“pip3列表过期”项将保留在“pip3 install U”之后

Question

我正在使用pip3 list --outdated --format=freeze对当前安装的所有包进行批量更新。 最近我注意到一个包rst2pdf是在pip3 install -U之后继续保留。
我在MacOS High Sierra和Ubuntu16.04中遇到了这个问题。在

从python编程的角度来看，这无关紧要，因为我可以使用它。 但从系统管理的角度来看，所有的时间包都在下载，这是在浪费时间和带宽。在

有没有办法从pip3 list --outdated输出中删除完成的项？在

以下是命令输出：

bash-3.2$ pip3 install -U rst2pdf

在https://pypi.python.org/pypi/rst2pdf没有可下载的包-没有可从中更新的包。您可以尝试从https://github.com/rst2pdf/rst2pdf升级

pip install  upgrade git+https://github.com/rst2pdf/rst2pdf.git#egg=rst2pdf
