我們經常看到一些網站上很精彩的視頻，想下載下來長期保存，但網站一般都設了限制，越來越難下載。下面我講一下在KALI系統之下利用PYTHON庫——you-get下載網頁視頻的方法。
一、接上一篇文章，先安裝好PYTHON，然後打開終端，輸入代碼：sudo pip3 install you-get，回車，但安裝失敗，出現錯誤代碼；
┌──(hero㉿kali)-[~/桌面]
└─$ sudo pip3 install you-get
[sudo] hero 的密碼：
WARNING: Retrying (Retry(total=4, connect=None, read=None, redirect=None, status=None)) after connection broken by 'ReadTimeoutError("HTTPSConnectionPool(host='pypi.org', port=443): Read timed out. (read timeout=15)")': /simple/you-get/
WARNING: Retrying (Retry(total=3, connect=None, read=None, redirect=None, status=None)) after connection broken by 'ReadTimeoutError("HTTPSConnectionPool(host='pypi.org', port=443): Read timed out. (read timeout=15)")': /simple/you-get/
WARNING: Retrying (Retry(total=2, connect=None, read=None, redirect=None, status=None)) after connection broken by 'ConnectTimeoutError(<urllib3.connection.HTTPSConnection object at 0x7f7fe35a5df0>, 'Connection to pypi.org timed out. (connect timeout=15)')': /simple/you-get/二、解決以上安裝錯誤的思路為換安裝源，輸入代碼：sudo pip3 install you-get -i http://mirrors.aliyun.com/pypi/simple/ –trusted-host mirrors.aliyun.com，回車，輸入密碼，安裝成功；
┌──(hero㉿kali)-[~/桌面]
└─$ sudo pip3 install you-get -i http://mirrors.aliyun.com/pypi/simple/ --trusted-host mirrors.aliyun.com
[sudo] hero 的密碼：
