我在windows xp上创建了一个项目示例和一个app sampapp当我尝试使用命令sqlall时，我收到以下错误。

C：\ Python27 \ Django-1.3.1 \ django \ bin＆gt; django-admin.py sqlall sampapp

 ImportError: Settings cannot be imported, because environment variable

有人可以帮我解决这个问题吗？

Answer 1

导航到您的项目目录并在那里运行本地manage.py。

C:\...\my_project_where_sampapp_lives\> python manage.py sqlall sampapp

当您使用'python manage.py'时，您正在使用'django-admin.py'

$ django-admin.py shell
Error: Settings cannot be imported, because environment variable DJANGO_SETTINGS_MODULE is undefined.
$ python manage.py shell
...
>>> print "now it works"

Answer 2

应指定DJANGO_SETTINGS_MODULE，我通常将此行添加到我的.bashrc文件中：

导出PYTHONPATH =。 DJANGO_SETTINGS_MODULE = yoursettingsfile

Answer 3

Django-admin.py正在查找您无法找到的项目settings.py文件，因此会引发ImportError。似乎在使用django-admin.py命令时没有导航到项目目录。

您需要做的就是导航到您的项目目录。类似的东西：

（假设您的项目名称是我的项目）

cd myproject

然后运行

django-admin.py sqlall sampapp

Django导入错误说django设置环境变量是未定义的
