【问题描述】：

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，我遇到了导入错误。 “没有名为‘blog_project.wsgi’的模块”。该应用程序在本地环境中运行良好。

if path not in sys.path:
    sys.path.insert(0, path)

application = get_wsgi_application()

怎么办？提前致谢。

【问题讨论】：

标签： django python-3.x heroku gunicorn django-wsgi

【解决方案1】：

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

这告诉我你的 Procfile 看起来像这样：

web: gunicorn blog_project.wsgi --log-file -

根目录下没有名称为blog_project且文件结尾为.wsgi的文件。

应该是这样的：

web: gunicorn blog_project/blog_project/wsgi:app

您可能希望将代码包装在根目录的 main.py 中，以便您可以这样做：

web: gunicorn main:app

【讨论】：

我将我的 ProcFile 修改为“web: gunicorn blog_project.blog_project.wsgi --log-file -”。但是现在 django 应用程序没有被检测到。 ModuleNotFoundError: 没有名为 'blog' 的模块。我能够成功运行“python manage.py runserver”。
你是如何在本地运行 gunicorn 的？这就是你在 Heroku 上运行 gunicorn 的方式。如果您没有从根文件夹执行 gunicorn。然后你需要做cd path/to/folder && gunicorn main:app。命令就是一个例子。你需要调整它。在 Procfile 中不要忘记 web: <command>
感谢@Tin 提供的信息。只需将 ProcFile、Pipfile、Pipfile.lock 移动到根文件夹 (blog/blog_project) 即可解决此问题。 ProcFile 内容：“web: gunicorn blog_project.wsgi --log-file -”
