Я пытаюсь скомпилировать некоторые .less файлы с использованием django-pipeline. Когда я бегу collectstatic, все копируется правильно, а потом я получаю эту ошибку:

Я не думаю, что сделал что-то странное с типами в моем settings.py, но вот соответствующий фрагмент на всякий случай:

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'
    }
}

Если я заменю свой CSS source_filenames с шариком (т.е. css/*.less) У меня тот же результат. Файл определенно находится там, где я говорю (по крайней мере, если я заменю его на путь, который, как я знаю, неверен, я получу другую ошибку). С PIPELINE_CSS строки закомментированы, мой CoffeeScript отлично компилируется в JS. Любые идеи?

Мой код выдает исключение, но поиск в Google мне не помог. Я проверил ошибку, возможно, он получил неправильный путь, но он выводит правильный путь на консоль.

Exception Value:

‘NoneType’ object has no attribute ‘rfind’

def user_directory_path(instance, filename):
    time_stamp = 'user_{0}/{1}'.format(instance.user, filename)
    createfolder = os.path.join('home', 'ttt', 'Desktop', 'GolemProject', 'Fileuploads', time_stamp,)
    print(createfolder)
    if not os.path.exists(createfolder):
        os.makedirs(createfolder)

Я пытаюсь определить расширение файла, используя os.path.splitext

вот мой код:

    m = email.message_from_string(s[0][1])
    result = re.findall(pattern,str)

        for part in m.walk():
            filename = part.get_filename()
            if filename:
                extension = os.path.splitext(fileName)
                if extension[1][1:] == 'csv':      
                    ### Process into a dataframe
                    df = pd.read_csv(StringIO(filename))

здесь приведено сообщение об ошибке с IPython:

NoneType должен означать, что я ничего не пропускаю, когда печатаю тип (имя файла), я получаю:

как передать файл, чтобы определить расширение, а затем создать dataframe? мне нужно сохранить на диск

это будет для синтаксического анализа script, который регулярно рассылается по электронной почте csv’ed, поэтому регулярное выражение определяет, какое правило следует следовать.
