How do I run an existing Django file? - python

I downloaded a folder with multiple python files in the form of a Django project for a course and I am unable to run it. Usually, when you create a Django project it is created within the terminal with the line django-admin startproject web_project . and then python manage.py migrate is used and then the line python manage.py runserver to start a server.
How do I start a server to run my project?
When I use django-admin startproject web_project ., it creates a new project which I don't want. When I use python manage.py migrate or python manage.py runserver it says:
Command 'python' not found, did you mean:
command 'python3' from deb python3
command 'python' from deb python-is-python3
But even when I used python3 manage.py migrate or python3 manage.py runserver instead and it returned:
python3: can't open file 'manage.py': [Errno 2] No such file or directory


At first make sure you opened command prompt or terminal in right directory(in projects directory) when you are running the runserver command.
If you are on windows open the project folder(the folder that contains files like manage.py), then right click and press open PowerShell window here.


first of all I recommend creating a virtual environment using the following command
python3 -m venv .env
then activate it
source .env/bin/activate
"django-admin statproject" its for initalite a new project for running an excited Django app you should just install Django - if there is now "requirements.txt" file- , migrate and run.
pip install Django
python manage.py migrate
python manage.py runserver

Manage.py unknown command

I am a student and my profesor needs me to install Django on PyCharm.
I made a big folder called PyCharmProjects and it includes like everything I have done in Python.
The problem is that I made a new folder inside this PyCharmProjects called Elementar, and I need to have the Django folders in there but it's not downloading.
I type in the PyCharm terminal django-admin manage.py startproject taskmanager1 (this is how my profesor needs me to name it)
After I run the code it says:
No Django settings specified.
Unknown command: 'manage.py'
Type 'django-admin help' for usage.
I also tried to install it through the MacOS terminal but I don't even have acces the folder named Elementar (cd: no such file or directory: Elementar) although it is created and it is seen in the PyCharm.

Manage.py its python file after you start your project, you cant call this file until this command:
django-admin startproject mysite
Then run:
python manage.py runserver
And if you want apps in your project run:
python manage.py startapp my_app

First of all, you can't create a project using manage.py because the manage.py file doesn't exist yet. It will be created automatically in the folder taskmanager1 if you run the command below.
You can create a project with the command
django-admin startproject taskmanager1
After that you can change the directory to the taskmanager1 folder with the cd taskmanager/ command.
When you changed the directory you can use the python manage.py commando for example if you want to run your migrations or creating an app.
python manage.py migrate

How to create an executable file with multiple commands?

I want to create an executable file with various commands that run a project in django along with a virtual environment. The commands I want to run are:
d:
cd Python/projects
myvenv\Scripts\activate
cd web
python manage.py runserver

You can chain those commands like this in Windows machine:
Python\projects\myenv\Scripts\activate && python web\manage.py runserver

How to properly run virtualenv via .sh run script (django)

I am having an issue via an apache Nearly Free Speech server (I have been following the NFS guide via this link: https://blog.nearlyfreespeech.net/2014/11/17/how-to-django-on-nearlyfreespeech-net/. I have created a run-django.sh file to properly run the application which also opens a virtualenv (I have named the folder 'venv'). These are the contents of my run-django.sh file:
#!/bin/sh
. venv/bin/activate
exec python3 manage.py runserver
On the current step of the guide I am attempting to run the run-django.sh as follows:
[questionanswer /home/protected]$ ls
question_answer run-django.sh venv
[questionanswer /home/protected]$ cd question_answer/
[questionanswer /home/protected/question_answer]$ ../run-django.sh
.: cannot open bin/activate: No such file or directory
How is this not detecting my directory of 'venv/bin/activate' ?

Your version of Django requires Python 3, but it looks like python is python2, even after activating the virtual environment. You can use which python to check that python is pointing to the executable in your virtual environment.
If your virtual environment was created with python 2, then you'll have to create a new virtual environment that uses python 3.
deactivate
python3 -m venv /path/to/urban.new
source /path/to/urban.new/bin/activate
# install requirements

cannot open manage.py after installing django

I have a problem in setting up django.
My situation: I have Anaconda Python 2.7 in my Windows 8 computer. On the Anaconda command prompt window, I type: pip install django. This is successful.
Then I create a folder named "newproject". On the command prompt I went to the folder "newproject". Then django-admin.py startproject newproject. This is successful.
Then I run python manage.py runserver. It tells me
"...can't open file 'manage.py': [Errno 2] No such file or directory"
I checked out udemy django installation guide and other guides on the net. I have even set up a virtual environment. But the main problem is always: can't open file 'manage.py'

You're not in the proper directory...In the case you described, you should have:
mkdir newproject (not sure why you're doing this...but we'll continue with it)
cd newproject
django-admin.py startproject newproject
cd newproject ← A key missing part from what you did. You need to change into the directory where manage.py resides. Verify it by using ls at the command prompt after switching into the directory.
python manage.py runserver
Use ls often, if you need, to double check where you are in the directory tree.

You are not in the correct directory. You need to do cd newproject and the execute your runserver command.

For me it was because the manage.py didn't get created and the problem was that:
In windows instead of typing "django-admin.py" just type "django-admin" and it will create the manage.py file

you need to change your directory to the directory of the project.
open your environment by typing activate environment_name
change the directory to the folder in which you want to create the
project by cd Folder_Name
then create your project by django-admin startproject
Project_Name
then change the directory to your project folder
if you also want to create an app then typepython manage.py
startapp App_name
to confirm if it works type python manage.py runserver, then
you should get a link in the terminal. copy and paste that link in
the browser and you should see a successful page.

The reason of this problem is because you're in the first project directory "parent directory", and you have to go to your project "newproject" that has the manage.py file.
The way to this is simple:
cd "name of your project", E.g. cd newproject
python manage.py runserver

You need to include a . after you create the project.
Eg: django-admin.py startproject newproject .
This will allow you to run python manage.py runserver from where you are.

That can happen because manage.py doesn't have permissions.
Check the existence of manage.py throughout newproject, If exist you can fix it with:
$cd newproject
$chmod +x manage.py
Finally, try to execute python manage.py runserver

I was having the same problem, when Windows 10 changed credentials, Docker lost the access to drives. The fix for this issue, I reset the credentials in docker-desktop > shared Drives > reset credentials at bottom.

can't open file 'manage.py': [Errno 2] No such file or directory"
here is the solution
step 1: command -> django-admin startproject project_name
step 2: command -> cd project_name
step 3: command -> python manage.py startapp app_name
try it may fix your problem

You should navigate to the inner directory where your manage.py resides. For example:
If you have created projectname as
Django-admin startproject loginapp
Step 1: Go to loginapp
Step 2: Click on it
Step 3: You will find another loginapp and manage.py folder inside that
Step 4: Use this rootpath commandprompt
Step 5: Enter py manage.py runserver
Now it will work

I ran into the same error seller. But this is what I discovered
1: open your terminal in your project environment
2: install Django using: pip install django (if you are on windows)
3: then create your Django project using : django-admin startproject newproject . (django-admin start-project followed by project name give a space and add period (.) )
So it goes like this
django-admin startproject new project .
The period/fullstop (.) At the end tells djando the area in which the file should be created which is inside the project file its self you are working on. After this is done you are free to go. You can now run your server and enjoy
Run server using: python manage.py runserver

Make sure to put a period at the end of your command e.g
Django-admin startproject new project .
The period at the end (.) will solve the problem
