django-admin 运行服务器错误
django-admin runserver error
我为 python 2.7
设置了 virtualenv
16% source Work/Django/env/bin/activate
接下来创建项目
django-admin startproject myproject
创建应用程序
cd myproject
django-admin startapp contact
并尝试 运行 开发服务器
16% django-admin runserver
我收到一个错误

How fix this error?
如果您查看 manage.py 脚本的作用（此脚本是在您 运行 django-admin startproject myproject 时在 myproject 目录中创建的），它会导出环境变量DJANGO_SETTINGS_MODULE 然后是 运行s django-admin（好吧，它通过 django.core 做到了，但它几乎做到了）。
django-admin 需要知道项目设置的 python 模块，并且该信息存在于该环境变量中。
因此，在 myproject 目录中，您应该 运行:
python manage.py runserver
和 manage.py 脚本将为您设置环境， 或 您可以强制 django-admin 从命令行读取设置位置：
django-admin runserver --pythonpath=. --settings="myproject.settings"
如果您将项目目录包含在默认的 pyhton 路径中，则不需要 --pythonpath 开关。
mkdir djangoproject
cd djangoproject/
pip install virtualenv
virtualenv myvenv
pip freeze
which python
source myvenv/bin/activate
pip install django
pip freeze
django-admin startproject myproject
cd myproject/
python manage.py runserver
您的项目将成功启动
django-admin startapp myapp
现在，您需要进行一些与您创建的应用程序相关的设置。 (settings.py & urls.py)
