Python PipelineStorage IOError:[Errno 21]

我开始使用Django，我想要一个SASS编译器，所以我找到了Django管道。我遵循了教程中的步骤，并设法进入了静态步骤。当我运行命令时

manage.py collectstatic

然后键入“是”，我会收到以下错误： （全部回溯）

我也安装了Yuglify。当此行位于settings.py中时会发生错误：

STATICFILES_STORAGE = 'pipeline.storage.PipelineStorage'

删除它我没有收到任何错误，所有文件都被复制到静态根目录，但不知何故，我觉得这一行很重要，应该省略
