS = (
    'pipeline.compilers.sass.SASSCompiler',
)

And run the webpage, I get:

Exception Type: CompilerError
Exception Value:    
Unable to apply SASSCompiler compiler

What am I doing wrong?

EDIT:

The softwares I'm using are:

• Sass 3.1.19 (Brainy Betty)
• YUI compressor 2.4.7
• django-pipeline==1.2.11
• Django 1.4

Answer 1

First, You should not put the jar as PIPELINE_YUI_BINARY, but you should point to a script that call the jar with java (most of the time, it's bundle with it when packaged). It looks like this :

#!/bin/sh
java -jar "/path/to/yuicompressor-2.4.7.jar" $@

Answer 2

I think you want your STATICFILES_DIRS to look something like this:

STATICFILES_DIRS = ('./static/')

If that doesn't work, try something like this.

PROJECT_ROOT = os.path.abspath(os.path.dirname(__file__)[0: (os.path.dirname(__file__).rindex(os.sep + 'src' + os.sep))])
STATICFILES_DIRS = (os.path.join(PROJECT_ROOT, 'static/' ))

(the idea is to set PROJECT_ROOT to the top level directory for your app)

The way you have it set up it will look in each of your sub directories for "css/960_24_col.css" In other words it will look for

• STATIC_ROOT/css/css/960_24_col.css
• STATIC_ROOT/img/css/960_24_col.css
• STATIC_ROOT/js/css/960_24_col.css
• STATIC_ROOT/fonts/css/960_24_col.css

And it won't find it, because the file is at

STATIC_ROOT/css/960_24_col.css

---

In general, STATICFILES_DIRS is a collection of /static/ directories that are contained in different apps. If yourApp includes myApp, and myApp has a static directory you'd put both yourApp's static dir and myApps static dir on the list. Collectstatic will combine them into STATIC_ROOT and then run Pipeline on that.
