python - 如何使用 pip3 安装如果我已经有包裹，则离线

Question

我可以安装一个本地包，如下所示：

....,root,root # /usr/bin/pip3 install PyYAML-5.3.tar.gz
WARNING: Running pip install with root privileges is generally not a good idea. Try `pip3 install --user` instead.
Processing ./PyYAML-5.3.tar.gz
Installing collected packages: PyYAML
  Found existing installation: PyYAML 3.13
    Uninstalling PyYAML-3.13:
      Successfully uninstalled PyYAML-3.13
  Running setup.py install for PyYAML ... done
Successfully installed PyYAML-5.3
....,root,root #

但是如果我尝试下面的命令它会失败，因为它会在互联网上搜索（我的虚拟机没有互联网连接）

,root,root # /usr/bin/pip3 install PyYAML==5.3
WARNING: Running pip install with root privileges is generally not a good idea. Try `pip3 install --user` instead.

所以问题是将我下载的包“PyYAML-5.3.tar.gz”放在默认位置以使此命令（/usr/bin/pip3 install PyYAML==5.3）在本地而不是在互联网上查找它？
