zc.buildout构建项目时报错‘AttributeError: '_NamespacePath' object has no attribute 'sort'’

在使用zc.buildout构建项目时如果碰到‘AttributeError: ‘_NamespacePath‘ object has no attribute ‘sort‘’报错：

An internal error occurred due to a bug in either zc.buildout or in a
recipe being used:

AttributeError: ‘_NamespacePath‘ object has no attribute ‘sort‘

可以尝试升级一下setuptools来解决这个问题：

pip3 install --upgrade setuptools
