I downloaded pip and django with python -m pip install django, I also downloaded crycrs_forms but when I click to python manage.py runserver it crashes and doesn't run:
How can I fix it?
For better location of packages and files and better management, you should use virtual environments.
First create a folder (Django) and open it in vscode.
Then use the following command in the terminal to create a new virtual environment (.venv)
python -m venv .venv
After the command is executed, select the virtual environment interpreter in the select interpreter panel
Create a new terminal activation environment
Install django using the command in the new terminal
python -m pip install django
Create a Django project
django-admin startproject web_project .
Create an empty development database
python manage.py migrate
To verify the Django project, make sure your virtual environment is activated, then start Django's development server using the command
python manage.py runserver
I have downloaded anaconda and Django, but VS code shows
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?
so, I check out Get out of root conda environment and Problem with django after installing anaconda, installed django in virtual environment. Then follow https://docs.djangoproject.com/en/4.0/topics/install/. But I can't check out version by''' django-admin.py --version''' it shows command not found: django-admin
According to what you describe, I believe that you didn't activate the env or you don't have one in your directory, run this command py -m venv env && .\env\Scripts\activate then python -m pip install Django to create an env and activated and install Django if you have an env in your directory you need to activate using this .\env\Scripts\activate and then install Django finally run server Django using py manage.py runserver should works.
You're getting that error because you're calling django with the system's python and not the one inside your virtualenv.
Activate your virtualenv and then type:
python -m pip install django
That's it! Django will be recognized.
Also, when wanting to check django version, just simply do:
django-admin --version
without the .py piece
Remember to always call python inside your virtualenv. Let's say, like so:
python .\manage.py runserver
I'm following the Django tutorial https://docs.djangoproject.com/es/1.10/intro/tutorial01/
I've created a "mysite" dummy project (my very first one) and try to test it without altering it.
django-admin startproject mysite
cd mysite
python manage.py runserver
File "manage.py", line 14
) from exc
^
SyntaxError: invalid syntax
I'm getting a SyntaxError on a file that was generated by the system itself. And I seem unable to find anyone else who has gone through the same issue.
I'll add some data of my setup in case it may be of use
$ vpython --version
Python 2.7.12
$ pip --version
pip 9.0.1 from /home/frank/.local/lib/python2.7/site-packages (python 2.7)
$ python -m django --version

try:
from django.core.management import execute_from_command_line
except ImportError as exc:
raise ImportError(

"forget to activate a virtual environment?"
) from exc

Make sure which python version you connect the django with (Make sure to activate the virtual env if you are using any).
When you install django using just
pip install django
then you have to run
python manage.py startapp <yourApp name>
else if you have used:
pip3 install django
then you have to run
python3 manage.py startapp <yourapp name>
Refer:
You can try with python3 manage.py runserver.
It works for me.
You should activate your virtual environment.
In terminal, source env/bin/activate. Depending on your shell, something like (env) should now be a part of the prompt.
And now runserver should work. No need to delete exc part!
Just activate your virtual environment.
For running Python version 3, you need to use python3 instead of python.
The final command will be:
python3 manage.py runserver
I was experiencing the same but this was solved by running with specific python 3.6 as below:
python3.6 manage.py runserver
Its a simple solution actually one i just ran into. Did you activate your virtual environment?
my terminal screenshot
It's best to create a virtual environment and run your Django code inside this virtual environment, this helps in not changing your existing environments. Here are the basic steps to start with the virtual environment and Django.
Create a new Directory and cd into it.
mkdir test , cd test
Install and Create a Virtual environment.
python3 -m pip install virtualenv virtualenv venv -p python3
Activate Virtual Environment: source venv/bin/activate
Install Django: pip install django
Start a new project: django-admin startproject myproject
cd to your project and Run Project:
cd myproject,
python manage.py runserver
You can see your project here: http://127.0.0.1:8000/
After testing with precise instructions (using python2 or python3 instead of just "python") I've constated that no matter what the tutorial says, this works ONLY with python3.
The solution is straightforward. the exception from manage.py
is because when running the command with python, Django is unable
to predict the exact python version,
say you may have 3.6, 3.5, 3.8 and maybe just one of this versions pip module was used to install Django
to resolve this either use:
./manage.py `enter code here`<command>
or using the exact python version(x.x) stands:
pythonx.x manage.py <command>
else the use of virtual environments can come in handy
because its relates any pip django module easily to python version
create env with pyenv or virtualenv
activate (e.g in virtualenv => virtualenv env)
run using python manage.py command
I solved same situation.
INSTALLED VERSION
python 3.6, django 2.1
SITUATION
I installed Node.js in Windows 10. After python manage.py runserver caused error.
ERROR
File "manage.py", line 14
) from exc
^
SyntaxError: invalid syntax
REASON
My python path changed to python-2.7 from python-3.6. (3.6 is correct in my PC.)
SOLUTION
Fix python path.
The following could be the possible reasons,
1. The virtual environment is not enabled
2. The virtual environment is enabled but the python version is different
To create virtual environment
$ virtualenv --python=python3 venv
To activate the virtual environment
$ source venv/bin/activate
You must activate virtual environment where you have installed django.
Then run this command
- python manage.py runserver
Also, the tutorial recommends that a virtual environment is used (see Django documentation: https://docs.djangoproject.com/en/2.0/topics/install/#installing-official-release"). You can do this with pipenv --three. Once you've installed django with pipenv install django and activated your virtual environment with pipenv shell, python will refer to python3 when executing python manage.py runserver.
Pipenv documentation:
https://pipenv.kennethreitz.org/
Activate your virtual environment then try collecting static files, that should work.
$ source venv/bin/activate
$ python manage.py collectstatic
You should start your Virtual Environment,
How to do it?
First with terminal cd into the directory containing manage.py
Then type $source <myvenv>/bin/activate
replace with you Virtual Environment name, without angular brackets.
Another issue can that your root directory and venv mis-match.
The structure should be something like this:
|-website
..facebook
..manage.py
..myvenv
..some other files
That is your virtual environment and manage.py should be in the same folder. Solution to that is to restart the project. If you are facing this error you must haven't coded anything yet, so restart.
I had the exact same error, but then I later found out that I forget to activate the conda environment which had django and other required packages installed.
Solution: Create a conda or virtual environment with django installed,
and activate it before you use the command:
$ python manage.py migrate
The django-admin maybe the wrong file.I met the same problem which I did not found on a different computer the same set-up flow.
After comparing two project, I found several difference at manage.py and settings.py, then I realized I created 2.0 django project but run it with python2.
runwhich django-adminin iterm
/Library/Frameworks/Python.framework/Versions/3.6/bin/django-admin
It looks like I got a django-admin in python3 which I didn't know why.So I tried to get the correct django-amin.
pip show django
then I got
Name: Django
Version: 1.11a1
Summary: A high-level Python Web framework that encourages rapid development and clean, pragmatic design.
Home-page: https://www.djangoproject.com/
Author: Django Software Foundation
Author-email: foundation#djangoproject.com
License: BSD
Location: /Library/Python/2.7/site-packages
Requires: pytz
In/Library/Python/2.7/site-packages, I found the django-admin
/Library/Python/2.7/site-packages/django/bin/django-admin.py
So I created project again by
/Library/Python/2.7/site-packages/django/bin/django-admin.py startproject myproject
then run
cd myproject
python manage.py runserver
succeeded🎉
We have to create a virtual environment inside the project, not outside the project..
Then it will solve..
I landed on the same exact exception because I forgot to activate the virtual environment.
I was also getting the same error.
Then I went back to the folder where the environment folder is there and I forgot to activate a Virtual environment so only I was getting this error.
Go to that folder and activate the virtual environment.
$ source env/bin/activate
I had this issue (Mac) and followed the instructions on the below page to install and activate the virtual environment
https://packaging.python.org/guides/installing-using-pip-and-virtual-environments/
$ cd [ top-level-django-project-dir ]
$ python3 -m pip install --user virtualenv
$ python3 -m venv env
$ source env/bin/activate
Once I had installed and activated the virtual env I checked it
$ which python
Then I installed django into the virtual env
$ pip install django
And then I could run my app
$ python3 manage.py runserver
When I got to the next part of the tutorial
$ python manage.py startapp polls
I encountered another error:
File "manage.py", line 16
) from exc
^
SyntaxError: invalid syntax
I removed
from exc
and it then created the polls directory
Same issue occurred to me,But what I did was,
Just Replaced:
python manage.py runserver
with
python3 manage.py runserver
in the terminal(macOsX). Because I am using Python version 3.x
I encountered the same error when using pipenv. The issue was caused by not accessing Django correctly from within the virtual environment.
The correct steps using pipenv:
Activate virtual environment: pipenv shell
Install Django: pipenv install django
Create a project: django-admin startproject myproject
Navigate into project folder: cd myproject
Start Django with pipenv: pipenv run python manage.py runserver
Note: Pipenv will use the correct python version and pip within the virtual environment.
It seems you have more than one version of Python on your computer.
Try and remove one and leave the only version you used to develop your application.
If need be, you can upgrade your version, but ensure you have only one version of Python on your computer.
What am I wondering is though the django is installed to the container it may not be in the host machine where you are running the command. Then how will the command run. So since no above solutions worked for me.
I found out the running container and get into the running container using docker exec -it <container> bash then ran the command inside docker container. As we have the volumed container the changes done will also reflect locally. What ever command is to be run can be run inside the running container
For future readers,
I too had the same issue. Turns out installing Python directly from website as well as having another version from Anaconda caused this issue. I had to uninstall Python2.7 and only keep anaconda as the sole distribution.
Have you entered the virtual environment for django? Run python -m venv myvenv if you have not yet installed.
I had same problem and could solve it. It is related to the version of Django you've installed, some of them are not supported by python 2.7. If you have installed Django with pip, it means that you are installing the latest version of that which probably is not supported in python 2.7, You can get more information about it here. I would suggest to python 3 or specify the version of Django during installing (which is 1.11 for python 2.7).
I solved this problem to uninstall the multiple version of Python.
Check Django Official Documentation for Python compatibility.
"Python compatibility
Django 2.1 supports Python 3.5, 3.6, and 3.7. Django 2.0 is the last version to support Python 3.4."
manage.py file

If removing "from exc" from second last line of this code will generate another error due to multiple versions of Python.

What i should to do?
To begin using the virtual environment, it needs to be activated
source venv_path/bin/activate
this will help you
for more details this will help you
Simple way is to make a virtual environment first & activate it and then make your project and App in its enviroment.
Follow the Following Steps to go through a less error routine:
Python -m venv newms
source newms/bin/activate
pip install django
django-admin startproject projectName
cd projectName Then python manage.py startapp appname
Here you're basically creating virtual env named newms and activating it then install django and then you can go ahead and make your project and apps inside it.
I went through all the solutions but none of that resolves my issue. So while trying to create project using the startproject command on command line. I am getting an error.
Here is the series of steps that I have tried
1. Installed Python
2. Installed Django
3. django-admin startproject mysite
which gives me an error
CommandError: [WinError 2] The system cannot find the file specified: 'C:\\Users\\Himanshu Poddar\\Desktop\\mysite'
However django-admin is working fine though, which gives me a list of Django commands.
My Django version is 2.1.2 and I am using Win10.
Edit
The command is working when I changed my directory to C:\Users\Himanshu Poddar and the file is successfully created but when I am trying same in any other directory I am getting an error.
I experienced same issue. And it turned out to be issue regarding the python.exe file name.
I created virtual environment for python 3.6 and in the envs/env_name folder the name of the file was python.exe instead of python3.exe
So I copied the python.exe file in same folder and renamed it to python3.exe. Now I can access the python using both python3 and python commands in command prompt.
For Windows:
To run django-admin command you need to activate python virtual enviroment.
To create virtual enviroment
python3 -m venv venv
Then activate by
venv\Scripts\activate
Then run
django-admin startproject mysite
ALternative way:
Installing virtualenv through pip
pip install virtualenv
Then create venv by
virtualenv venv
and activate by
. .\venv\Scripts\activate
I experienced this same issue and found the culprit (at least in my case): Windows 10 ransomware protection, specifically the controlled folder access setting. Turning that setting off and running "django-admin startproject mysite" allows the folder to be created. I turned controlled folder access back on after running the command.
