Django development server won't run - python

I'm using Python 3.4.2 and Django 1.7.1
I've been able to create a folder called mysite with its content like shown in the tutorial.
But when I run the command manage.py runserver nothing happens:
C:\Users\thEpuQ8f\Dropbox\zephyrus>manage.py runserver
I get following message in the command line:
Usage: manage.py subcommand [options] [args]
Options:
-v VERBOSITY, --verbosity=VERBOSITY
Verbosity level; 0=minimal output, 1=normal output,
2=verbose output, 3=very verbose output
--settings=SETTINGS The Python path to a settings module, e.g.
"myproject.settings.main". If this isn't provided, the
DJANGO_SETTINGS_MODULE environment variable will be
used.
--pythonpath=PYTHONPATH
A directory to add to the Python path, e.g.
"/home/djangoprojects/myproject".
--traceback Raise on exception
--no-color Don't colorize the command output.
--version show program's version number and exit
-h, --help show this help message and exit
Type 'manage.py help <subcommand>' for help on a specific subcommand.
Available subcommands:
# and so forth

You probably don't have the correct PYTHONPATH.
You know what has worked for me really well on windows.
My Computer > Properties > Advanced System Settings > Environment
Variables >
Then under system variables I create a new Variable called PythonPath.
C:\Python34;C:\Python34\Lib;C:\Python34\DLLs;
Where Python34 is the folder of the Python. I don't know what's the correct folder name for python3. When you install the Python with installer, it should create PYTHONPATH automatically. So worst case scenario is that you just reinstall it.

Try this command:
python manage.py runserver
Adding python in front of your command will run your python file.
If it produces errors, then make sure that python is installed and python install dir is listed in your PATH environment variable.
When it runs, try opening this URL in your web browser of choice to see if it works.
Then you should see a page like this:

Cron fails with the message Superset: command not found

I've installed Superset following the installation guide in the apache superset web page, for Python 3.7.
Even though I can manually start the server, when I'm trying to script the startup steps and cron them, it fails.
The output of the execution is the following:
superset: command not found
I've read the replies of this topic but nothing applies to this case.
I'm not using virtualenv for the installation.
These are the output of the which commands:
ec2-user#Superset-STAGE /var/spool/mail$which python3
/usr/bin/python3
ec2-user#Superset-STAGE /var/spool/mail$which superset
~/.local/bin/superset
ec2-user#Superset-STAGE /var/spool/mail$sudo superset
sudo: superset: command not found
Would you please guide me on how to have my script working without failure? Script looks like below.
superset init
wait
superset runserver -d
Cron runs as root, which means its home directory is /root rather than /home/ec2-user as you expect. This means that it will not be able to find /home/ec2-user/.local/bin/superset because it neither looks for executables in a ~/.local/bin/superset nor is it logged in as a user that has such a directory. A quick fix here is to use the full path, but I would recommend moving the executable to a more appropriate directory such as /usr/local/bin and then adding it to the PATH variable in /etc/profile

I can't open manage.py

On the command prompt, (Windows 10) I created a virtual environment, I then created a new project, I installed django in the virtual environment using pip. Then decided to run the command
python manage.py runserver
To run djangos web server,
This returned with
"...can't open file 'manage.py': [Errno 2] No such file or directory"
I did see a similar question to this on this platform but it seems to only apply to those using linux. Where answers specify to use the ls command, which is not applicable on Windows command prompt. I have tried this multiple times but i just can't open
manage.py
When running a command on the command prompt, it is necessary to provide the correct path to the file.
Let's pretend you have your django files stored in a folder with the following path:
C:\my_stuff\subfolder\django_project >
Presume that when you run the dir command (the Windows analog to the ls command you mention in your question) it might show something like this:
C:\my_stuff\subfolder\django_project > dir
blog
db.sqlite3
manage.py
mysite
If you were to then run your command:
C:\my_stuff\subfolder\django_project > python manage.py runserver
Everything should work fine. But if you are in a different directory, you will get the error you describe. For example, this will fail.
C:\my_stuff\subfolder > python manage.py runserver
If, for some reason, your Windows command prompt does not show you which directory you are in, you can run the cd command to confirm where you are.
An alternate method is to point the python interpreter to the location of the manage.py script, by providing the path:
C:\my_stuff\subfolder > python django_project\manage.py runserver
But this sometimes introduces subtle problems, because scripts like manage.py might be written with the expectation that they will be run from the directory they are stored in. Your mileage may vary.

Django /manage.py runserver doesn't work (Windows)

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 Panel\System and Security\System
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.
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:\WINDOWS\System32>
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:\yourfolder\yourproject>
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

django-admin.py is not working

Am new to django and i have been trying to set up a project with no success. When i type
django-admin.py startproject mysite i get this.
C:\Users\WASSWA SAM\Documents\django\djcode>django-admin.py startproject mysite
Usage: django-admin.py subcommand [options] [args]
Options:
-v VERBOSITY, --verbosity=VERBOSITY
Verbosity level; 0=minimal output, 1=normal output,
2=all output
etc....
I have added it to my path like so
C:\Python26\Lib\site-packages\django\bin
And when i import django from interactive mode it works perfectly. What could be the problem. I am using Windows 7 and django 1.3.1. I installed it using setup.py.
I had the same problem; I found a working solution at https://groups.google.com/forum/#!msg/django-users/b76qSG3mV6g/jP1o0ny3i2kJ:
python C:\Python27\Scripts\django-admin.py startproject mysite
This is an error with Python's installation on Windows. If you have the regkey entry
HKEY_CLASSES_ROOT\py_auto_file\shell\command\open\
change the value from
"C:\Python27\python.exe" "%1"
to
"C:\Python27\python.exe" "%1" %*
(Or your equivalent installation location)
This ensures that command-line arguments are passed onto python, rather than explicitly ignored. This is fixed in the latest install of Python 2.7. %* is argv[]. "%1" is the script's absolute path.
I had the same problem and could not solve it for hours. Create a new project from Pycharm or any other program you are using, install Django and then instead of running
django-admin.py startproject *project_name* .
run
django-admin startproject *project_name* .
Ommiting .py extension worked for me and everything is running as expected now.
I don't think you need to have django\bin in the path.
I think what you need to add to your PATH though is C:\Python26\scripts and then you should be able to run the startproject script.
In my case, I use eclipse and you can start an eclipse project from within the eclipse environment using PyDev.
Go up to File > New > Other > (within the PyDev Folder) > PyDev Django Project. In the wizard it will allow you to setup most of the commonly used features of Django.

Can't open file 'django-admin.py': [Errno 2] No such file or directory

I'm using Python 2.7, Django 1.2.5 and on Windows 7.
I am not sure what I've done. I used to be able to create Django projects like
python django-admin.py startproject test
Now however I get this error.
Can't open file 'django-admin.py':
[Errno 2] No such file or directory
I can type the following which works.
python C:\Python27\Scripts\django-admin.py startproject test
How can I have it the way it used to be? Not having the type the full path to the django-admin.py file.
Things I've already tried:
I uninstalled Python and manually removed the values from the PATH variable in Windows. Reinstalled Python. Deleted Django and reinstalled it too.
I've added C:\Python27\Scripts to my PATH and PYTHONPATH variable under Environmental Variables in Windows.
Any suggestions?
My PATH variable contains
C:\Program Files (x86)\NVIDIA Corporation\PhysX\Common;C:\Program Files (x86)\ActiveState Komodo Edit 6\;%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;%SYSTEMROOT%\System32\WindowsPowerShell\v1.0\;C:\django-apps;F:\My_Projects;C:\Program Files (x86)\QuickTime\QTSystem\;C:\Program Files\TortoiseSVN\bin;C:\Program Files\Mercurial\bin;C:\Python27;C:\Python27\Scripts
PYTHONPATH has
C:\Python27;C:\Python27\Lib;C:\Python27\DLLs;C:\Python27\Lib\lib-tk;C:\Python27\Scripts;C:\django-apps;f:\my_projects
I had this same problem with slightly newer versions of Python 2.7.x and Django - and it is not the PATH. This is all I had to do to fix it in Windows XP:
Find a .py file (any, even a blank).
Right click on it and choose: "Open with>" and then select "Choose program...".
This pops up a list of all programs - select python, and check the box "Always use the selected program to open this kind of file" and then click OK.
Checking this box resets file associations and fixes this problem for the command line.
The cause of the problem: Telling Windows to open up .py files in a text editor as default.
If C:\Python27\Scripts is in your Path, just type in:
django-admin.py startproject proj
There should be a file association with .py and try to execute. If you prefix with python the next command is a file path.
I've never been able to do python django-admin.py -- I get the same error you describe.
Make sure python is associated with .py. You can check via file properties (opens with...) or typing assoc .py in cmd.
Here is what I did to get this working:
Installed Python 2.7 to C:\Python27 using the install package for Windows at python.org
I chose to install the latest release version of Django (1.3) (not the development trunk)
Installed Django following the instructions here: http://docs.djangoproject.com/en/dev/topics/install/
I'm only doing local development, so I skipped install of Apache and mod_wsgi (as directed in Django instructions)
I don't need a database for my app, so I skipped "Get your database running" section in Django instructions; and I skipped "Remove any old versions of Django" (didn't have any installed)
I skipped down the instructions to "Installing an official release"
I installed bsdtar as directed in order to untar the release files on my windows machine - ran no problem.
Being on Windows, I started a cmd shell with admin privileges and ran the command "setup.py install" - ran no problem
I followed the instruction to verify Django install: running import django and django.print get_version() - returned 1.3, success
Then it came time to run django-admin.py startproject myproject - I received similar errors to the above, and when trying to run django-admin.py from within the python interpreter, I received syntax errors pointing at the arguments. Strange.
Found this thread, and ran this, which worked: c:\Python27\Scripts\django-admin.py startproject myproject and it worked.
Still curious, I wanted to see if I could make it work from cmd prompt, without the paths, since it seemed that should work - and it didn't.
This is what I did beyond the install instructions that made it work for me on Windows:
Verified the file associations, using info from this post - all associations good.
Used Start|Computer|System Properties|Advanced System Properties|Environment Variables dialog to set the environment variables as follows:
Set New System Variable: PYTHONPATH = c:\Python27\Lib;c:\Python27\Scripts
Edit existing User variable: PATH added: C:\Python27;C:\Python27\Scripts to the end.
The result:
.py files now execute from cmd command line (no need to run python interpreter first)
e.g. the command django-admin.py startproject mynewproject ran just fine.
Please post any questions in the comments, maybe I can help.
Is it possible you associated your .py files with another program (like a text editor)? I had this problem, too, after associating .py files with gedit.
I'd have the problem if I did this:
python django-admin.py startproject myproject
Once I reassociated .py files to python this problem went away.
Gosh! It drove me crazy! Just do the following!
python C:\python27\scripts\django-admin.py startproject mysite
The problem seems to be with the file association. After adding the PATH variables, remove all "py" associations instead of linking them to your Python executable:
Remove the file type ".py " from the registry or by using a small
free tool for Windows Vista/Windows 7 called 'Unassoc' (google for Windows 7 unassoc).
In my case simply unassociating the file type was not enough. I had to remove the file type entirely using the unassoc tool.
Now you should be good to go.
I've solved it! It's the command line to open a file .py.
It has to be like so:
"C:\Python27\python.exe" "%1" %*
mine was:
"C:\Python27\python.exe" "%1" without the final %*
I've used FileTypesMan to edit because Windows 7 can't edit this property.
In my case it was solved by adding the path to django-admin.py.
The instruction in windows with a python 7 and django 1.11 is:
python c:\Python27\Lib\site-packages\django\bin\django-admin.py startproject mysite
First, set the path in PowerShell (in your $profile) like this:
$env:PATH = "C:\Python27\;C:\Python27\Scripts;c:\python27\lib\site-packages\django\bin\;"
Then, to get .py files to open in PowerShell rather than cmd, add this line:
$env:PATHEXT += ";.py"
Finally, to be able to just type "django-admin" and have it work, add this line:
function django-admin {python (gcm django-admin.py | resolve-path) $args}
That should do the trick.
After I installed an IDE, I had a similar (if not the same) problem. Sure enough, the .py "Open With" setting had been changed, and changing it back to the Python Launcher for Windows did the trick.
On Windows, I used
django-admin startproject test
and it seemed to have worked.
Since the path is too long, I moved the folders to a shorter path inside C: /. This way I call it faster, there is a problem with the route. I use Windows 10 with Django 3.0.5, so it turns out like this: python C:\Python38\Scripts\django-admin.py startproject test
The problem for me was the installation of Visual Studio.
I tried to install django-admin, which is usely automatically set up:
pip3 install django-admin
and it gave to me :
error: Microsoft Visual C++ 14.0 or greater is required.
So, I install Microsoft Visual Studio, and then it works.
Make sure that you cd is where you saved your Notepad++ Python file. If you saved it under your \Python27\ directory, then while in the terminal or PowerShell window, type cd C:\Python27 and press enter.
This will open that directory so when you type python filename.py it will find it and run it. Just remember to save all .py files to the same directory, so you have no further problems.
No Windows, usei:
python -m django startproject mysite
