我一直在尝试在 heroku 上部署我的 django 项目，并且一个星期以来一直在反对这个错误。一切都在本地运行良好，但是当我推送到 heroku 时，我得到的只是 heroku logs --tail

我的Procfile：

不正确 web: gunicorn mysite.mysite.wsgi

解决方案

    web: gunicorn --chdir mysite mysite.wsgi
    release: cd mysite && python manage.py migrate

ch-dir mysite 是关键区别，根据我的理解，迫使 gunicorn 专门针对 mysite/mysite 定位 wsgi.py

我的wsgi.py：

import sys

from django.core.wsgi import get_wsgi_application

path = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))
if path not in sys.path:
    sys.path.append(path)

os.environ['DJANGO_SETTINGS_MODULE'] = 'mysite.settings'
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "mysite.settings")

application = get_wsgi_application()

和我的目录： picture of my directory, Procfile on same level as manage.py

非常感谢任何帮助或指导

2 个答案:

答案 0 :(得分：0)

在 Procfile 中，您只需要指定 wsgi 路径。 您的 Procfile 文件应如下所示：

web: gunicorn mysite.wsgi --log-file -

答案 1 :(得分：0)

将我的 Procfile 更改为

    web: gunicorn --chdir mysite mysite.wsgi
    release: cd mysite && python manage.py migrate

通过将当前工作目录更改为父目录 ModuleNotFound: no module named 'mysite.settings' 来解决 mysite。感谢两位的帮助，虽然没有直接解决问题，但为我指明了正确的方向。
