求助大神 最近在用python搭建网站模块出错

[floating12]

系统为centos6 ，python 3.5 已经安装好了django 然后在linux环境下使用django-admin 命令 是这样的：
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.).







然后在进行这步代码 python manage.py migrate 出现问题



Traceback (most recent call last):
File "manage.py", line 8, in <module>
from django.core.management import execute_from_command_line
ImportError: No module named 'django'

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
File "manage.py", line 14, in <module>
) from exc
ImportError: Couldn't import Django. Are you sure it's installed and available on your PYTHONPATH environment variable? Did you forget to activate a virtual environment?
