Question

我已经浏览了开发中心提到的heroku教程。该应用程序显示并正常工作。当我尝试heroku日志时，我会看到如下所示的日志：

2012-11-20T12:40:13+00:00 heroku[run.1]: Awaiting client
2012-11-20T12:40:13+00:00 heroku[run.1]: Starting process with command `python manage.py syncdb`
2012-11-20T12:40:13+00:00 heroku[run.1]: State changed from starting to up
2012-11-20T12:40:43+00:00 heroku[run.1]: Error R13 (Attach error) -> Failed to attach to process
2012-11-20T12:40:44+00:00 heroku[run.1]: Process exited with status 128

2012-11-20T13:28:35+00:00 heroku[run.1]: State changed from up to complete

这意味着它正在运行，但是当我尝试时：

heroku run python manage.py syncdb

它没有运行，堆栈跟踪就在这里：

$ heroku run python manage.py syncdb
/Users/myusername/.heroku/client/lib/heroku/helpers.rb:103: warning: Insecure world writable dir /usr/local in PATH, mode 040777

可能有什么问题？

我刚遇到这个问题并设法找到解决方案。我将首先使用以下命令检查heroku日志：

heroku logs

这应该提供更多的见解。 syncdb无法正常工作的一个常见问题是您尚未更新您的requirements.txt

为此，将管道冻结冻结为requirements.txt

pip freeze > requirements.txt

这可能不是你遇到的确切问题，但是heroku日志应该是一个好的开始。

heroku python管理py syncdb无法正常工作
