crontab で 1 日 1 回実行するスクリプトがあります。それは私のデスクトップでうまくいきます。しかし、RPi の virtualenv で実行しようとすると、次のエラーが発生します。
Traceback (most recent call last):

django.core.exceptions.ImproperlyConfigured: Requested setting CACHES, but settings are not configured. You must either define the environment variable DJANGO_SETTINGS_MODULE or call settings.configure() before accessing settings.
使えないようです:
from django.contrib.auth.models import User
何が問題ですか?
