Django development: ERRORS:? : (staticfiles.E001) The STATICFILES_DIRS setting is not a tuple or list.

Once again, as a reminder, I encountered a subtle problem while developing with Django. It’s a simple problem, but it’s easy to ignore.

The specific error information is as follows:

ERRORS: ? : (staticfiles.E001) The STATICFILES_DIRS setting is not a tuple or list. HINT: Perhaps you forgot a trailing comma?

System check identified 1 issue (0 silenced).

The error is that our STATICFILES_DIRS was assigned to an array object in the wrong form:

Go to settings.py,

the

STATICFILES_DIRS=(os.path.join(BASE_DIR,’static’))

Instead of

STATICFILES_DIRS=[(os.path.join(BASE_DIR,’static’))]
