！ [远程拒绝] master -> master (pre-receive hook denied) 错误：未能将一些参考推送到“https://git.heroku.com/stark-dawn-54447.git”

Question

我是 Django / Python 新手，正在尝试将我的第一个项目部署到 Heroku。我收到以下错误，并且一直在遵循这封信指南：William S Vincent 的“初学者 Django”。

当我运行时：$git push heroku master

我明白了：

错误：！ [remote denied] master -> master (pre-receive hook denied) 错误：未能将一些参考推送到“https://git.heroku.com/stark-dawn-54447.git”

我已经包含了下面返回的所有代码...

非常感谢

是的，这是 Pipenv 的问题，看起来它使用了一个没有被正确处理的生成器。

要解决此问题，您可以将 Pipenv 版本从 2018.5.18 升级到当前版本，即 2020.6.2 从 PyPI。
