大家好，本篇文章主要講的是離線安裝python的requests庫方法，感興趣的同學(xué)趕快來看一看吧，對(duì)你有幫助的話記得收藏一下

前言

本文詳細(xì)記錄了在win7中離線安裝python requests的過程，包括安裝requests所需依賴包。

環(huán)境：win7、python3.8.9（win7中可安裝的最新python版本）、無法連接互聯(lián)網(wǎng)

1、下載安裝包

1.1 檢查requests模塊所需依賴包

在可以上網(wǎng)且已經(jīng)安裝python的機(jī)器上檢查requests模塊需要哪些依賴包，如果這些依賴包未安裝，直接安裝requests也不能使用。

使用命令：

pip show requests

發(fā)現(xiàn)需要chardet，idna，urllib3，certifi

檢查這幾個(gè)包是否已安裝，如果未安裝，則也需要手工安裝。

1.2 下載requests所需依賴包

在網(wǎng)站 https://www.lfd.uci.edu/~gohlke/pythonlibs 上找到相應(yīng)的程序，下載并傳輸至目標(biāo)機(jī)器。

1.3 下載requests包

從github下載requests源碼包并傳輸至目標(biāo)機(jī)器。

https://github.com/kennethreitz/requests

將requests-master.zip解壓到python的安裝目錄中

2、安裝

2.1 安裝requests所需依賴包

安裝命令為

 pip install xx.whl

下圖中最后一個(gè)是正常安裝成功，前面三個(gè)有報(bào)錯(cuò)信息，目前暫時(shí)忽略，因?yàn)榻?jīng)過驗(yàn)證沒有影響requests安裝。
