pkg_resources.DistributionNotFound: 未找到 'Sphinx==1.8.5' 分布，应用程序需要该分布
pkg_resources.DistributionNotFound: The 'Sphinx==1.8.5' distribution was not found and is required by the application
当我尝试 sphinx-build --version 时，弹出此错误消息：
File "/usr/lib/python3/dist-packages/pkg_resources/__init__.py", line 786, in resolve
raise DistributionNotFound(req, requirers)
pkg_resources.DistributionNotFound: The 'Sphinx==1.8.5' distribution was not found and is required by the application
如何修复？
U 从 system-package-managemetn（例如，apt）和 pip 安装 sphinx。只需删除系统方面的狮身人面像。
