ValueError：使用collectstatic django时不允许空键名答案

【问题标题】：ValueError: Empty key names are not allowed when using collectstatic djangoValueError：使用collectstatic django时不允许空键名

【问题描述】：

我正在使用 django-pipeline S3PipelineManifestStorage 和 django-storages

当我使用 collectstatic 上传和后处理（缩小）我的资产时，后处理时出现错误。

之前，collectstatic 工作正常，没有报错。

这是完整的追溯

您能否弄清楚为什么会发生此错误？

【解决方案1】：

这是管道设置的问题 PIPELINE_CSS ={ 'maths_landing_page':{ 'source_filenames':( 'html/css/maths-landing-page.css' ), 'output_filename':'html/css/maths-landing-page-consolidated.css', } }

虽然实际设置是 PIPELINE_CSS ={ 'maths_landing_page':{ 'source_filenames':( 'html/css/maths-landing-page.css', ), 'output_filename':'html/css/maths-landing-page-consolidated.css', } }

注意元组中的逗号。

显然。

>>> type( ('a') )
<type 'str'>

>>> type( ('a',) )
<type 'tuple'>
