在heroku上部署django应用 - 在服务器上找不到请求的URL

Question

我一直在关注djangogirl的教程http://tutorial.djangogirls.org/en/deploy/README.html在Heroku上部署django应用。我是一个完整的新手，所以很多东西对我来说似乎都是黑魔法，我对发生的事情有一个非常模糊的概念。但是，我似乎已经能够从创建我的应用程序到将其推送到远程存储库并运行Web进程，从而使所有事情顺利进行。

>heroku create 
>git push heroku master 
>heroku ps:scale web=1 

当我打开后该应用程序的URL，我得到的错误页面，该教程称，预计因为我还没有填补了空数据库“此服务器上找不到请求的URL”。所以它说运行

>heroku run python manage.py migrate 
>heroku run python manage.py createsuperuser 

当我跑他们两个的命令似乎执行良好。我试着再次尝试运行manage.py migrate，但它只是说没有更多的迁移适用。我可以很好地登录到管理页面，但试图打开应用程序url本身仍然给我一个'请求的网址在该服务器上找不到'的错误页面，即使在我应用迁移后。

就像我说的，我是一个真正的新手，所以我迷失在我应该如何解决这个问题。我一直在按照教程一步一步，并不知道我出错的地方。非常感谢帮助。

另外，我使用的是Windows 8，我还是刚开始使用命令行的工作，因此，如果这需要任何命令行疑难解答我”如果你能给我Windows命令，我会非常感激（尽管如果你给我Unix命令，我很乐意搜索Windows等价物）

Answer 1

不知何故，我似乎设法解决它，虽然我不知道确切的问题是什么。我所做的第一个改变是添加了行

psybopg2==2.5.4 

在requirements.txt文件

，该教程说是必需的，但我好像错过了（唉）。但即使在部署更新后的存储库后，我仍然得到了同样的'URL not found'错误页面。我认为不会影响任何东西的下一次更改（由绝望决定），是在mysite \ settings.py文件的某些赋值语句的'='符号之间添加空格。部署后，仍然没有运气。

我决定在这一点继续教程和稍后解决这个问题，所以我调整并创建了一些不应该影响部署过程的文件（编辑mysite \ urls.py，blog \ views.py，创建blog \ urls.py和一个html模板文件，post_list.html）。然后我意识到，我已经跟着教程把

python-3.4.2 

在runtime.txt文件，但我是在本地运行的python-3.4.1，所以我改变了指定的版本号。这次在部署之后，我得到了一个服务器错误（500），但我怀疑我在指定mysite \ view.py中定义的视图所呈现的模板的路径中放置的反斜杠（即blog \ post_list .html），以便网站在本地运行（在Windows上）没有错误。用正斜杠（blog/post_list.html）替换并再次部署，它奇迹般地工作！

所以我怀疑是改变python运行时是什么解决了这个问题，但是再一次，为什么呢？如果未指定它，Heroku是否默认使用Python 2.7.9，以及本地版本的python如何影响服务器上文件的运行？

Answer 2

你能否确认你正在访问的URL等同于运行以下命令时输出的URL ：

heroku info -s | grep web_url | cut -d= -f2 

另外，如果你运行以下内容，你发现什么与众不同吗？

heroku logs
