ubuntu更新python3版本并安装scapy

下载编译安装

下载wget https://www.python.org/ftp/python/3.7.3/Python-3.7.3.tgz其他版本下载&＃xff1a;https://www.python.org/downloads/source/解压
tar zxvf Python-3.7.3.tgz
cd Python-3.7.3编译
./configure --with-ssl
make
sudo make install报错解决
ZipError&＃xff1a;
sudo apt install zlib*
ImportError:&＃39;_ctypes&＃39;
sudo apt-get install python-dev python-setuptools python-pip python-smbus build-essential libncursesw5-dev libgdbm-dev libc6-dev zlib1g-dev libsqlite3-dev tk-dev libssl-dev openssl libffi-dev


注意&＃xff1a;–with-ssl必须加上&＃xff0c;否则使用pip安装第三方包时&＃xff0c;会引发ssl错误。导致无法使用。如果执行pip install出错&＃xff0c;重新编译安装即可。

查看python3.7位置

whereis python3.7

创建软连接

添加python3的软链接

sudo ln -s /usr/local/bin/python3.7 /usr/bin/python3.7

添加 pip3 的软链接

sudo ln -s /usr/local/bin/pip3.7 /usr/bin/pip3.7

你也可以先将原来的软连接删除&＃xff0c;再创建新的连接

sudo rm -rf /usr/bin/python3
sudo rm -rf /usr/bin/pip3


scapy安装

需要更新pip
python3 -m pip install --upgrade pip
python3 -m pip install --upgrade pip

安装scapy

pip3.7 install --pre scapy[complete]
或者 sudo pip3.7 install --pre scapy[complete]
记得给目录路径权限
sudo chmod 777 路径
