Have you gone through the Heroku guide for setting up a Django application? What does your Procfile look like?

Your project should have a file named Procfilethat should have contents similar to
您的项目应该有一个名为的文件Procfile，该文件的内容类似于
web: gunicorn hellodjango.wsgi

Benjamin Manns' solution worked for me, though I needed one additional step as well.
Benjamin Manns 的解决方案对我有用，但我还需要一个额外的步骤。
According to this, after the Procfilesolution has been pushed, run the following:
根据此，在之后Procfile的解决方案已被推，运行以下命令：
heroku ps:scale web=1
heroku ps:scale web=1
website should load correctly now.
网站现在应该可以正确加载。

If you are in python/django
如果你在 python/django
heroku logs --tail
if you are unable to find the bug and fix then try doing,
如果您无法找到错误并修复，请尝试执行，
First Run to see whether its working in herokus local
首先运行看看它是否在herokus本地工作
heroku local web
Mine was to specify the path of django wsgi.py file in Procfile
我的是在Procfile中指定django wsgi.py文件的路径
see their example https://github.com/heroku/python-getting-started
看他们的例子https://github.com/heroku/python-getting-started
The Procfile will look similar to this
Procfile 将与此类似
web: gunicorn projectname.wsgi --log-file -
You may have to install gunicorn if not installed and add it to requirements.txt
如果未安装，您可能需要安装 gunicorn 并将其添加到 requirements.txt
Then Git add and commit, after that push to heroku
然后 Git 添加并提交，然后推送到 heroku
git push heroku master
Then scale your app
然后扩展您的应用程序
heroku ps:scale web=1

I did the following steps to make it work.
我做了以下步骤来使它工作。
1) I had to move my Procfile to the outermost folder.
1）我不得不将我的 Procfile 移动到最外面的文件夹。
2) Then I had to change my Procfile to
2）然后我不得不将我的 Procfile 更改为
web: gunicorn projectname.projectname.wsgi
3) Also in my wsgi file I had to change my settings path to
3) 同样在我的 wsgi 文件中，我必须将设置路径更改为
os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'projectname.projectname.settings')
4) In my settings.py file I had to change my ROOT_URLCONF
4) 在我的 settings.py 文件中，我必须更改我的 ROOT_URLCONF
ROOT_URLCONF = 'projectname.projectname.urls'
5) In urls.py I had to change my path to
5) 在 urls.py 中，我必须将路径更改为
from projectname.applicationname import urls as app_urls
urlpatterns = [
path('admin/', admin.site.urls),
path('', include(app_urls)),
]
6) Finally I did
6）最后我做到了
git push heroku master
heroku ps:scale web=1
After making all these changes heroku worked like a charm. But it doesn't work locally on windows because I read somewhere windows doesn't have gunicorn.
完成所有这些更改后，heroku 工作起来很有吸引力。但它不能在 Windows 本地工作，因为我在某个地方读到 Windows 没有 gunicorn。
When I tried python projectname/manage.py runserverlocally it said
当我python projectname/manage.py runserver在本地尝试时，它说
ModuleNotFoundError: No module named 'projectname.projectname'
So for running it locally I've to revert all the steps above :P
所以为了在本地运行它，我必须恢复上面的所有步骤：P
