w3af安装(处理python2和3，pip2和3混乱的问题)

git clone --depth 1 https://github.com/andresriancho/w3af.git

在这里插入图片描述
打开w3af_gui看一下

要求必须是python2
但我的/usr/bin/env中的python是python3

我们将/usr/bin/env中的python换成python2

which python2
#/usr/bin/python2

rm /usr/bin/python

sudo ln -s /usr/bin/python2 /usr/bin/python

现在terminal输入python，看到的是python2了

需要安装pip2

pip -V看一波
在这里插入图片描述
pip 和 pip3 指向的实际都是python3

curl -o get-pip.py https://bootstrap.pypa.io/pip/2.7/get-pip.py
sudo python2 get-pip.py

在这里插入图片描述
现在pip2指向python2了

终于进入其他教程讲解的第一步了

apt-get update一下试试

再执行

确实在下载依赖了

还是不行

核心问题应该还是这个
