我正在使用pip3 list --outdated --format=freeze进行当前安装的所有软件包的批量更新。
最近，我注意到一个包rst2pdf是要保留在pip3 install -U之后的。
我在MacOS High Sierra和Ubuntu 16.04上遇到此问题。
从python编程的角度来看，没关系，因为我可以使用它。
但是从系统管理员的角度来看，所有时间包都在下载，并且浪费时间和带宽。
有什么方法可以从pip3 list --outdated输出中删除成品？
这是命令输出：
bash-3.2$ pip3 install -U rst2pdf

最佳答案
https://pypi.python.org/pypi/rst2pdf上没有可下载的软件包-无需更新。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
