離線安裝python的requests庫方法

前言

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

環境：win7、python3.8.9（win7中可安裝的最新python版本）、無法連線網際網路

1、下載安裝包

1.1 檢查requests模組所需依賴包

在可以上網且已經安裝python的機器上檢查requests模組需要哪些依賴包，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

發現需要chardet，idna，urllib3，certifi

檢查這幾個包是否已安裝，如果未安裝，則也需要手工安裝。

1.2 下載requests所需依賴包

在網站 https://www.lfd.uci.edu/~gohlke/pythonlibs 上找到相應的程式，下載並傳輸至目標機器。

1.3 下載requests包

從github下載requests原始碼包並傳輸至目標機器。

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

下圖中最後一個是正常安裝成功，前面三個有報錯資訊，目前暫時忽略，因為經過驗證沒有影響requests安裝。
