django重组后无法导入wsgi？

Question

我的初始项目结构是这样的：

manage.py
foo/
  wsgi.py
  settings.py
  urls.py
  __init__.py

manage.py

#!/usr/bin/env python
import os
import sys

if __name__ == "__main__":
    os.environ.setdefault("DJANGO_SETTINGS_MODULE", "foo.settings")

    from django.core.management import execute_from_command_line

    execute_from_command_line(sys.argv)

新结构：

manage.py
src/
   foo/
      wsgi.py
      settings.py
      urls.py
      __init__.py

manage.py

#!/usr/bin/env python
import os
import sys
project_root = os.path.dirname(os.path.abspath(__file__))

print project_root 

if __name__ == "__main__":
    sys.path.insert(0, os.path.join(project_root, 'src'))

    os.environ.setdefault("DJANGO_SETTINGS_MODULE", "foo.settings")

    from django.core.management import execute_from_command_line

    execute_from_command_line(sys.argv)

然后在部署期间，我有ImportError: No module named foo.wsgi的错误：

django在重组后未能导入wsgi

wsgi.py

import os

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "foo.settings")

from django.core.wsgi import get_wsgi_application
application = get_wsgi_application()

有什么想法吗？

修改

我用它来运行：

$ gunicorn src.foo.wsgi:application 
2017-05-20 17:33:52 [22227] [INFO] Starting gunicorn 18.0
2017-05-20 17:33:52 [22227] [INFO] Listening at: http://127.0.0.1:8000 (22227)

2017-05-20 17:33:52 [22231] [INFO] Booting worker with pid: 22231

但是当我在http://127.0.0.1:8000/访问该网站时，我收到此错误：

ImportError: Could not import settings 'foo.settings' (Is it on sys.path?): No module named foo.settings

编辑2：

我必须向所有src.添加foo.：

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "src.foo.settings")
ROOT_URLCONF = 'src.foo.urls'

有更好的方法吗？

Answer 1

manage.py在这里完全不相关，因为你在开枪时不使用它。

问题可能是你需要__init__.py目录中的空foo来使它成为Python可以导入的包。
