在这里可能有点儿深入，我已经彻底阅读了heroku文档，但仍然不太了解应该如何设置Procfile。尝试部署heroku（$ heroku open）时，显示以下错误日志：

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...
我的Procfile看起来像这样：
web: gunicorn grad.wsgi:application --log-file - --log-level debug --preload --workers 1
grad.wsgi看起来像这样：
import os
from django.core.wsgi import get_wsgi_application
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "grad.settings")
application = get_wsgi_application()

答案 0 :(得分：4)
您正确地确定错误消息中的关键行是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。
因此，您需要使用--python标志将该目录添加到Python路径，以便可以导入其中的grad模块。
web: gunicorn grad.wsgi:application --python gpproject --log-file - --log-level debug --preload --workers 1
答案 1 :(得分：0)
尝试将您的Procfile更新为：
const setup = (props = {}, state = null,initialState={}) => {
const store = storeFactory(initialState);
const wrapper = mount(
<Router
<Component {...props} store={store}/>
</Router>
);
if (state) wrapper.setState(state);
return wrapper;
};
我有一些使用类似设置的Heroku-Django应用程序。让我知道它是否适合您？
