【发布时间】：2021-08-28 03:23:14
【问题描述】：

打开 Heroku 运行时出现错误

应用程序错误

应用程序发生错误，您的页面无法访问 服务。如果您是应用程序所有者，请查看您的日志以获取详细信息。 您可以在 Heroku CLI 中使用以下命令完成此操作

heroku logs --tail

可能是什么问题？ DJANGO_SECRET_KEY 的问题会导致这样的问题吗？

这是我的日志

【问题讨论】：

  • 直接执行你的 django 项目，而不用把它隐藏在 gunicorn WSGI 后面。 Gunicorn 不会重定向错误日志。 Gunicorn 也不兼容所有 django 项目。
  • 你能告诉我怎么做吗？
  • 你是如何在本地执行你的项目的？你可能没有使用 gunicorn 来做到这一点。
  • 在这个项目示例中：github.com/ericmjl/minimal-flask-example python app.py 执行烧瓶应用程序而不将其隐藏在 gunicorn 后面。 web: gunicorn app:app 执行文件app.py，其中定义了对象app，并将其隐藏在WSGI 后面。请注意，在后一种情况下 app.py if __name__ == "__main__":returns False 因此最后一行不会执行。
  • 使用 gunicorn 应该没有问题。如果需要，可以添加 --log-file blah.txt 来保存日志。然后使用 heroku bash 查看文件内容。无论如何，wsgi.py 文件中有什么？ wsgi 中指定的设置文件是否存在？.. 还是您的设置设置与 Django 的默认方法不同？

【解决方案1】：

我的 Procfile 不正确 我把它从

web: gunicorn taskmate.wsgi

到

web: gunicorn taskmate.wsgi:application --log-file - --log-level debug
python manage.py collectstatic --noinput
manage.py migrate
