Question

我是python和django的新手，最近我遇到了一些问题。 Django-admin.py runserver不起作用（ubuntu 12.04）。

终端错误代码：

    linas@ubuntu:~$ django-admin.py runserver
Traceback (most recent call last):
  File "/usr/local/bin/django-admin.py", line 5, in <module>
    management.execute_from_command_line()

    raise ImportError("Settings cannot be imported, because environment variable %s is undefined." % ENVIRONMENT_VARIABLE)
ImportError: Settings cannot be imported, because environment variable DJANGO_SETTINGS_MODULE is undefined.

感谢您的帮助。

编辑：这是我使用./manage.py runserver

时得到的

Answer 1

使用项目目录中的manage.py

cd project
./manage.py runserver

Answer 2

你可以发布你的模特吗？你也创建了数据库吗？

运行：

python manage.py syncdb

Answer 3

首先（我希望你已经这样做）创建一个带有项目名称的目录，然后启动执行命令的django项目： python django-admin.py startproject projname （如果没有正确执行，请删除关键字“python”并尝试）现在从同一目录运行python manage.py runserver。如果您已正确安装，您将获得：验证模型。。找到0个错误
