升级Django到4.x后rest_auth引发ImportError问题求助

我最近正在把项目从Django 3.2升级到4.0版本，结果遇到了一个导入错误，折腾半天没搞明白，来求助大家！

升级后弹出的错误提示如下：

ImportError: cannot import name 'ugettext_lazy' from 'django.utils.translation'

查了错误来源，发现是rest_auth/registration/serializers.py里的这行导入语句引发的问题：

from django.utils.translation import ugettext_lazy as _

说下我的环境：目前用的是Django 4.0.10，搭配djangorestframework 3.13.0。之前看DRF的发布说明，v3.13.0应该是支持Django 4.0的，后来我又换成了v3.14.0试了试，结果还是报同样的错，实在搞不懂哪里遗漏了。

附上完整的错误追踪栈：
