因此，我有一个已经存在的Django项目（称为“MLshowcase”），我在过去几个月里建立了这个项目。我第一次尝试部署到Heroku，已经完成了所有步骤并添加了我认为需要的所有文件。在大约50次失败（需求太大）之后，我终于得到了要部署的项目！注意：为了部署，我必须在heroku上禁用collectstatic，否则它会一直说我的一个静态文件“不在根‘static’中”。但它确实部署了

然而，转到应用程序（在heroku上称为‘iansworld’）只会显示“应用程序错误，无法提供页面”。我已经摆弄了一天的设置和wsgi，但仍然一无所获。当我查看Herko日志时，它显示为build-crash-build-crash..等等，其中一些日志说：

app[web.1]: ModuleNotFoundError: No module named 'iansworld'

我在本地收集static，因此在根目录中有“static”和“staticfiles”。在成功部署之前，我能够在当地服役。那一定是配置问题吧
