Django项目初始设置中的问题

Question

我正在从官方文档中学习Django，在学习https://docs.djangoproject.com/en/1.7/intro/tutorial01/的教程时，我一直在创建项目部分。

当我运行django-admin.py startproject mysite时，出现以下错误

C:\Python34>django-admin.py startproject mysite
Usage: django-admin.py subcommand [options] [args]
Options:
  -v VERBOSITY, --verbosity=VERBOSITY
                        Verbosity level; 0=minimal output, 1=normal output,
                        2=verbose output, 3=very verbose output
  --settings=SETTINGS   The Python path to a settings module, e.g.
                        "myproject.settings.main". If this isn't provided, the
                        DJANGO_SETTINGS_MODULE environment variable will be
                        used.
  --pythonpath=PYTHONPATH
                        A directory to add to the Python path, e.g.
                        "/home/djangoprojects/myproject".
  --traceback           Raise on exception
  --no-color            Don't colorize the command output.
  --version             show program's version number and exit

    sqlmigrate
    sqlsequencereset
    squashmigrations
    startapp
    startproject
    syncdb
    test
    testserver
    validate

注意，只有Django core命令被列为未正确配置的设置

error: Requested setting INSTALLED_APPS, but settings are not configured
    . You must either define the environment variable DJANGO_SETTINGS_MODULE or call settings.configure() before accessing settings.).

我使用的是Python3.4.1和Django1.7。我没有安装任何其他Django版本，这是我正在创建的第一个项目。

Answer 1

确保遵循troubleshooting guide，因为看起来系统路径上没有django-admin.py。从文档中：

django-admin.py should be on your system path if you installed Django via python setup.py. If it’s not on your path, you can find it in site-packages/django/bin, where site-packages is a directory within your Python installation. Consider symlinking to django-admin.py from some place on your path, such as /usr/local/bin.

您还应该为每个项目使用一个virtualenv，以便隔离每个项目的依赖项并简化对它们的管理。virtualenvwrapper是创建和管理虚拟机的有用工具。

Answer 2

您只需运行django-admin startproject mysite（注意：不是django-admin.py），因为如果通过pip安装django，名为“django admin.exe”的可执行程序将被添加到环境变量“PATH”中的“C:\ Python34\Scripts”（如果不是，则将其添加到PATH）。
