目前面臨的問題，在kali操作系統中默認安裝了python2和python3，但是pip命令所安裝的庫都在python2里面，無法引入python3
這就導致使用python3 代碼引用第三方庫存在問題，故通過源碼安裝python3.7來解決問題。
首先下載python3.7
wget https://www.python.org/ftp/python/3.7.0/Python-3.7.0.tgz解壓並新建安裝python環境的目錄
tar -zxvf Python-3.7.0.tgz
編譯之前，安裝一些所要依賴的包
apt-get install -y make build-essential libssl-dev zlib1g-dev libbz2-dev libreadline-dev libsqlite3-dev wget curl llvm libncurses5-dev libncursesw5-dev xz-utils tk-dev
假如報錯了，就刪除對應的lock
rm /var/cache/apt/archives/lock編譯安裝
./configure --enable-optimizations --prefix=/usr/local/Python-3.7/ && make && make install
建立軟連接
ln -s -b /usr/local/python3.7/bin/python3.7 /usr/bin/python
ln -s -b /usr/local/python3.7/bin/pip3 /usr/bin/pip3
