Question

我已经在Heroku中成功部署了名为MyPortfolio的Python / Django应用。但是，当我尝试打开它时，出现了一个错误： ModuleNotFoundError：没有名为“ jobs”的模块项目文件夹为“ MeryPortfolio-project”。项目名称为“ MeryPortfolio”。应用程序名称为“职位”。因此Heroku找不到该应用程序的模块。

情况是：我尝试进行本地设置和生产设置。启动本地服务器时使用的本地设置。生产设置在Heroku中通过以下命令使用： heroku config：set DJANGO_SETTINGS_MODULE = MeryPortfolio-project.MeryPortfolio.settings.production 这些目录是： “ MeryPortfolio项目” /'MeryPortfolio'： _init .py settings.py urls.py wsgi.py /设置： 初始化 .py base.py local.py production.py

这些是我尝试打开应用程序（heroku打开）时的日志

请帮助您了解应用程序打开问题所在的位置。

Answer 1

在Python中，您不能包含带有破折号（-）的程序包/模块。在这种情况下：

DJANGO_SETTINGS_MODULE=MeryPortfolio-project.MeryPortfolio.settings.production

不应该工作。

在您的树形结构中，我看不到jobs应用的位置以及您的manage.py文件在哪里。另外，您也没有告诉我们如何在heroku中启动WEB服务器。

据我所知，我猜它的结构如下：

'MeryPortfolio-project'
    /'MeryPortfolio':
        ...
    /'jobs':
        ...
    'manage.py'

在这种情况下，您的设置模块应仅为MeryPortfolio.settings.production。如果manage.py在MeryPortfolio-project内部，并且您以manage.py runserver开始项目（这对生产不利），它将在python路径中自动添加MeryPortfolio-project。如果您使用的是gunicorn或其他方法，则需要确保将MeryPortfolio-project添加到python路径

我可以看到此错误：

2019-07-18T12:54:14.745087+00:00 app[web.1]: ModuleNotFoundError: No module named 'jobs'
2019-07-18T12:54:14.917101+00:00 heroku[web.1]: State changed from starting to crashed
2019-07-18T12:54:14.897138+00:00 heroku[web.1]: Process exited with status 1
2019-07-18T12:54:15.655426+00:00 heroku[router]: at=error code=H10 desc="App crashed" method=GET path="/" host=Host.host request_id=d98baa30-b9ee-4835-8b9b-9ef0414036d0 fwd="195.24.36.69" dyno= connect= service= status=503

有503服务不可用，这意味着该错误与部署无关，我相信，您是否在本地尝试过此代码，很可能是忘记了模块导出或类似的操作，我不是python开发人员？

应用程序（Python Django，PostgreSql）已成功部署在Heroku上，但是尝试打开时出现错误
