I'm new to django and currently going through the main tutorial. Even though it was working earlier, when I do python manage.py runserver OR python manage.py -h OR with any other command, the shell doesn't output anything. Wondering what I'm doing wrong.
The problem is that the first line in manage.py breaks the file on windows.
The first line should look like this:
#!/usr/bin/env python
Removing it will fix the issue.
First, check if python is fully installed by typing "python" in a shell.
Then you should try python manage.py runserver inside your django project. If you don't have any django project, try creating one by typing django-admin.py startproject mysite. If nothing is displayed in your shell, you must have installed Django the wrong way.
Please refer to Django Documentation at https://docs.djangoproject.com/en/1.4/intro/install/
If you had your server running till one point and a certain action/change broke it, try going back to the previous state.
In my case there was an email trigger which would put the system in an invalid state if email doesn't go through. Doing git stash followed by selectively popping the stash and trying the runserver helps narrow down the problem to a particular file in your project.
Please try this.
Uninstall Python.
Go inside C drive and search Django. You will get many Django related files.
Delete every Django file. đ don't delete your Django files.
Install Python.
It's worked for me.
if you created a virtual environment then activate it. you can try this command(in virtual environment directory) if you're using windows os:
.\Scripts\activate
On Ubuntu works for my by running manage.py as script:
./manage.py runserver
Just stuck with the same problem. Found a solution that works, but tedious.
You need to know the location of the python.exe file in your computer. It is usually
C:/Users/USERNAME/AppData/Local/Programs/Python//python.exe
Modify as required and run the following in CMD,
C:/Users/USER1/AppData/Local/Programs/Python/Python38-32/python.exe
F:/mysite/manage.py runserver
Hope this works :)
if you are using Redis Server on Windows, check it out if Redis Server is running, I had same problem and realized my Redis Server was not running, I ran it and now my manage.py commands work fine.
The same happened with me also, but this issue is a minor one as it happens if you have multiple versions of Python on your system, you can select a specific Python version by running python3 or whichever version you want.
SO you should start from the beginning, uninstall Django first then,
create a virtual environment, decide upon a directory where you want to place it, and run the venv module as a script with the directory path:
for e.g:
python3 -m venv tutorial-env
//This will create the tutorial-env directory if it doesnât exist, and also create directories inside it
Once youâve created a virtual environment, you may activate it.
On Windows, run:
tutorial-env\Scripts\activate.bat
On Unix or MacOS, run:
source tutorial-env/bin/activate
Now,
In the command prompt, ensure your virtual environment is active, and execute the following command:
...> py -m pip install Django
NOTE:
If django-admin only displays the help text no matter what arguments it is given, there is probably a problem with the file association in Windows. Check if there is more than one environment variable set for running Python scripts in PATH. This usually occurs when there is more than one Python version installed.
Another solution, if you can, is to upgrade Django
pip install django --upgrade
Oftentimes one will get other unrelated issues to solve that are linked with the upgrade but once all is fixed the server should run just fine.
If you can't upgrade Django, this problem also happens when the code was built using Python 2.x and you're locally using Python 3.x.
The quicker fix in that case is to uninstall Python 3.x from your machine and make sure Python 2.x was added to the path. I've seen some developers setting up alias in PowerShell to have more than one version in the environment too.
I think the problem is in manage.py file (50%), check it with an another file that is correct.

It's been a while since I posted anything here, and now my problems have become more advanced. For reference, I'm running on Win10.
I'm trying to use the Django framework. Python's been installed on my computer forever; it's the latest version, and it's installed on environment variables/added to system paths. I think those are enabled by default, but I did make sure that they were checked when I reinstalled it.
pip's been updated too. Django installed successfully. I managed to get all the way to installing my new project with django-admin startproject PROJECTNAME, but when I try to run python3 manage.py runserver, I'm getting this error:
Python was not found; run without arguments to install from the Microsoft Store, or disable this shortcut from Settings > Manage App Execution Aliases.
This "Python was not found" error is the main problem that I'm trying to figure out. Nothing I do as a fix seems to get rid of it.
...Interesting. If I type in python --version, I get a response (Python 3.11.0). Here's what I get if I do pip freeze:
asgiref==3.6.0
Django==4.1.6
sqlparse==0.4.3
tzdata==2022.7
Python IDLE runs fine; all .py files run fine. Alright. So, with that in mind and in accordance to a lot of popular advice I've seen floating around, I added the Path to my Environment Variables. For space-saving reasons, my Python is installed on my D drive rather than C. I've made sure that there weren't any leftover Python files that conflicted.
I've uninstalled and reinstalled, double checked my installations, and Django is in D:\ProgramData\Python311\Scripts with pip and everything else I need. I did also disable the shortcut from Settings > Manage App Execution Aliases, but when I did that, I got this error:
python3 : The term 'python3' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again.
Based on some other things I've seen, I've also tried:
python manage.py runserver
python3 ./manage.py runserver
I ended up having to enable the options again just to use Python correctly. And I have been closing and reopening the command line whenever I make changes. Though it updates automatically to fit what I've been doing, I wanted to make sure I didn't overlook any possibility.
I even uninstalled Django for a third time, installed the virtual environment (which I realised I skipped), and did it all again. And then, after a long series of figuring out how to activate the virtual environment and enabling scripts to run, I'm finally in (venv) D:\PROJECTNAME, and I tried... to run it again.
I'm still getting the Python not found error. orz
I've been at it for two hours or so, and I feel like I'm running into a dead end. I think I've finally met my match here.
This is my first time using frameworks like this, and it's been a while since I've installed anything through command line on Windows. I'm not very great at this, so I know that I'm making some amateurish mistakes somewhere. Please let me know if I'm doing anything wrong or missed something obvious.
Please.... I just want to use Django....
Thanks in advance!
This question really is not proper for a PowerShell Q&A, but let see if the below helps.
If you are trying to run django from PS, then:
pip install django
django-admin startproject YourProjectNamehere
lastly, hit your dev server
HTTP://YourDevServerName:YourDevServerPortNumber
Also, be sure that you've activated your virtual environment, never assume it is until you test it. Of course, be sure to change directly to the root of your project.
Again, if you are using python, directly, then, it's more prudent to stay in your pristine python shell vs executing from a PowerShell consoler/terminal, thus eliminating any PowerShell particulars.
first download manually python on your computer , therefore install django from official website , www.python.org/downloads/, https://www.djangoproject.com/download/,
if you're on linux, pip install Django==4.1.6
after installing that use ,
django-admin
I sincerely apologize for the noobish dribble thats about to come out here:
Okay so I am following along with a youtube tutorial using terminal/django/komodo edit to make a simple website. This is my first time really using terminal, I am having issues. I have read up on the terminal and searched this site for my question but to no avail. Im hoping someone will take the time to answer this for me as it is most infuriating. This is my first time working with virtual env's as well.
So my question is, How do I uhmm, I suppose "save" my virtual env settings?
So I have set up a new virualenv. Downloaded django and started up my server so I can see things such as the admin page, log in page, from the internet page. Things go as they should along with the tutorial until it comes time to eventually turn off my computer.
When I reload the virtualenv I cannot run the server, it gives me: Import error, no module named django.core.management.
I use pip freeze and it shows that django is no longer installed.
If trying to reinstall django it gives a long block of error messages.
All the work done within the virtualenv file is still visible for the komodo edit pages however, but it seems the terminal does not want to work properly. My only option thus far has been to completely remake a virualenv, re-set it all up with the proper imports, files, django and restart the project.
so my questions are:
how do I save my terminal and/or virtualenv settings?
What do I need to do before logging off to ensure I will be able to continue with my project?
Lets say I am going to continue with my project, How do I start up the project again via terminal? Is that where I am going wrong? I've assumed up until now that I must go into terminal, start the server again and then from komodo edit continue with my project, but inside the terminal everything goes wrong.
Im not even explicitly saying I cannot continue with my project, I am more saying the terminal is not recognizing I had django installed within my virtualenv, and it is not letting me start the server again.
I have tried doing the research on my own, I am not one to sit back and wait for an answer but being completely new, this is baffling. I am sorry for the noob questions, feel free to link another answered question or website that has the answer.
Thank you all!!
Let's start from the beginning:
You are in your project folder eg /home/me/myproject
You create a new virtualenv, eg virtualenv /home/me/virtualenvs/myprojectenv
You activate the new virtualenv:
source /home/me/virtualenvs/myprojectenv/bin/activate
...this means that python and pip commands now point to the versions installed in your virtualenv
You install your project dependencies pip install django
You can ./manage.py runserver successfully
Now, the virtualenv has only been activated in your current terminal session. If you cd outside your project directory the virtualenv is still active. But if you open a new terminal window (or turn off the computer and come back later) the virtualenv is not activated.
If the virtualenv is not activated then the python and pip commands point to the system-installed copies (if they exist) and Django has not been installed there.
All you need to do when you open a new terminal is step 3. above:
source /home/me/virtualenvs/myprojectenv/bin/activate
Possibly the tutorial you followed got you to install virtualenvwrapper which is an additional convenience layer around the virtualenv commands above. In that case the steps would look like this:
You are in your project folder eg /home/me/myproject
You create a new virtualenv, eg mkvirtualenv myprojectenv
...virtualenv has already been activated for you now!
You install your project dependencies pip install django
You can ./manage.py runserver successfully
and whenever you start a new shell session you need to:
workon myprojectenv
in order to re-activate the virtualenv
I'm following along with the djangoproject.com tutorial. I used pyCharm to setup a dummy project.
on my terminal command line I cd into the folder that has manage.py i then run the line.
python manage.py startapp polls
I get this error:
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.core.management
What is this and why can't I create another app called polls?
In my case, I already have installed Django, but I type "runserver" command from virtualenv and it showed the same error that Chapsterj
I resolved typing this:
(venv)$ pip install Django
Before, To enter in virtualenv, type this:
$ virtualenv venv --distribute
$ source venv/bin/activate
(venv)$
I've never heard of PyCharm, but as the comments suggest, this means the python interpreter cannot find django.
One thing to try - open up a terminal (anywhere) and type:
python
then run
import django
If you have django installed, this should work; otherwise it will not.
In my case, I run all of my django installs via virtualenv (basically, localised versions of the python package index so different projects can have different versions of packages installed) so doing this from any old terminal for me doesn't work.
In my case, I then need to make an adjustment to the PYTHONPATH environment variable. Well, actually, I'm lying slightly, virtualenv is a little more complicated than that, but that's another way to make it work.
So, I would suggest:
Making sure you have django installed in your python site-packages directory (where most third party packages live). Usually, something like yum install python-django or pip install Django will do this for you.
If this is not where you've installed Django, edit your PYTHONPATH first in a shell session (to make it easy to test and get right) and then in your IDE so python can find it.
If the IDE doesn't provide you with a way to edit the pythonpath variable, you should be able to manage this by editing manage.py like so:
import sys
sys.path.append('/opt/Django')
# the rest of manage.py ...
import django
To properly install django you must use the "superuser", try
sudo pip install django
Hope it helps
On Rhel6, umask prevented the django directory from being accessed, so I had to run:
cd /usr/lib/python2.6/site-packages/django/
find django -type d | xargs chmod 775
find django -type f | xargs chmod 664
and add /usr/lib/python2.6/site-packages/django/ to my path in .bash_profile.
I see no accepted response to this and since it is not so much a Django question as it is a PyCharm question, I'll add my 2c in case others are having the same problem getting started.
I am also running through the "Writing your first Django" tutorial using PyCharm and I am not having these problems. I WAS having all sorts of problems until I realized that you let PyCharm create everything and the problems go away ;-)
So far, I am reading both the PyCharm AND the Django tuts together. PyCharm tut is here: https://www.jetbrains.com/pycharm/help/creating-django-application-in-a-project.html
YOUR problem may be answered with this:
To add a new django application to an existing project
On the main menu, choose Tools | Run manage.py task
In the Enter manage.py task name dialog box, type startapp. Note suggestion list that appears under the dialog box after entering the first letter, and shrinks as you type to show the exact match only.
In the dialog box that opens, type the name of the new Django application.
I had a same problem with PyCharm, what I did was:
Go to File -> Default Setting ->
Project Interpreter (Pick python 3...) if thats what you want to use
It will show all packages available
Double click on Django
Install Package.
Then in terminal instead of
python manage.py migrate
tape
python3 manage.py migrate
I have installed django on my windows vista computer and can add the django library to a python script, but cannot seem to ge teh following to work correctly from the command line:
django-admin.py startproject mysite
When I try to run this or the help command I always get the default message that shows all the commands as if I did not send it the second argument.
Any ideas on how to resolve this issue?
try
python django-admin.py startproject mysite
you may cd to the dir which the django-admin.py in
The biggest headache I've run into with developing on Windows is path issues. I use virtualenv and David Marble's port of virtualenvwrapper As such, I fully qualify the path to django-admin.py. Of course, the virtualenv's site-packages could get added to my PATH, but I find it just as easy to just paste in the path.
Try fully qualifying the path to django-admin.py and see if that gets you going.
If python variable environment is set you should try something like
python Path\to\django\installation\bin\django-admin.py startproject mysite
FYI, I figured out the issue based on another thread I found here:
Windows is not passing command line arguments to Python programs executed from the shell
The issue was about how the registry was handling my calls to admin.py and the fact that it was dropping the arguments I passed.
Hope this helps others who run into this issue.
I have a Windows box with cygwin, python and django installed.
Now I want to run django-admin, but when I do I get the error:
$ django-admin.py
c:\Python26\python.exe: can't open file '/usr/bin/django-admin.py': [Errno 2] No such file or directory
From here
For Windows users, who do not have symlinking functionality available, you can copy django-admin.py to a location on your existing path or edit the PATH settings (under Settings - Control Panel - System - Advanced - Environment...) to point to its installed location.
hope this helps
I just ran into the exact same problem. I've found that if you already have the windows version of python installed, it seems to get priority over the cygwin version. I solved the problem by editing /etc/profile and changed:
PATH=/usr/local/bin:/usr/bin:/bin:/usr/X11R6/bin:$PATH
...to:
PATH=/usr/local/bin:/usr/bin:/bin:/usr/X11R6/bin:
...which I think stops cygwin from adding the normal windows path. Once you've got that working, download django into some directory, move into that directory and type:
python setup.py install
I was having problems to begin with because I had omitted the 'python' bit at the start
As for the step on how to start your django in cygwin
first open your windows command prompt
then register the python environment by doing this:
Path %path%;C:\Python27;C:\Python27\Scripts
then now go to the installation folder of your cygwin
cd C:\cygwin
then run the cygwin.bat like this:
C:\cygwin>cygwin.bat <enter>
then cygwin will open, and type python to see if it now working
$ python
Voila we are done!
Sort of sounds like the windows version of Python is trying to run instead of the cygwin one. What happens if you type this:
$ python django-admin.py
Here I'm assuming
$ which python
Finds the cygwin version of python (which will be something like /usr/bin/python).
You may also try (temporarily) uninstalling the windows version of python and use only cygwin.
Help us help you. Is there a reason why you are running the windows python interpreter (c:\Python26\python.exe) as oppose to the cygwin python interpreter (/usr/bin/python.exe)? That could be your problem. So to troubleshoot that, you might consider removing the windows native interpreter or simply making sure the cygwin path is listed before the c:\Python26 path in the windows global PATH variable.
Add the location of your django/bin folder (or wherever else you keep django-admin.py) to your PYTHONPATH environment variable.
Like Brian mentioned you are running the Windows version of Python which won't work with the Cygwin installation.
A word of warning. When I first started using Django, I tried installing it in Cygwin and had a variety of problems and ended up switching to the regular Windows version of Python. Unfortunately, I didn't document all my issues, but I remember some of them had to do with the database libraries. Anyway, that was a few months ago when I knew less about Django than I do now. Maybe the problems I ran into have been solved and perhaps now that I know more I could get it to work, but running Django on Cygwin does seem to be the road less traveled. Good luck. :)
Just copy the django-admin.py to the current location you are working on for e.g
on Cygwin:
<root>/projects/
on your windows directory it will look like this:
C:\cygwin\home\<your computer name>\projects\
once you copy the file, you can create your project by typing this command:
$ python django-admin.py startproject mysite
and that's all - you have completed your first project using the Cygwin linux-like environment.
Add two lines to .bash_profile and .bashrc files (view their difference here). You can find them in C:\cygwin\home\[username]:
export PATH=$PATH:/cygdrive/c/python2.7
export PYTHONPATH=$PYTHONPATH:/cygdrive/c/python2.7/Lib/site-packages
Hope this helps
