Question

I’m trying to compile some .less files using django-pipeline. When I run collectstatic, everything copies over correctly, and then I get this error:

Traceback (most recent call last):

    i = p.rfind('/') + 1
AttributeError: 'NoneType' object has no attribute 'rfind'

I don’t think I’ve done anything weird with the types in my settings.py, but here’s the relevant bit of it just in case:

STATICFILES_STORAGE = "pipeline.storage.PipelineCachedStorage"

PIPELINE = True

STATICFILES_DIRS = (
    ("projectname", os.path.join(REPO_ROOT, "static")),
)

PIPELINE_COMPILERS = (
    'pipeline.compilers.coffee.CoffeeScriptCompiler',
    'pipeline.compilers.less.LessCompiler'
)

PIPELINE_JS = {
    'projectname': {
        'source_filenames': ('js/*.coffee',),
        'output_filename': 'projectname/js.js'
    }
}

PIPELINE_CSS = {
    'projectname': {
        'source_filenames': ('css/style.less',),
        'output_filename': 'projectname/css.css'
    }
}

If I replace my CSS source_filenames with a glob (ie css/*.less) I get the same result. The file is definitely where I’m telling it it is (at the very least, if I replace it with a path that I know is wrong, I get a different error). With the PIPELINE_CSS lines commented out, my CoffeeScript compiles to JS just fine. Any ideas?

Can you try running this :


$ python manage.py findstatic css/style.less


If you have this result :


No matching file found for 'css/style.less'.


You’re likely misconfigured staticfiles, otherwise let me know too.
