Python2.7 install pip

问题背景：steghide 本身并不支持爆破，需要一些其他的方法 https://github.com/Va5c0/Steghide-Brute-Force-Tool ，这个脚本需要安装库 progressbar（使用的是 python2）

默认 pip 指向的是 python3

┌──(kali㉿kali)-[/usr/lib/python2.7/dist-packages/pip-23.1.2]
└─$ pip -V
pip 23.2.1 from /home/kali/.local/lib/python3.11/site-packages/pip (python 3.11)

如何为 python2.7 安装 pip 成了一个问题，尝试搜索得到的答案是 python2.7 已经不在维护，kali 中也删去了 python2.7 的 pip

解决方案：

New Kali build cannot install pip for python2.7

┌──(kali㉿kali)-[~]
└─$ curl https://bootstrap.pypa.io/pip/2.7/get-pip.py  -o py2-get-pip.py

└─$ python2 py2-get-pip.py
