Heroku Django 崩溃：at=error code=H10 desc=“App crashed” method=GET path=“/”

【问题标题】：Heroku Django crashed: at=error code=H10 desc=“App crashed” method=GET path=“/”Heroku Django 崩溃：at=error code=H10 desc=“App crashed” method=GET path=“/”
【发布时间】：2021-08-18 17:12:08
【问题描述】：

我正在尝试在 Heroku 上部署我的 Django 项目。但每次都遇到同样的错误。 Heroku 重启对我不起作用。我清除了 buildpack 并添加了 python buildpack。这对我不起作用。我还尝试了不同的主机，例如ALLOWED_HOSTS = ['*', '127.0.0.1', 'dailynotes.herokuapp.com']。在 Procfile 中，我尝试了不同的方式，例如 web: gunicorn ToDoApps.wsgi: --log-file - 和

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

这对我不起作用。

【问题讨论】：

  • 你有 requirements.txt 文件吗？
  • @GiancarloVentura 是的。 requirements.txt 包含 dj-database-url==0.5.0 gunicorn==20.1.0 whitenoise==5.3.0

标签： django heroku webdeploy


【解决方案1】：

经过一些更改后它可以工作。我错过了运行 python3 manage.py collectstatic 。然后推送到github。我在部署之前删除了 buildpacks。并按照本教程https://www.codechit.com/django-github-auto-deployment-to-heroku/
