Python 与 Django 导入错误与 RegistrationSupplementBase 无法导入名称“ugettext_lazy”

Question

I'm updating a very old Django project and trying to use RegistrationSupplementBase but when importing I get this error message:

File "/home/projectmachine/Desktop/project_rebuild/projectname/models.py", line 11, in <module>
from registration.supplements.base import RegistrationSupplementBase
File "/home/projectmachine/.local/share/virtualenvs/projectname-QrYA9Qp-/lib/python3.6/site-packages/registration/supplements/base.py", line 9, in <module>
    from django.utils.text import ugettext_lazy as _
ImportError: cannot import name 'ugettext_lazy'

I can't figure out what's wrong. It seems like there is an issue with the dependancies installed. I'm using Django 2.2 with django-inspectional-registration 0.6.2

Here is how I am importing the class:

from registration.supplements.base import RegistrationSupplementBase

The function has been moved to the django.utils.translation module, so you can import this with:

from  import ugettext_lazy as _

Based on the Django Deprecation Timeline [Django-doc] , ugettext_lazy will be removed in django-4.0 . You can use gettext_lazy instead:

from django.utils.translation import  as _

Based on theGitHub repository of django-inspectional-registration however, the project is not active anymore: the latest commit was in november 2016. You can try to update the project, but perhaps it is better to look for an alternative package that works in a similar way.
