正在获取 python3: 无法打开文件 'daphne': [Errno 2] Heroku 中没有这样的文件或目录（requirements.txt 中有 daphne）
Getting python3: can't open file 'daphne': [Errno 2] No such file or directory in Heroku (requirements.txt has daphne in it)
这是我的 requirements.txt:
fastapi
pydantic
daphne
这是 Procfile：
web: python3 daphne -b 0.0.0.0 -p 8000 main:app
这是日志：

将其放入文件 app.py:
from daphne.cli import CommandLineInterface
CommandLineInterface.entrypoint()
使用 python3 app.py -b 0.0.0.0 -p 8000 main:app
进行测试
然后将其放入 Procfile:
web: python3 app.py -b 0.0.0.0 -p 8000 main:app
不工作
无法正常工作，因为 __main__ 不解析命令行，并且 heroku local 不支持 -m 开关 (?)。
您想执行一个模块，而不是一个文件。达芙妮是模块。所以试试
web: python3 -m daphne -b 0.0.0.0 -p 8000 main:app
这是我的 requirements.txt:
fastapi
pydantic
daphne
