Startup with Django runserver error
I am starting up with Python-Django in Ubuntu 18.04. I have python3 installed. python3 —version says Python 3.5.2 After installing Python, I installed Django as below:
sudo apt install python3-pip pip3 install django I also have Django installed. django-admin —version says 2.0.5 In my project, startproject worked successfully, but when I am trying to run the following command inside my project:
python3 manage.py runserver Traceback (most recent call last): File "manage.py", line 8, in from django.core.management import execute_from_command_line ImportError: No module named 'django' The above exception was the direct cause of the following exception: Traceback (most recent call last): File "manage.py", line 14, in ) from exc 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? python3 -c "import django; print(django.__path__)" python3 -c "import django; print(django.__path__)" Traceback (most recent call last): File "", line 1, in ImportError: No module named 'django' which django gives blank output echo $PYTHONPATH gives blank output python3 -m django —version says /usr/local/bin/python3: No module named django echo $PATH shows /home/shobhit/.local/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin What is the problem and what is the solution here? Update ls /usr/local/lib | grep python says
Django — Cannot run «py manage.py runserver»
When I run py —version, it works fine. I want to know why it says python was not found, when it works just fine. I haven’t found anything online.

You are checking for py —version and on the other hand executing the command python manage.py runserver .
And check if you have two versions of python installed on your machine.
I might be wrong here with my answer, but when I run the two different commands to check the version installed, I get two different versions.
If python is properly installed (available to be accessed from terminal) you should be able to simply type «python» and enter a python shell. To verify, try:
This should output 4. If typing python does not take you to the python shell, I’m guessing you need to add python as a PATH variable.
I can’t. It sends me to the Microsoft store. However, I am able to enter the Python interpreter by typing py. Thanks for helping btw.
Uninstall Python, redownload from Anaconda distributer. Make sure to Add Python to PATH when configuring settings in the installation setup. Please accept my answer if your problem was solved. Thanks.
If you are using older versions of Django, say Django 3.1 and below then
python manage.py runserver should work ok.
I advise you to stick to python and not py .
But in the newer versions of Django, say Django 3.2 and above then it is much simpler to run your server
simply use: manage.py runserver or python manage.py runserver

Начал изучать django, создал проект, попытался запустить сервер с помощью команды python manage.py runserver, но выдает ошибку. Подскажите, пожалуйста, в чем проблема. Ошибка:
