"Error: No such command"

Dear Regis,
I’m trying AWS Official Tutor AMI, but I got “Error: No such command” when fixing django.db.utils.OperationalError: (1050, “Table ‘student_anonymoususerid’ already exists”)
using https://docs.tutor.overhang.io/troubleshooting.html#running-migrations-killed-command-failed-with-status-137-docker-compose or https://github.com/overhangio/tutor/issues/310
Please help
Best V

Hi @vitaly13! What command are you running? What is the full error stacktrace?
