1 个解决方案

I'm also working with Django and saw this same exact error in heroku logs --tail a few minutes after I pushed updated to Heroku.我也在使用 Django，在我将更新推送到 Heroku 几分钟后，在heroku logs --tail 。 Prior to the push to Heroku everything worked just fine.在推送到 Heroku 之前，一切都运行良好。

To solve this problem, first I made sure that the following files that worked previously remain unchanged with the push:为了解决这个问题，首先我确保以下以前工作的文件在推送时保持不变：

requirements.txt要求.txt
Aptfile文件
Procfile简介
runtime运行
wsgi wsgi

Since these files remained unchanged, I concluded that something beyond my knowledge was causing issues.由于这些文件保持不变，我断定是我不了解的东西导致了问题。 So I went into the app's Activity Feed in Heroku, found the version that I knew worked and clicked on the Roll back to here link.所以我进入了应用程序在 Heroku 中的Activity Feed ，找到了我知道有效的版本并单击了Roll back to here链接。

When that didn't work, per the recommendation of another user (whose comment I can't seem to find now), I removed all packages from the requirements.txt then pushed it up to Heroku so that all packages would be uninstalled in the app.当这不起作用时，根据另一个用户的建议（我现在似乎找不到他的评论），我从requirements.txt中删除了所有包，然后将其推送到 Heroku，以便所有包都将在应用程序。 Then I added back all packages to the requirements.txt and pushed it to Heroku.然后我将所有包添加回requirements.txt并将其推送到 Heroku。 Now it works.现在可以了。
