前言

 本文详细记录了在win7中离线安装python requests的过程，包括安装requests所需依赖包。

环境：win7、python3.8.9（win7中可安装的最新python版本）、无法连接互联网

1、下载安装包

1.1 检查requests模块所需依赖包

在可以上网且已经安装python的机器上检查requests模块需要哪些依赖包，如果这些依赖包未安装，直接安装requests也不能使用。

使用命令：

pip show requests

 发现需要chardet，idna，urllib3，certifi

检查这几个包是否已安装，如果未安装，则也需要手工安装。

1.2 下载requests所需依赖包

在网站 https://www.lfd.uci.edu/~gohlke/pythonlibs 上找到相应的程序，下载并传输至目标机器。

1.3 下载requests包

从github下载requests源码包并传输至目标机器。

https://github.com/kennethreitz/requests

将requests-master.zip解压到python的安装目录中

2、安装

2.1 安装requests所需依赖包

安装命令为

 pip install xx.whl

下图中最后一个是正常安装成功，前面三个有报错信息，目前暂时忽略，因为经过验证没有影响requests安装。

2.2 安装requests

在解压好的equests-master目录下打开cmd（或者cmd中切换目录至该路径）

 输入命令开始安装

python setup.py install

3、检查是否安装成功

在python中使用import requests查看
