我正在学习Django Rest Framework。 我使用format_suffix_patterns支持Urls中的后缀 一切都很好，直到突然我开始出现错误
_frozen_importlib._DeadlockError：_ModuleLock（'django.test.signals'）在1367726740816处检测到死锁
和
OSError：[WinError 123]文件名，目录名称或卷标语法不正确：''
即使使用
导入“ format_suffix_patterns”from rest_framework.urlpatterns import format_suffix_patterns
给出错误。
但是在我开始使用视图集之前，没有问题。
我尝试删除了旧的环境并创建了一个新的环境 删除pycache并重试
这是造成错误的包含项
from rest_framework.urlpatterns import format_suffix_patterns
完整错误

答案 0 :(得分：0)
即使我遇到同样的错误。
我评论了以下代码，它对我有用。
from rest_framework.urlpatterns import format_suffix_patterns
urlpatterns = format_suffix_patterns(urlpatterns)
