我正在尝试在Heroku上部署我的应用程序。它之前已成功上传，但是我进行了一些更改，并尝试重新上传，但此后一直未响应。我一直收到此错误： whitenoise.storage.MissingFileError：无法找到文件'ecommerce / fonts / icofont.eot'。我该怎么办？

这是回溯：

whitenoise.storage.MissingFileError: The file 'ecommerce/fonts/icofont.eot' could not be found with <whitenoise.storage.CompressedManifestStaticfilesStorage object at 0x7f73c4861320>.
remote:        The CSS file 'ecommerce/css/icofont.css' references a file which could not be found:

我的settings.py文件中有这个

STATIC_ROOT = os.path.join(BASE_DIR,'staticfiles')
STATIcfileS_STORAGE = 'whitenoise.storage.CompressedManifestStaticfilesStorage'
STATIC_URL = '/static/'
