Heroku-第一行出现code =“ H10”错误

Question

因此，我尝试在线建立我的网站，并且它显示“构建成功”，但是当我尝试进入该网站时，出现此错误：

所以我在终端中输入了命令，然后我的服务器出现了这个错误：

File "/app/Server.py", line 1, in <module>
import requests

requests包含在requirements.txt中，我不确定为什么会收到此错误 Procfile：

web: gunicorn --bind 127.0.0.1:5000 Server:app

我正在使用python，flask，Server.py是文件名，app = Flask(__name__)

完整日志错误：

Answer 1

所以第一个问题是我需要将所有模块安装到Pipfile（项目中的所有模块）。由于某种原因，如果您坚持要知道为什么它不起作用，请尝试阅读A question about it（可能需要重新修改），以确保我的requirements.txt没有通过。第二个问题就在我的头上：我将程序放在def main()中，因为@mechanical_meat说“应用程序必须在模块的顶层可用”，您不能这样做。
