I have installed python 2.7.10 in windows. I installed django in path c:python27/scripts/with a command pip install django and created project with command django-admin startproject mysite from the same path.

Now to run server i cd to path c:python27/scripts/mysite and ran a command manage.py runserver/ manage.py runserver 0.0.0.0:8000 And this has no any effect.

where did i go wrong, and also i couldn’t run with python console. and i couldn’t redirect to my project from python CMD. all i did is from windows console.

Edit:
Screenshot of execution

First step was to set the environment variable.

windows key + pause or Control PanelSystem and SecuritySystem
Advance system settings (this will open system property)
navigate to Advanced tab > Environment variable
Edit path — append ;c:python27 in variable value field
Restart CMD

then /python manage.py runserver should work

Trying setting up a virtualenv for your project.

This same issue happened to me when trying to launch the test server

python .manage.py runserver

from PowerShell on Windows 10. According to the Django site, there might be an issue with the type of arguments being passed from PowerShell.

My workaround was to use a virtualenv. Once that was setup with django installed via pip, the runserver command worked.

The best solution is to install Python from Microsoft Store. In this case, you won’t have to worry about the Environmental Variables and Path. Windows will detect all that automatically.

Try this fix guys:
1. Right click on the windows icon/start on the bottom left and run Windows Powershell as admin.
2. Than type cd ~/ and later change the path again to the project folder.
3. type python manage.py runserver and press enter.

answered Aug 10, 2019 at 9:24

had the same problem. fixed it by checking python and django version compatibility. If you’re still battling with this update one or the other or ensure they’re both compatible with each other in the virtual’env’ you’re setting up.

good luck.

I think you forgot to add python to environment variables. So, During the installation, click the checkbox named «Add Python 3.9 to PATH» to add in environment variables. or you can simply add the path later.

When you open the command prompt on windows, the default directory might be C:WINDOWSSystem32>
Here, you have to change the directory by just adding cd to the default directory. Then copy the directory of where your project is and paste with one space. So it will be:
C:yourfolderyourproject>
Next, use the comman which is, python manage.py runserver

That’s all 😅

After setting C:Python in the environment variables, issuing the following command helped:

py manage.py runserver

Providing some more code or examples of your directory structure might help.

First, the command is generally manage.py runserver 8000, so try that, and that make might a difference.

Second, in Django 1.4, the location of the settings.py file was moved. In previous versions of Django, the directory structure looked like this:

myproject/
    settings.py
    views.py
    urls.py
    myapp/
        models.py
        ...
    ...

However, in Django 1.4, the main project settings and files were moved to a different directory:

myproject/
    myproject/
        settings.py
        views.py
        urls.py
    myapp/
        models.py
        urls.py
        ...
    ...

So if you’re using Django 1.4 but going off of previous examples, your settings.py might be in the wrong place. Additionally, I’ve found that when running django-admin.py startproject, it sometimes incorrectly creates two settings.py files, once in the old location and one in the new, which could be additionally confusing you. The only one that manage.py would pay attention to is the one in the project’s directory.

If it turns out that your settings.py is in the wrong place but you don’t want to move it, as your error suggests, you could set an environmental variable called DJANGO_SETTINGS_MODULE as the path to the Django settings.py you’d like to use for your project. I definitely don’t recommend doing this.

Что делать?

Версия python: 3.6.3

Версия django: 2.2.2

Заранее благодарен!

Providing some more code or examples of your directory structure might help.

First, the command is generally manage.py runserver 8000, so try that, and that make might a difference.

Second, in Django 1.4, the location of the settings.py file was moved. In previous versions of Django, the directory structure looked like this:

myproject/
    settings.py
    views.py
    urls.py
    myapp/
        models.py
        ...
    ...

However, in Django 1.4, the main project settings and files were moved to a different directory:

myproject/
    myproject/
        settings.py
        views.py
        urls.py
    myapp/
        models.py
        urls.py
        ...
    ...

Python не находит Django

(docker) andreyolegovich.ru@server:~/HelloDjango [0] $ python3 manage.py runserver
Traceback (most recent call last):
File «manage.py», line 8, in <module>
from django.core.management import execute_from_command_line

ModuleNotFoundError: 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?

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.

Проверьте, всё ли правильно прописали в

settings.py

ALLOWED_HOSTS.

Выключите Django, закройте все консоли подключенные к хостингу или все консоли на локальной машине.

Очистите кэш браузера или откройте url другим браузером.

Не работает runserver Django

Если Вы выполняете команду

python3 manage.py runserver

И ничего не происходит, или например, у Вас работал самый первый проект, а запустить
второй не получается — скорее всего дело в хостинге. На нём может быть закрыта
возможность слушать порты и выбор рабочего проекта происходит с помощью
какого-то скрипта.

Если Вы, как и я, пользуетесь
хостингом beget
, тот этот скипт будет называться

passenger_wsgi.py

и лежать будет на одном уровне с директорией public_html.

Пропишите в нём

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

Также советую перепроверить не забыли ли Вы поменть системный путь на нужный Вам проект.

При смене проекта обычно нужно делать два изменения в файле passenger_wsgi.py

# -*- 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.

DJANGO – это удобный и мощный фреймворк для создания веб-приложений на Python. Однако, при запуске сервера на Django могут возникнуть некоторые проблемы. В этой статье мы рассмотрим частые ошибки и как их решить.

Ошибка «ModuleNotFoundError: No module named ‘django’»

Такая ошибка возникает, если Django не установлен на компьютере. Чтобы решить эту проблему, необходимо установить Django с помощью pip:

pip install Django

Ошибка «Error: Target WSGI script not found or unable to stat»

Такая ошибка указывает на проблему с файлом WSGI. Для ее решения необходимо проверить, указан ли правильный путь к файлу WSGI в конфигурационном файле. Также следует убедиться, что файл WSGI находится в нужной директории.

Ошибка «Port 8000 is already in use»

Если вы видите такое сообщение, значит порт 8000 уже используется другим приложением. Чтобы решить эту проблему, можно изменить порт для запуска сервера. Для этого нужно указать другой номер порта, например 8080:

python manage.py runserver 8080

Ошибка «no module named ‘myapp’»

Если вы создали приложение с именем «myapp», а Django не может найти его, то нужно проверить, правильно ли указано имя приложения в конфигурационном файле настроек.

Ошибка «TypeError: ‘xxx’ object is not callable»

Такая ошибка возникает, когда используется несуществующий метод или пропущен аргумент. Необходимо проверить код и убедиться, что все методы используются правильно и все аргументы передаются в нужном порядке.

Ошибка «SyntaxError: invalid syntax»

Такая ошибка возникает, если код содержит синтаксические ошибки. Чтобы решить эту проблему, нужно внимательно проверить код и исправить все ошибки.

Заключение

В данной статье мы рассмотрели частые ошибки при запуске сервера на Django и как их решить. Важно помнить, что большинство проблем можно решить, внимательно следуя инструкциям и проверяя код.
