Gunicorn无法识别Wagtail CMS

Question

我正在把我的网站从Mezzanine迁移到Wagtail，这个过程是在一台使用virtualenv的Debian机器上进行的。但是在我设置好Wagtail、用户权限和源代码后，当我在wagtail文件夹里运行# gunicorn_django时，出现了以下错误信息：

Traceback (most recent call last):
  File "/home/user/userblog/local/lib/python2.7/site-packages/gunicorn/arbiter.py", line 495, in spawn_worker
    worker.init_process()

据我所知，我的设置跟之前的Mezzanine没有什么不同，而且我知道Wagtail也是基于Django的。有人知道问题可能出在哪里吗？

gunicorn_django 从 Gunicorn 18 版本开始就不再推荐使用了。如果可以的话，建议你使用 WSGI 接口来配合 Django。具体可以查看 Django 和 Gunicorn 的文档。

不过，如果你还是在使用 gunicorn_django，并且你的设置不在 settings.py 文件里，而是在其他模块中，那么你可以通过指定相关设置文件的路径来让它正常工作。比如，在你的 mywagtailproject 文件夹里，设置文件可能是 mywagtailproject/settings/production.py（注意，你的 mywagtailproject 文件夹里会有一个同名的 mywagtailproject 子文件夹）：

gunicorn_django --settings=mywagtailproject.settings.production --pythonpath=/pathto/mywagtailproject

你可能需要设置 --pythonpath 这个参数，也可能不需要。
