wsgi.py文件如下:

"""
WSGI config for pom project.

It exposes the WSGI callable as a module-level variable named ``application``.

For more information on this file, see
https://docs.djangoproject.com/en/1.8/howto/deployment/wsgi/
"""

import os

from django.core.wsgi import get_wsgi_application
import sys
from os.path import abspath, dirname, join
#sys.path.insert(0, '/home/ubuntu/deploy/pom')
sys.path.insert(0, abspath(join(dirname(__file__), "../")))
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "pom.settings")

application = get_wsgi_application()

最佳答案

错误消息清楚地说:

ImportError: No module named allauth

populate() 不可重入错误是当 mod_wsgi 尝试重新加载 WSGI 脚本文件时发生的错误，在第一个错误之后，发现 Django 由于第一个错误而初始化了一半，因此它放弃了。

修复了找不到 allauth 模块的问题，后一个错误应该会消失。

关于django - 运行时错误 : populate() isn't reentrant in Django，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/31611117/
