Gunicorn.errors.HaltServer: 姜戈

我有一个 django 应用程序，并尝试首先使用 Gunicorn 设置它，然后使用主管和 nginx 设置它。

该应用程序正在使用正常的 django 命令运行，就像python manage.py runserver

我使用 pip 安装了 Gunicornpip install gunicorndjango 版本是1.5.3

当我在虚拟环境中运行以下命令时，如下所示

gunicorn hello.wsgi:application -b xx.xxx.xxx.xx:8000并面临错误

Traceback (most recent call last):
  File "/root/Envs/proj/bin/gunicorn", line 9, in <module>
    load_entry_point('gunicorn==19.0.0', 'console_scripts', 'gunicorn')()

    raise HaltServer(reason, self.WORKER_BOOT_ERROR)
gunicorn.errors.HaltServer: <HaltServer 'Worker failed to boot.' 3>

那么为什么实际上会遇到上述错误以及解决方法是什么？

用--preload运行guncorn可以看到错误日志，像这样

gunicorn app:application --preload -b 0.0.0.0:5000 

这通常会给您更详细的错误消息。
