Django项目导入包时报TypeError: unhashable type: 'Path'求助

编辑补充：已将问题范围缩小至Django REST Framework，但暂未明确根因，即将开始深度包调试。

搭建的小型Django项目中，只要在urls.py文件里执行任何from package import X导入操作，就会触发TypeError: unhashable type: 'Path'异常。如果该文件没有任何导入语句，项目能正常运行、服务器也能正常启动。

错误栈信息如下：

• 执行make up启动项目

这是首次尝试跨独立容器服务共享Django代码，此前从未遇到该问题。目前观察到coreapi相关环节出现错误，无论导入什么包，最终都会触发pkg_resources导入失败，暂未明确原因，恳请各位提供帮助。
