Django Migration File with Invalid import (import no longer exists)

[Ray Leyendecker]

I recently update the oauth2 library I am using in my project.

There are now import references in my (already run) migration files that no longer exist (as a result of the oauth2 upgrade).

As a result the make migrations command fails.

How is the best way to handle this problem?

I am also running my project on AWS (Amazon Web Services) so a solution that can be applied to that environment we be much appreciated.

Thanks

Hi Ray,

Follow the advice at https://docs.djangoproject.com/en/stable/topics/migrations/#historical-models :

"To remove old references, you can squash migrations or, if there aren’t many references, copy them into the migration files."
