Ich kann die Python Website nicht lokal starten.

[Benno12]

Ich habe auf GitHub ein Repository runtergeladen, und versuche es zu starten es funktioniert leider nicht.
Meine Schritte:
Ich habe mir das als ZIP runtergeladen: https://github.com/Ronik22/Django_Social_Network_App
Ich habe es im CMD ausgewählt und habe eine virtuelle env geschaffen: virtualenv myenv
Danach: myenv\Scripts\activate
Danach als (myenv) aktiv war: pip install -r requirements.txt
Das hat geklappt, bzw. es sind keine ERRORS aufgeplopt.
Danach noch: python manage.py makemigrations
python manage.py migrate

Dann habe ich versucht es zu starten: python manage.py runserver

Dann kam der Text:

Sagt die Fehlermeldung doch sehr klar. SECRET_KEY darf nicht leer sein. Ist sie aber. Musst du setzten. Ist auch lang und breit dokumentiert. https://docs.djangoproject.com/en/3.2/ref/settings/

Tut mir leid das ich nachfrage, aber wo muss ich setzen?
# SECURITY WARNING: keep the secret key used in production secret!
SECRET_KEY = os.getenv("muss ich hier etwas anderes setzen?")

oder hier:

GOOGLE_RECAPTCHA_SECRET_KEY = os.getenv("hier?")

@Benno12: Die Werte werden offenbar als Umgebungsvariablen erwartet. Als solche muss man sie vor dem Start des Programms setzen. Wie das geht ist vom Betriebssystem abhängig.
