Python Django错误导入ProhibitNullCharactersValidator

当我运行django应用程序时引发此错误，这是一个与版本相关的错误，我使用的是python 3.6和django 1.11.10：

from rest_framework_swagger.views import get_swagger_view
      File "/home/eddy/Documentos/apps/django/multas/venv/lib/python3.6/site-packages/rest_framework_swagger/views.py", line 3, in <module>
        from rest_framework.renderers import CoreJSONRenderer
      File "/home/eddy/Documentos/apps/django/multas/venv/lib/python3.6/site-packages/rest_framework/renderers.py", line 22, in <module>
        from rest_framework import VERSION, exceptions, serializers, status
      File "/home/eddy/Documentos/apps/django/multas/venv/lib/python3.6/site-packages/rest_framework/serializers.py", line 29, in <module>
        from rest_framework.fields import get_error_detail, set_value
      File "/home/eddy/Documentos/apps/django/multas/venv/lib/python3.6/site-packages/rest_framework/fields.py", line 15, in <module>
        from django.core.validators import (
    ImportError: cannot import name 'ProhibitNullCharactersValidator'
    Unhandled exception in thread started by <_pydev_bundle.pydev_monkey._NewThreadStartupWithTrace object at 0x7f7046347f98>

在此代码中，引发错误：

from django.core.validators import (
    EmailValidator, MaxLengthValidator, MaxValueValidator, MinLengthValidator,
    MinValueValidator, ProhibitNullCharactersValidator, RegexValidator,
    URLValidator, ip_address_validators
)

---

ProhibitNullCharactersValidator

是Django 2.0中新增的

看

此外，Django REST框架

3.12.0

及更高版本不再支持

Django 1.11

。请参阅djangorestframework 3.12.0的部分

必须升级

Django

或降级Django REST框架至3.11.2

from django.core.validators import (
    EmailValidator, MaxLengthValidator, MaxValueValidator, MinLengthValidator,
    MinValueValidator, ProhibitNullCharactersValidator, RegexValidator,
    URLValidator, ip_address_validators
)
