離線安裝python的requests庫方法
前言
本文詳細記錄瞭在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)、無法連接互聯網
1、下載安裝包
1.1 檢查requests模塊所需依賴包
在可以上網且已經安裝python的機器上檢查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 上找到相應的程序,下載並傳輸至目標機器。
1.3 下載requests包
從github下載requests源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,前面三個有報錯信息,目前暫時忽略,因為經過驗證沒有影響requests安裝。
D:\python-lib>pip install urllib3-1.26.8-py2.py3-none-any.whl Processing d:\python-lib\urllib3-1.26.8-py2.py3-none-any.whl Installing collected packages: urllib3 ERROR: After October 2020 you may experience errors when installing or updating packages.

2.2 安裝requests
在解壓好的equests-master目錄下打開cmd(或者cmd中切換目錄至該路徑)
輸入命令開始安裝
python setup.py install
3、檢查是否安裝成功
在python中使用import requests查看
