Django collectstatic not working with django-pipeline and yui-compressor

Question

I've installed django-pipeline on my Django 1.4.1 application under a virtualenv but when I run python manage.py collectstatic, I get:

Traceback (most recent call last):

My settings are:

# static
STATIC_ROOT = join(REPOSITORY_ROOT, 'static_collected')
STATIC_URL = '/static/'
STATICFILES_DIRS = (join(REPOSITORY_ROOT, 'static'),)
STATICFILES_FINDERS = (
    'django.contrib.staticfiles.finders.FileSystemFinder',
    'django.contrib.staticfiles.finders.AppDirectoriesFinder',
)

# pipeline (css/js compression)
STATICFILES_STORAGE = 'pipeline.storage.PipelineCachedStorage'
PIPELINE = True
PIPELINE_CSS = {
    'base_style': {
        'source_filenames': (
            'css/style.css',
            'css/effects.css',
            'css/rs_style.css',
            'css/jq/jquery-ui-movieplayer.css',
        ),
        'output_filename': 'CACHE/css/style.css',
    },
}

PIPELINE_JS = {
    'base_scripts': {
        'source_filenames': (
          'js/jq/jquery.js',
          'js/mv.core.js',
          'js/toolbox/toolbox.core.js',
          'js/swfobject.js',
          'swf/jwplayer5.9.2156.js',
          'js/jq/jquery-ui.custom.min.js',
          'js/mongo_autocomplete.js',
          'js/rs_script.js',
        ),
        'output_filename': 'CACHE/js/scripts.js',
    }
}

Before adding django-pipeline the management command worked well, it found everything, so it's not an issue related to finding the static files nor to directory permissions. The Yuicompressor is installed globally and can be found under /usr/local/bin/yuicompressor so I didn't modify PIPELINE_YUI_BINARY in my settings.

Any clue? Thank you!

Answer 1

IOError: [Errno 32] Broken pipe

This error means that yuicompressor has quit before we had time to send data (most of the time because it crashed or because it wasn't found). Check your yuicompressor path, and check if yuicompressor actually works.

Answer 2

Add paths to the executables in the setting, e.g.

PIPELINE_YUI_BINARY = '/usr/bin/yui-compressor'
PIPELINE_LESS_BINARY = '/usr/local/lib/node_modules/less/bin/lessc' 

Paths may differ(especially for lessc, in this example less was installed with "npm install -g less")
