带有 RegistrationSupplementBase 的 Django 导入错误的 Python 无法导入名称 'ugettext_lazy'

Question

我正在更新一个非常旧的 Django 项目并尝试使用 RegistrationSupplementBase 但在导入时我收到此错误消息:

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'

我不知道哪里出了问题。安装的依赖项似乎存在问题。我正在使用 Django 2.2 和 django-inspectional-registration 0.6.2

这是我导入类的方式:

从 registration.supplements.base 导入 RegistrationSupplementBase

Answer 1

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

该函数已移至 django.utils.translation 模块，因此您可以将其导入:

from <b>django.utils.translation</b> import ugettext_lazy as _

基于Django Deprecation Timeline [Django-doc] , ugettext_lazy 将在 django-4.0 中删除.您可以改用 gettext_lazy:

from django.utils.translation import <b>gettext_lazy</b> as _

基于GitHub repository of django-inspectional-registration然而，该项目不再活跃:最新的提交是在 2016 年 11 月。您可以尝试更新该项目，但也许最好寻找一个以类似方式工作的替代包。
