python - "pip3 list --outdated"项目在 "pip3 install -U"之后保留剩余

Question

我正在使用 pip3 list --outdated --format=freeze 批量更新当前安装的所有软件包。 最近我注意到一个包 rst2pdf 在 pip3 install -U 之后保留下来。
我在使用 MacOS High Sierra 和 Ubuntu 16.04 时遇到了这个问题。

从python编程的角度来看，这并不重要，因为我可以使用它。 但从系统管理员的角度来看，所有的包都在下载，浪费时间和带宽。

有什么方法可以从 pip3 list --outdated 输出中删除已完成的项目吗？

这是命令输出:

bash-3.2$ pip3 install -U rst2pdf
