Question

我在我的智慧＆＃39;结束这个问题，我希望你们中的一个人有答案。回溯命中一个不存在的文件！

我有生产和开发Django应用程序 - 所以我试图利用manage.py上的设置参数来运行manage.py即python manage.py runserver --settings=athena.settings.development

时访问正确的设置

为了完成这项工作 - 我移动了我的settings.py文件，其中包含令人讨厌的if / else结构和一些打印语句，以确保设置仍然可以读取以下内容我到settings/base.py。我创建了一个设置目录，并移动/重命名了settings.py。

athena/
 |-- athena/
 |    |-- __init__.py
 |    |-- settings/
 |    |    |-- __init__.py
 |    |    |-- base.py    <------
 |    |-- urls.py
 |    +-- wsgi.py
 +-- manage.py

manage.py无法读取的新settings/base.py - 默认为旧settings.py，因为您将在追溯中看到：

# BASE_DIR = os.path.dirname(os.path.dirname(__file__))
BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))

这是追溯：

回溯是指不存在的设置文件！它指的是一个已被移动的文件。我试图在我的DJANGO_SETTINGS_MODULE中对wsgi.py manage.py以及unset和.env中python manage.py runserver --settings=athena.settings.development的引用发表评论，但无济于事。我需要能够在前进之前更改参考。 python manage.py runserver --settings=athena.settings和{{1}}获得相同的结果。

分离生产/开发设置时，Django ghost settings.py文件
