[Django]-Python Django: You're using the staticfiles app without having set the STATIC_ROOT setting

If you are using Django 2.2 or greater, your settings file already has a line similar to this:

# Build paths inside the project like this: os.path.join(BASE_DIR, ...)
BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))

Therefore you can easily set static like so:

STATIC_URL = '/static/'
STATIC_ROOT = os.path.join(BASE_DIR, 'static')

Set the STATIC_ROOT setting to the directory from which you’d like to serve static files, for example:

STATIC_ROOT = "/var/www/example.com/static/"

The settings you are using are for development. Check the Django docs for more information here

Django settings for static assets can be a bit difficult to configure and debug. However, if you just add the following settings to your settings.py, everything should work exactly as expected:

goto "settings.py" add following code

BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))
# Static files (CSS, JavaScript, Images)
# https://docs.djangoproject.com/en/1.9/howto/static-files/
STATIC_ROOT = os.path.join(BASE_DIR, 'staticfiles')
STATIC_URL = '/static/'

# Extra places for collectstatic to find static files.
STATICFILES_DIRS = (
    os.path.join(BASE_DIR, 'static'),
)

See a full version of our example settings.py on GitHub.

now create static folder in root directory, and a random file inside
it.

Django won’t automatically create the target directory (STATIC_ROOT) that collectstatic uses, if it isn’t available. You may need to create this directory in your codebase, so it will be available when collectstatic is run. Git does not support empty file directories, so you will have to create a file inside that directory as well.

This is the most basic and easy solution, i faced the same error while installing datta admin.
This solved my problem. Add this code in your settings.py file in your project core directory.

STATIC_URL = 'static/'
STATIC_ROOT = BASE_DIR / STATIC_URL
