CS50 Ide 烧瓶缓慢且错误

Question

我已经完成了我的最终项目，一个游戏网站之类的东西，我用 flask 做的。我大约 2 个月前完成了这个项目，直到现在我才提交它，但是当我开始制作 video 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，而其他页面则需要很长时间，所以我删除了“flask_sessions”中的所有文件如果我删除它们，会话不会影响整个程序。它有效，但我无法进入我以前无法进入的页面。我在运行我的烧瓶应用程序的终端中遇到了这些错误。

Traceback (most recent call last):
File "/usr/local/lib/python3.9/site-packages/cachelib/file.py", line 162, in get
with open(filename, "rb") as f:

感谢任何帮助，谢谢！

** 21 年 8 月 18 日更新：今天再次运行我的代码，我不再收到警告错误。我还意识到我的代码中有一个错误导致链接无法正常工作！可能值得重新运行调整您的代码并查看警告消息是否也适用于您。**

*我仍然在掌握一些东西（因此在 CS50 课程上！）如果这不是那么有用，我深表歉意。但我也有一个非常相似的问题——我在大约一个月的休息后回来拍摄我的最终项目视频，现在无法访问我网站的一半，因为我的商店页面上的链接不再加载页面。我收到了一条与你自己类似的错误消息：

我注意到 Python 的新版本（Python 3.9.6）最近被安装到 IDE，想知道这是否会导致某处链中断为了我们？但我似乎无法在 google 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。我会继续谷歌搜索，如果你碰巧弄明白了，我会很感激你的决定！杰斯*
