Postgresql – Unable to use psycopg2 with Postgres in Django

As stated in my question, I am now configuring my djagno project to connect with postgres. The issue i am facing is that, when making migrations, it shows me the following error:

python manage.py makemigrations
Traceback (most recent call last):
File "E:CodeEcomEcomecomLibsite-packagesdjangodbbackendspostgresqlbase.py", line 25, in <module>
  import psycopg as Database
ModuleNotFoundError: No module named 'psycopg'

During handling of the above exception, another exception occurred:

  )

i have tried literally everything, from adding psql to path to trying to install previous version of psycopg2, but to no avail. I have also ran a dozen session on chatgpt

Can someone help me with this?

    This was actually really simple. I was using python 3.13 previously. I downgraded to 3.12, created a new virtualenv, and the migrations ran smoothly.

    To resolve this PostgreSQL connection issue in Django you can follow this-

    First, install the correct PostgreSQL database driver. Use:

    pip install psycopg2-binary

    If you prefer the regular psycopg2, you’ll need the PostgreSQL binaries installed first:

    pip install psycopg2

    Make sure your settings.py has the correct database configuration:

    DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.postgresql',
        'NAME': 'put_your_db_name',
        'USER': 'put_your_username',
        'PASSWORD': 'put_your_password', # or use from env
        'HOST': 'localhost',
        'PORT': '5432',
    }
}
