我在 windows xp 上创建了一个项目示例和一个应用程序 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>django-admin.py sqlall sampapp

有人可以帮我解决这个问题吗？

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

当您应该使用“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"

Django-admin.py 正在寻找settings.py它无法找到的项目文件，因此它会引发 ImportError。好像您在使用 django-admin.py 命令时没有导航到您的项目目录。

您需要做的就是导航到您的项目目录。就像是：

（假设你的项目名称是我的项目）

cd myproject

然后运行

django-admin.py sqlall sampapp

应该指定 DJANGO_SETTINGS_MODULE，我通常将这一行添加到我的 .bashrc 文件中：

导出 PYTHONPATH=。DJANGO_SETTINGS_MODULE=你的设置文件
