ImportError when using heroku for my django web

I checked django is installed properly and in my 'requirements.txt' I wrote 'Django==3.2.3'. However, I cannot use this code:
heroku run python manage.py migrate
So I checked this code:
python manage.py migrate
and found out it worked properly. I know that there are existing questions and read many of them, but I think I have tried everything I could do. I would be really grateful if someone can solve this problem.
your question isn't clear tbh.
install all the dependencies by using the pip freeze command and try to run your heroku commands in the heroku bash available in your heroku dashboard
to run the commands on your heroku machine from your CMD, then command is
heroku run bash --app your_app_name
then you can run whatever command you want.
but I am not sure what is the exact problem you are having.

Python manage.py startapp does not work

When I run the python manage.py startapp "app name" command in my Django project directory nothing happens... Every other manage.py command works without problem.
What could be the problem?
Thanks a lot!!
Andrew
The first line in manage.py breaks the file on windows. The first line should look like this:
#!/usr/bin/env python
Removing it fixes the issue for me. Please try this is really helpful. Thanks
This problem occurs due to Python Path is not set, you can reinstall python and check the box that says "Add to Path 3.9"
Are you running the correct version of Python and correct version of Django?
To check Django:
python manage.py --version
Make sure you are running the right versions, if you are have Python 3 and Python 2 installed you may have multiple versions of Django.
Try to set environment variables on the command line? This path is if you were using vagrant.
PYTHONPATH=/vagrant/www DJANGO_SETTINGS_MODULE=settings django-admin.py startapp
Then try manage.py does it work? Without setting envs on the command line?
Adding a virtual environment is necessary to get the above command working. In the virtual environment you can specifically install Django and it is done so as to ensure that no other package interfers with the Django framework. I was also facing the same issue but after creating a virtual environment, things became super easy!!!
I would recommend using pycharm as creating a virtual environment is just as easy as running a hello world program!!. Also paste the following code at the settings.py script at the end :
ALLOWED_HOSTS=['*']
Also specify the correct directory while running in the terminal. Be sure to check that the code should be written inside the project directory.
Hope that helps :)
I was facing a similar issue and saw this question. Tried the methods mentioned by some of the users but it did not work. Surprisingly the only thing I had to do was remove the word "python" from the command. All I typed in the command line was - manage.py startapp "appname"
I have no idea what difference does it make or how I made it work, but if anyone has a similar problem I hope your issue gets resolved.
I think it maybe because i had previously added the directory I am working in the PATH variable. Not sure. Someone has an opinion on this, do share.
I think i may have found the solution. If you're running on python 3.7 or above, try setting your directory to ~\YourProjectName\YourProjectName with the cd commmand then type py -m django startapp <appName>
The command
$ python-admin startapp main
returns the error " bash: python-admin: command not found".
I was able to resolve using the following command instead
$ py -m django startapp main
if some of you are following old tutorials on django then after you have python version 3.7 or above then the command "python manage.py startapp 'appname'" doesnt works.//well it didn't work for me so insted of that command you can use "py -m django startapp 'appname'"
it worked for me so you can also try that..
the command -> manage.py startapp 'appname'" works for python version upto 3.7 and for 3.7 and above version used command -> "py -m django startapp 'appname'" it works for me...

celeryd-multi command unknown when using Django/djcelery

I'm using Django with Celery with the installed app djcelery. I'm trying to start multiple workers on the command line. I can run python manage.py celeryd without any issues. Everywhere, including Celeryd Docs, says that the command is celeryd-multi to start multiple workers. I try to run python manage.py celeryd-multi and I get Unknown command: 'celeryd-multi'. Why am I getting this error?
Running python manage.py help will show under the djcelery section a celeryd_multi option. The correct syntax is a _ instead of - (this may just be when using djcelery). If you need more information use python manage.py help celeryd_multi.

PTVS Django Data Base Migration

Im testing Python Tools For Visual Studio, I create a django project, make a SyncDB and install django admin with no problems, but now Im trying to make Data Base migration like: Django 1.7 Migrations. the point is that i cant figuer out how to do that. I serched in google and find this: How to run django database migrations with PTVS?. So the migration command is not wraped. I tried using Windows Command Prompt and install C:\Python34\;C:\Python34\Scripts; PATHS but when i type a django command like python manage.py runserver appears No module named 'django'. It seems that i am not pointing to my django project virtual env, but i dont know how to do that.
Execute command in my django app env path does not work neither.

Thanks a lot!
Before using of virtual env you should activate it. Execute env\activate or env\bin\activate. Not a windows guy so I'm not sure which path virtualenv uses on Windows :-)
You have to activate virtualenv. Go to env/Scripts directory and run activate.bat. Then go to your main project directory and try again python manage.py runserver. If you still see No module named 'django' make sure that django is installed in this environment try pip install django.
