所以我开始使用Django。我安装了python，当我在CMD中运行python时，它运行良好。接下来，我下载并安装了Django，进入了python shell，导入了django并成功输出了它的版本。最后，我为我的项目创建了一个新目录，输入：
django-admin.py startproject mysite
我收到以下错误：
Type 'django-admin.py help <subcommand>' for help on a specific subcommand.
Available subcommands:
[django]
check
compilemessages
createcachetable
dbshell
diffsettings
dumpdata
flush
inspectdb
loaddata
makemessages
makemigrations
migrate
runserver
sendtestemail
shell
showmigrations
sqlflush
sqlmigrate
sqlsequencereset
squashmigrations
startapp
startproject
test
testserver
Note that only Django core commands are listed as settings are not properly configured
(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.).
我在Django的安装中做错了吗？
