如何修复Heroku的H10错误？

Question

我试图推出一个简单的投资组合网站使用Heroku，但每次我运行的应用程序，我得到了H10的错误。我能做些什么来修复它？你知道吗

在整个过程中，我遇到了各种各样的错误，我已经设法解决了。但是最近的这个错误，H10，我似乎不知道发生了什么。在日志中，我可以看到应用程序要求我为17个文件应用迁移。我运行python manage.py migration，它说没有什么要更新的。然后我尝试进行heroku run python manage.py迁移，它成功地运行了。你知道吗

然后，我做git add .，git commit -m "comment"，最后是git push heroku master。这就是它运行时发生的情况。你知道吗

我运行git logs来看看到底发生了什么，我得到了以下结果：
