[英]Django app on heroku, ModuleNotFoundError: No module named 'spread'
我正在努力在 heroku 上运行我的应用程序。 在本地机器上一切正常。 Ive deployed a django app to heroku with no issues ( git push heroku master is working properly) however whenever I am trying to heroku open heroku logs are pointing out an error ModuleNotFoundError: No module named 'spread'
我研究了大多数与 stackoverflow 相关的问题和谷歌文章和教程，但没有成功。 我希望这只是一些我无法弄清楚的简单问题。 任何帮助将不胜感激。 谢谢
heroku 日志 --tail错误出现在底部
