我在CentOs7上安装了一个独立的python版本，并基于它激活了虚拟环境。当我从离线包中使用pip install方法时，我得到了这个错误：
ERROR: Command errored out with exit status 127:

我从包含使用命令pip download下载的所需软件包的文件夹进行安装，然后使用pip install -r requirements.txt --no--index --find-links=pkgs脱机安装它们
下面的链接，该人员建议使用在虚拟环境中安装python包时的easy_install
示例
使用此命令有助于path/to/python/python3.6 -m pip install -r requirements.txt --no-index --find-links=path/to/pkgs
