面对ModuleNotFoundError：没有名为“ blog_project.wsgi”的模块

• 问答

我正在尝试在heroku上部署django应用程序。构建成功，但是当我启动应用程序时，遇到导入错误。 “没有名为'blog_project.wsgi'的模块”。该应用程序在本地环境上运行良好。

以下是/blog/blog_project/blog_project/wsgi.py文件的内容

import os
import sys

from django.core.wsgi import get_wsgi_application

path = "/home/ashish/Documents/Django/blog/blog_project/"
if path not in sys.path:
    sys.path.insert(0,path)

os.environ['DJANGO_SETTINGS_MODULE'] = 'blog_project.settings'

application = get_wsgi_application()

该怎么办？ 预先感谢。

ww8q2008 回答：面对ModuleNotFoundError：没有名为“ blog_project.wsgi”的模块
CREATE TABLE `game_info`

这告诉我您的Procfile看起来像这样：

2020-03-23T02:48:46.264529+00:00 heroku[web.1]: Starting process with command `gunicorn blog_project.wsgi --log-file -`

在根目录中没有名称为web: gunicorn blog_project.wsgi --log-file - 且文件结尾为blog_project的文件。

应该是这样的：

.wsgi

您可能希望将代码包装在根目录的web: gunicorn blog_project/blog_project/wsgi:app 中，以便执行以下操作：

main.py
