Le démarrage du serveur Web Airflow échoue avec sqlalchemy.exc.NoInspectionAvailable: Aucun système d'inspection n'est disponible

Installation correctement effectuée. db lancé correctement et en essayant de démarrer le serveur Web affiche l'erreur suivante.

J'ai tout réinstallé mais cela ne fonctionne toujours pas.

J'apprécierai si quelqu'un m'aide.

Sortie de la console:

$:~/airflow# airflow webserver -p 8080

J'ai fait face au problème ci-dessus. J'ai ajouté la ligne ci-dessous dans Dockerfile

&& pip install SQLAlchemy==1.3.15 \

Construisez l'image docker comme

docker build --rm -t <tag> .

Courir :

docker run -d -p 8080:8080 <tag>
