linux环境中没有网络怎么下载python

1.下载指定的包到指定文件夹。
 pip list #查看安装的包
  pip freeze > requirements.txt  将已经通过pip安装的包的名称记录到 requirements.txt文件中
 创建存放安装包的目录：mkdir /packs
      pip install  --download  /packs pandas(存放一个pandas包)
             或
　　     pip install  --download  /packs -r requirements.txt（存放requirements.txt列出的所有包）
2.安装指定的离线包
  pip install  --no-index  --find-links=/packs/  pandas 或
  pip install  --no-index  --find-links=/packs/  -r  requirements.txt  （也可能是 --find-link)
