Question

我有一个完全在本地运行的django应用程序，但是当我尝试在heroku上部署它时，我继续遇到此错误，

django.core.exceptions.ImproperlyConfigured: Requested setting LOGGING_CONFIG, but settings are not configured. You must either define the environment variable DJANGO_SETTINGS_MODULE or call settings.configure() before accessing settings.

这是我的设置文件

这是我的wsgi.py

import os

from django.core.wsgi import get_wsgi_application
from whitenoise.django import DjangoWhiteNoise

application = get_wsgi_application()
application = DjangoWhiteNoise(application)

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

application = get_wsgi_application()
application = DjangoWhiteNoise(application)

很明显我的DJANGO_SETTINGS_MODULE已定义。

我找不到调用LOGGING_COFIG的行抛出错误。我也不知道调用setup（）的位置。

我在这里做错了什么？

Answer 1

当您没有定义DJANGO_SETTINGS_MODULE环境变量时，通常会发生这种情况。

在这种情况下，您的.wsgi文件包含：

application = get_wsgi_application()
application = DjangoWhiteNoise(application)

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

application = get_wsgi_application()
application = DjangoWhiteNoise(application)

并且错误来自第一行调用get_wsgi_application()，该调用没有在环境中定义DJANGO_SETTINGS_MODULE。

Answer 2

设置环境时遇到了同样的问题。

我的解决方案是打开终端并手动设置环境

以下是步骤：（对于Mac）

打开终端并输入vim〜/ .bash_profile

添加以下行：

PATH=${PATH}:/Users/work/workspace/[virtual_environment]/bin
PYTHONPATH=${PATH}:/Users/work/PycharmProjects/[project_name]
DJANGO_SETTINGS_MODULE=[project_name].settings

键入:wq保存并退出终端
键入源〜/ .bash_profile以重新加载它
