使用 Heroku/Flask Server 部署网站时出错

Question

我正在尝试使用 Flask/SQLAlchemy 部署一个网站，以使用女服务员托管我的数据库。我确实尝试关注此链接，但我认为我的文件结构不一样 Heroku + node.js error (Web process failed to bind to $PORT within 60 seconds of launch)

这是我的文件结构

Server
->BarBeerDrinker
 ->__pycache__
 ->static
 ->__init__.py
 ->configt.py
 ->database.py
->app.py
->Procfile
->requirements.txt

尝试访问我的网站后，我在控制台中输入heroku log --tail，这就是我得到的。

我对尝试部署网站非常陌生，老实说，我只是按照我的教授在这里给我们的基本指导进行操作 https://drive.google.com/file/d/1dltcKrigTvtJk3hHvl7I_y0KnlGuy3V9/view?usp=sharing

Answer 1

PermissionError 表示您可能需要授予文件可执行权限。尝试向runner.py 和/或server.py 授予权限。

chmod 777 /path/to/runner.py
chmod 777 /path/to/server.py

777 将授予所有者/组/其他广泛的读/写/执行权限。你可能想要更具体的东西，比如chmod 755 path/to/file.py。请参阅 chmod here 的手册页。
