Django-无法“迁移”

Question

I am currently trying to deploy my new changes to my raspberry-pi (while virtualenv is activated), but with I run python manage.py migrate I receive the error below:

When I try to run sudo python manage.py migrate I receive:

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?

I have ran migrations before and it has been awhile since I have deployed, but nothing has changed and any troubleshooting help is appreciated.

Edit: Include that my virtualenv is activated

Answer 1

It's showing Django is not installed, you are possibly getting the error because you have not activated virtual environment. Go to the particular folder where virtual environment exists and try-

source myvenv/bin/activate

replace ' myvenv ' with your virtual environment name and try to migrate.
