我是 pyhton 的新手，我試圖在 Heroku（部署日志）上部署我的簡單應用程式，但我得到了錯誤：
應用程式錯誤 應用程式發生錯誤，無法提供您的頁面。如果您是應用程式所有者，請查看您的日志以獲取詳細資訊。您可以從 Heroku CLI 使用命令 heroku logs --tail 執行此操作

部署日志沒問題，但我找不到可能的問題（對不起這個愚蠢的問題）。

我的檔案系統沒有 config.toml，在 flher .streamlit/ 中有 2 個檔案 .stable_random_id 和憑據（我洗掉的最后一個）。我嘗試自己創建 config.toml 但無論如何都沒有作業。我在 config.toml 中使用了這個：
mkdir -p ~/.streamlit/
echo "\
[server]\n\
port = $PORT\n\
enableCORS = false\n\
headless = true\n\
\n\
" > ~/.streamlit/config.toml
@ferdy 這里是 heroku 的日志錯誤資訊：

uj5u.com熱心網友回復：
僅基于此處的示例，您似乎已將其系結到具有已知安全問題的 python 版本，否則我在此處的示例中看不到任何錯誤。如果您將您的要求更新到 3.8.13，它應該會消除該錯誤，因為 3.8.12 中有 85 個漏洞。

我可以使用您的代碼在 heroku 中成功部署。
