添加PYTHONPATH环境变量后仍无法导入Django，求技术支持

Let’s work through this issue step by step—here are the key checks and fixes to resolve the "Couldn't import Django" error:

1. Use your virtual environment’s Python executable directly #

Even though your terminal shows (py1) activated, environment variable conflicts might be pulling in the system Python instead. Bypass this by running the command with the full path to your virtual environment’s Python:

C:\Users\NIKITA~1\Envs\py1\Scripts\python.exe manage.py runserver

2. Confirm Django is installed in your py1 environment #

It’s possible Django wasn’t installed in the virtual environment you’re using. Run this in your activated py1 terminal to check:

pip show django

If Django isn’t listed, install it immediately with:

pip install django

3. Check if your manual PYTHONPATH is causing conflicts #

Virtual environments handle their own PYTHONPATH automatically—adding a custom one can override the environment’s default paths, blocking access to Django.

To test this:

• Temporarily remove the PYTHONPATH you added from your system environment variables.
• Close and re-open your terminal, re-activate py1, then run python manage.py runserver again.

You can also verify which paths Python is using with this command—look for C:\Users\NIKITA~1\Envs\py1\lib\site-packages (where Django should live) in the output:

python -c "import sys; print('\n'.join(sys.path))"

4. Inspect your manage.py file #

Open manage.py and ensure it doesn’t have a hard-coded path to a different Python interpreter. The top of the file should look like this (no custom paths):

#!/usr/bin/env python
import os
import sys

def main():
    os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'raksh.settings')
    try:
        from django.core.management import execute_from_command_line
    except ImportError as exc:
        raise 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?"
        ) from exc
    execute_from_command_line(sys.argv)

if __name__ == '__main__':
    main()
