django1.9,從github下載xadmin源文件后，跟著視頻配置，然后就出現(xiàn)這個錯誤。RuntimeError: Model class extra_apps.xadmin.models.Bookmark doesn't declare an explicit app_label and either isn't in an application in INSTALLED_APPS or else was imported before its application was loaded. （翻譯：RuntimeError：模型類extra_apps.xadmin.models.Bookmark沒有聲明顯式app_label，也不在INSTALLED_APPS中的應(yīng)用程序中，或者在加載應(yīng)用程序之前導(dǎo)入。）
請問django xadmin RuntimeError錯誤 的問題？
