How can a django project determine if a django system is installed?

I built a small project in my system.
After creating the project, I put it on a USB drive and copied it to another system.
When I run a project, how can it determine if django is installed on the system or if the system has all the requirements for the project?

For example, I made a sample blog project on a laptop, and then copied this project (blog) to a USB drive, and then copied this project (blog) to my own system. After copying, I tried to start the project. If django is installed, then the project runs successfully. But when django is not installed, it gives an error in the terminal.

How can a program determine if the required one is installed (Django / Python)?

Just the module will not be found when you try to start the project.

You can run "python" on the command line and try to "import django" if it returns an error and django is not found, which means that django is not installed on the current machine.

When you try to start a Django project, you will get an ImportError, and I think this is the detection django installed or not.

ImportError: No module named django

You can write a new management command to your project to check if django is installed on the system or not. and you can work like.

python manage.py is_django_installed

even you can configure the runter / migrate / syncdb server management command to verify that django is installed or not.
