python - 如何在没有互联网访问的情况下在 Windows 10 上安装 virtualenvwrapper-win？

问题描述

我需要在 windows 10 上安装 virtualenvwrapper-win 。但是那台机器无法访问互联网。无论如何我可以下载并安装它而不是pip install virtualenvwrapper？

我已经尝试下载 virtualenvwrapper-4.8.4.tar.gz 和

pip install /PATH/TO/FILE/virtualenvwrapper-4.8.4.tar.gz

但我明白了

Complete output from command python setup.py egg_info:
Download error on https://pypi.python.org/simple/pbr/: [Errno 11001] getaddrinfo failed -- Some packages may not be found!
Couldn't find index page for 'pbr' (maybe misspelled?)

解决方案

在连接 Internet 的主机上运行

pip download virtualenvwrapper-win

pip下载包及其所有依赖项。将所有下载的文件移动到离线（未连接）主机并运行

pip install --no-index --find-links=\path\to\downloads virtualenvwrapper-win

替换\path\to\downloads为您将下载的安装文件移动到的目录的路径。

但我不认为pbr这是一种依赖。如果您仍然无法安装或运行 virtualenvwrapper-win 脚本，请pbr单独下载和安装。
