尝试启动 heroku 应用程序时出现 H10 错误
H10 error when trying to start heroku app
我正在尝试使用 python flask 应用程序启动我的 heroku 应用程序，但我收到 h10 错误，我在日志中唯一能看到的是找不到 Tkinter，但我没有使用Tkinter 在这个项目中请帮助。我一直在网上和其他堆栈溢出问题上搜索，但大多数人只是说要确保您没有声明端口或某些 js 服务器。我没有找到任何有用的东西，当我阅读日志时，我看到的只是 Tkinter，但我试图从我的代码中清除它，但它仍然试图调用它。

当前问题是由以下导入引起的：
from turtle import back
在 Web 应用程序中使用 the turtle module 没有多大意义。幸运的是，你似乎并没有真正使用它。
删除该行，提交并重新部署。
完成后，您可能会发现您的 SQLite 数据库 doesn't behave as you expect it to。
Heroku 的 ephemeral filesystem makes file-based databases like SQLite a poor choice. A client-server database like PostgreSQL will work much better. Heroku's own Postgres service 可能是一个不错的起点。
我正在尝试使用 python flask 应用程序启动我的 heroku 应用程序，但我收到 h10 错误，我在日志中唯一能看到的是找不到 Tkinter，但我没有使用Tkinter 在这个项目中请帮助。我一直在网上和其他堆栈溢出问题上搜索，但大多数人只是说要确保您没有声明端口或某些 js 服务器。我没有找到任何有用的东西，当我阅读日志时，我看到的只是 Tkinter，但我试图从我的代码中清除它，但它仍然试图调用它。

当前问题是由以下导入引起的：
from turtle import back
在 Web 应用程序中使用 the turtle module 没有多大意义。幸运的是，你似乎并没有真正使用它。
删除该行，提交并重新部署。
完成后，您可能会发现您的 SQLite 数据库 doesn't behave as you expect it to。
