CS50 Ide 烧瓶速度慢和错误

Question

我已经完成了我的最后一个项目，一个游戏网站之类的东西，我使用了flask。我大约 2 个月前完成了这个项目，直到现在才提交，但当我开始制作视频时，我意识到我的网站非常慢。 （我一直在使用cs50 ide）并且特定页面无法加载并且其他页面需要很长时间，所以我删除了“flask_sessions”中的所有文件，因为会话不会影响整个程序，如果我删除它们。它有效，但我无法访问以前无法访问的页面。我在运行烧瓶应用程序的终端中遇到了这些错误。

Traceback (most recent call last):

感谢任何帮助！

** 更新 18.08.21：今天再次运行我的代码后，我不再收到警告错误。我也意识到我的代码中有一个错误导致链接不起作用！可能值得重新运行您的代码并查看警告消息是否也为您消失了。**

*我仍然在处理事情（因此在 CS50 课程上！），如果这不是那么有帮助，我深表歉意。但我也有一个非常相似的问题——我在休息大约一个月后回来拍摄我的最终项目视频，现在由于我的商店页面上的链接不再加载页面，我无法访问我网站的一半。我也收到了类似的错误信息：

我注意到最近在 IDE 中安装了新版本的 Python（Python 3.9.6），并想知道这是否会导致我们在某个地方的链中断？但我似乎无法在谷歌上找到这方面的迹象。认为值得分享的是您的问题可能不是孤立的。我会继续搜索，如果你碰巧弄明白了，我会感谢你的解决方案！ 杰斯*
