离线安装python的requests库方法
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
