问题描述
在这里可能有点儿深入，我已经阅读了heroku文档，但仍然不太了解应该如何设置Procfile.尝试部署heroku($ heroku open)，显示以下错误日志:
possibly a little out my depth here, I've read the heroku docs thoroughly and still don't quite understand how the Procfile should be set up. Trying to deploy heroku ($ heroku open), gives this error log:

我想这是大量令人困惑的代码2020-01-27T11:39:57.599554+00:00 app[web.1]: ModuleNotFoundError: No module named 'grad'的有效方法，但我显然不是专家...
I guess that this is the operative line in that mass of confusing code 2020-01-27T11:39:57.599554+00:00 app[web.1]: ModuleNotFoundError: No module named 'grad', but I'm quite obviously no expert...
我的Procfile看起来像这样:
My Procfile looks like this:
web: gunicorn grad.wsgi:application --log-file - --log-level debug --preload --workers 1
grad.wsgi看起来像这样:
grad.wsgi looks like this:
import os
from django.core.wsgi import get_wsgi_application
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "grad.settings")
application = get_wsgi_application()

I can't think what else might be needed but please request any further info. Any clear and idiot-proof advice on how Procfile works would be great, thanks in advance.
推荐答案
您正确地识别出错误消息中的关键行是ModuleNotFoundError.
You correctly identified that the key line in the error message is the ModuleNotFoundError.
2020-01-27T11:39:57.599554+00:00 app[web.1]: ModuleNotFoundError: No module named 'grad'
问题是您的Django项目目录(包含manage.py的目录)不在项目根目录中，而是在gpproject目录中.
The problem is that your Django project directory (the one containing manage.py) isn't in the project root, it's in the gpproject directory.
因此，您需要使用--python标志将该目录添加到Python路径中，以便可以导入其中的grad模块.
Therefore you need to add that directory to the Python path with the --python flag, so that the grad module inside it can be imported.
web: gunicorn grad.wsgi:application --python gpproject --log-file - --log-level debug --preload --workers 1
