无法在Heroku上部署Django

Question

我在本地主机上有一个名为“django_项目”的项目；正在运行。
现在，我已经尝试在Heroku部署我的应用程序（真的尝试了一切），但出现了错误：

heroku[web.1]: Starting process with command `gunicorn django_projcet.wsgi  
heroku[web.1]: State changed from starting to crashed  
heroku[web.1]: Process exited with status 3   
app[web.1]: ModuleNotFoundError: No module named 'django_projcet'      
app[web.1]: [INFO] Worker exiting (pid: 10)     
app[web.1]: [INFO] Shutting down: Master      
app[web.1]: [4] [INFO] Reason: Worker failed to boot.

我的项目树：

程序文件：

web: gunicorn django_projcet.wsgi

Wsgi.py：

"""
WSGI config for django_project project.

It exposes the WSGI callable as a module-level variable named ``application``.

For more information on this file, see

"""

import os

from django.core.wsgi import get_wsgi_application

os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'django_project.settings')

application = get_wsgi_application()

Answer 1

要在Heroku中部署django应用程序，您需要3个文件

1. runtime.txt
2. 程序文件
3. requirements.txt

在runtime.txt中提及您的python版本

python-3.7.8

在程序文件中

web: gunicorn django_project.wsgi

对于requirements.txt，您可以使用

pip freeze > requirements.txt

There is a mistake in your Procfile, You wrote web: gunicorn django_projcet.wsgi

Change to web: gunicorn django_project.wsgi

your project name does not match as in Procfile
