Question

我正在尝试将Flask应用程序部署到Heroku，但我收到了这个错误：

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

它在本地工作“工头开始”，但在Heroku上推动网络崩溃：

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

这是以下heroku日志：（venv）rgb @ rgb-K45VD：〜/ flaskapp / app $ heroku logs

这似乎是错误：

这是我的app.py：

非常感谢任何帮助！

Answer 1

从表面上看代码，我认为没有任何问题。您是否尝试在自己的机器上运行它？

顺便说一句，代码中有一些东西导致它无法在我的机器上运行：

需要一个环境变量“APP_SETTINGS”（你设置了吗？）
需要有一个models.py模块 - 可能包含BlogPost类。好像GitHub上没有这样的文件？
你安装了flask-sqlalchemy吗？

Answer 2

确保您将procfile从 web：gunicorn app：app 更改为 web：gunicorn project：app 。此外，一旦部署到heroku，您将遇到数据库问题。最好的选择是＆＃34; DROP＆＃34;数据库并创建一个新的或迁移。使用命令 heroku日志获取更多信息。
