Django：使用sudo在虚拟环境中运行服务器

Question

I got Django set up on my server.

I have activated my virtual environment and I'm able to run server successfully on port 8000:

python manage.py runserver

I would like to use port 80 so I'm able to access (test) my app from outside so I use:

sudo python manage.py runserver

But this gives me an error:

Traceback (most recent call last):

      File "manage.py", line 17, in <module>
        "Couldn't import Django. Are you sure it's installed and "
    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?

Can someone please explain why?

Answer 1

The problem occurs if you create the virtualenv without the sudo command,

virtualenv is a separate environment available to the user created,

so if you run python manage.py runserver without the sudo command it will run properly,

or else install django will sudo right and try sudo python manage.py runserver

Answer 2

You can try:

sudo `which python` manage.py runserver

inside your virtualenv to run django from sudo. Hope it helps.
