Ошибка при запуске сервера django

Выпадает ошибка при запуске сервера Django. Вроде пишет, что ошибка в кодировке, но я не знаю как её исправить.

Python не находит Django

Причина в том, что в PATH не прописан путь до python. Вернитесь к шагу
PATH

Disallowed host

Вы можете запустить Django с помощью

python3 manage.py runserver

И прописали в

settings.py

свои хосты, например так

ALLOWED_HOSTS = ['http://www.andreyolegovich.ru','127.0.0.1','localhost','andreyolegovich.ru','www.andreyolegovich.ru']

Но при обращении к домену в браузере появляется ошибка DisallowedHost

DisallowedHost at /
Invalid HTTP_HOST header: ‘www.andreyolegovich.ru’. You may need to add ‘www.andreyolegovich.ru’ to ALLOWED_HOSTS.

Не работает runserver Django

Если Вы выполняете команду

python3 manage.py runserver

os.environ[‘DJANGO_SETTINGS_MODULE’] = ‘Название_нового_прокта.settings’

Web application could not be started

Если Вы хотите переключиться между проектами и уже обновили скрипе passenger_wsgi.py
но получили ошибку

Web application could not be started

Скорее всего Вы забыли пересоздать файл tmp/restart.txt

(docker) andreyolegovich@server:~/andreyolegovich.ru [0] $ touch tmp/restart.txt

# -*- coding: utf-8 -*-
import os, sys
sys.path.insert(0, ‘/home/a/andreyolegovich/andreyolegovich.ru/public_html/Project_1’)
#sys.path.insert(0, ‘/home/a/andreyolegovich/andreyolegovich.ru/public_html/Project_2’)
sys.path.insert(1, ‘/home/a/andreyolegovich/.local/lib/python3.7/site-packages’)
os.environ[‘DJANGO_SETTINGS_MODULE’] = ‘Project_1.settings’
#os.environ[‘DJANGO_SETTINGS_MODULE’] = ‘Project_2.settings’
from django.core.wsgi import get_wsgi_application
application = get_wsgi_application()

Ещё одна возможная причина — незаданные переменные в файле

manage.py

You have 18 unapplied migration(s). Your project may not work properly until you apply the migrations for app(s): admin, auth, contenttypes, sessions.

Run ‘python manage.py migrate’ to apply them.

python3 manage.py migrate

ERROR: Can not perform a ‘—user’ install. User site-packages are not visible in this virtualenv.

Если вы пользуетесь виртуальным окружением флаг —user вам скорее всего вообще не нужен.

I am not sure how to fix this issue

I have no idea why I am getting this error when I try to runserver:
