我正在尝试使用 Heroku 部署一个 webapp，它已被部署，但当我尝试打开它时它会出现内部服务器错误。 heroku logs -t的完整日志如下：

我已经完成了此处给出的其他一些解决方案，但它们都使用 matplotlib 库，而我的不需要 matplotlib 并且我也没有在requirements.txt文件中提到它，但是它在部署时安装在 Z3115FB34DFCB568AA049707 我知道 heroku 不支持_tkinter 。 那么我还能做些什么让它正常运行呢？

python 版本：3.8.8

如果需要，我可以提供更多详细信息。

Answer 1

将我的 django 应用程序部署到 Heroku 时，我遇到了同样的错误。 我发现我在我的 models.py 文件中从 tkinter 导入 CASCADE。 我变了

from tkinder import CASCADE

至

from django.db.models.deletion import CASCADE

这解决了我的问题。

有时它并不总是在 models.py 文件中。 如果您遇到这种情况，请继续阅读错误消息，您最终会找到导入 tkinter 的文件。 我这样做了，并且在错误的底部发现了这个：

  File "/app/blog/views.py", line 1, in <module>
from turtle import home

所以我只需要删除我的 blog/views.py 文件中的第一行。 它奏效了！

所以在你的情况下，我认为问题显示在。

2021-10-29T09:03:55.451470+00:00 app[web.1]: File "/app/apis/model.py", line 9, in <module>
2021-10-29T09:03:55.451470+00:00 app[web.1]: import PySimpleGUI as sg

根据这个链接，PySimpleGUI 是一个包装 tkinter 的 python 库。 仅此一项就为我们提供了解决方案。 所以从你的 apis/model.py 中删除那个导入。

*确保您将更改提交到您的 git repo 并再次推送到 heroku。

Answer 2

我试图将应用程序部署到 Heroku 并收到此错误。

这个错误可能是因为在我们的代码中某处导入了 tkinter。 请正确检查并删除它。

Answer 3

不知道你是否还需要这个答案，但我遇到了同样的问题。 我通过删除项目中所有未使用的导入来修复它。 完成此操作并重新部署后，我能够解决此问题，希望对您有所帮助

Answer 4

几天前我遇到了同样的问题，我发现title是由 vs code 自动导入的。 仔细检查脚本上的所有导入。 某些东西可能是自动导入的。
