python3 manage.py migration出现错误

Question

I just started a new project and change database engine

DATABASES = {
'default': {
    'ENGINE': 'mysql.connector.django',
    'NAME': 'mysite',
    'USER': 'root',
    'PASSWORD': 'mypassword',
    'HOST': '127.0.0.1',
    'PORT': '3306',
}

} then after running python3 manage.py migrate i got an error:

Operations to perform:
  Apply all migrations: admin, auth, contenttypes, sessions
Running migrations:
  Applying contenttypes.0001_initial...Traceback (most recent call last):

Answer 1

You have to:

python3 manage.py makemigrations 

And then:

python3 manage.py migrate

Then you can safely start the server again

Hope this helps
