Python 在Heroku上部署Flask应用程序-web1:崩溃

我正在尝试将Flask应用程序部署到Heroku，但收到以下错误：

(venv)rgb:~/flaskapp/app$ heroku ps
=== web (1X): `gunicorn app:app`
web.1: crashed 2014/07/09 21:39:45 (~ 10s ago)

它与“foreman start”一起在本地工作，但将其推到Heroku上会导致网络崩溃：

(venv)rgb@rgb-K45VD:~/flaskapp/app$ foreman start 
21:41:01 web.1  | started with pid 3269

以下是heroku日志： （venv）rgb@rgb-K45VD:~/flaskapp/app$heroku日志

这似乎是一个错误：

任何帮助都将不胜感激

从表面上看代码，我看不出有什么问题。你试过在自己的机器上运行它吗

顺便说一下，代码中有一些东西导致它无法在我的机器上运行：

• 需要有一个环境变量“APP_SETTINGS”（您设置了吗？）
• 需要一个models.py模块——可能包含BlogPost类。GitHub上似乎没有这样的文件
• 你安装了炼金术吗

---

确保将程序文件从web:gunicorn app:app更改为web:gunicorn project:app。 此外，一旦部署到heroku，数据库也会出现问题。最好的办法是“删除”数据库并创建一个新的数据库或进行迁移。

使用命令heroku logs获取更多信息。

请不要让我检查整个项目并为您调试。。您试图找出错误的位置是什么？顺便问一下：在您的repo中的多个文件中存在合并冲突（这将导致语法错误）
