Python 持续导入错误：无法导入设置'；myapp.settings'；错误

这个问题似乎有很多潜在的解决方案，但对我来说似乎什么都不管用

运行

python manage.py运行服务器

很好，但在尝试使用任何选项运行

django admin.py

-时会出现错误。实际上，我正在尝试做一个

django-admin.py dumpdata myapp

Traceback (most recent call last):
File "/Users/lemon/.virtualenvs/ram/bin/django-admin.py", line 5, in <module>

% (self.SETTINGS_MODULE, e)
ImportError: Could not import settings 'ram.settings' (Is it on sys.path? Is there an import error in the settings file?): No module named ram.settings

我使用的是virtualenvrapper，我已经重新安装，没有问题

manage.py

如下所示：

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

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

    from django.core.management import execute_from_command_line

    execute_from_command_line(sys.argv)

我不太清楚还有什么地方可以这样做——非常感谢您的帮助。谢谢

尝试按照建议修改

PYTHONPATH

，现在出现类似错误：

django.core.exceptions.ImpropertlyConfigured:请求设置调试，但未配置设置。在访问设置之前，必须定义环境变量DJANGO_SETTINGS_MODULE或调用SETTINGS.configure（）。

试试：

这似乎是一个路径问题。调用

manage.py

的路径通常会添加到PYTHONPATH中，如果调用django-admin.py则不会。 因此，您的应用程序找不到

ram

模块。您需要将

manage.py

所在的文件夹添加到PYTHONPATH

编辑

django.core.exceptions.ImpropertlyConfigured:请求设置调试，但未配置设置。在访问设置之前，必须定义环境变量DJANGO_SETTINGS_MODULE或调用SETTINGS.configure（）

意味着你必须告诉django哪些设置。因此，请输入以下行

export DJANGO_SETTINGS_MODULE='ram.settings'

或者按以下方式启动django admin

django-admin.py runserver --settings='ram.settings'

---

（当然是更换了蟒蛇路径）

谢谢，但运气不好。已编辑原始帖子以反映新的错误消息。您现在遇到另一个问题：没有为django admin设置设置文件。我根据宾果编辑了我的文章！非常感谢你，先生。顺便问一下，你知道这是怎么发生的吗？什么都没发生；）。

django admin.py

（全局）无法了解特定于项目的设置。仔细查看

manage.py

。在那里，设置了

DJANGO\u设置\u模块。
export DJANGO_SETTINGS_MODULE='ram.settings'

django-admin.py runserver --settings='ram.settings'
