我的procfile
"web: gunicorn ecommerce2.wsgi"
我的wsgi.py
import os
from django.core.wsgi import get_wsgi_application
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "ecommerce2.settings")
application = get_wsgi_application()
和与H14有关的文档错误可以通过 heroku ps：scale web = 1 修复，然后弹出
Scaling dynos... !
! Couldn't find that process type.
即使我成功添加了Procfile，当我查看Heroku帐户时，资源中的Dynos仍在说以下tex。
This app has no process types yet
Add a Procfile to your app in order to define its process types. Learn more
如何解决此问题？ 谢谢你的帮助。

上次出现此问题与找不到要求有关。从本地更新您的requirements.txt文件。
您还想在settings.py
DEBUG = False
DEBUG_PROPAGATE_EXCEPTIONS = True
添加这些生产线。这将错误记录。在那里，您可以看到为什么出现应用程序错误。
（我愿意打赌它缺少一些包裹。让我知道它是什么。）
答案 1 :(得分：0)
今天，我遇到了同样的错误。在我的根目录中，我具有没有任何扩展名的Procfile，但是当我在Visual Studio代码中打开代码时，Procfile的扩展名为.txt，并显示为“ Procfile.txt”。我只是从文件中删除了.txt并保存了它。这解决了我的错误。
您可以参考我的帖子进行更多说明：
