启用 WhiteNoise 时“collectstatic”命令失败

我正在尝试通过以下方式提供静态文件白噪声 https://github.com/evansd/whitenoise/blob/master/docs/django.rst as per Heroku https://devcenter.heroku.com/articles/django-assets的推荐。当我跑步时collectstatic在我的开发环境中，会发生这种情况：

Post-processing 'css/iconic/open-iconic-bootstrap.css' failed!

当我在设置中注释掉这一行时，静态收集命令运行时不会发生任何事件：

STATICFILES_STORAGE = 'whitenoise.django.GzipManifestStaticFilesStorage'

这里出了什么问题以及如何修复它？我已经尝试清空静态文件输出文件夹。它运行平稳，直到开始处理一个特定文件。

我刚刚遇到了同样的问题，并通过从我的设置文件中删除这一行来修复它，

STATICFILES_STORAGE = 'whitenoise.django.GzipManifestStaticFilesStorage'

我从 Heroku 文档页面得到了这一行......
