话不多说，在Linux上完成Python从源码编译安装全流程

话不多说，直接上代码：

# 安装工具链，如果已装完请跳过
sudo apt-get install -y gcc g++ make cmake zlib1g zlib1g-dev libbz2-dev libsqlite3-dev libssl-dev libxslt1-dev libffi-dev unzip pciutils net-tools libncursesw5-dev# 把需要安装的版本号在这里改，后面会联动改动，当然前提是ftp上有
VERSION=3.8.9# 清除上次下载和安装的目录
sudo rm Python-$VERSION.tgz
sudo rm -rf Python-$VERSION
sudo rm -rf /usr/local/python$VERSION# 下载解压配置编译安装一套连招
wget https://www.python.org/ftp/python/$VERSION/Python-$VERSION.tgz
tar -zxvf Python-$VERSION.tgz
cd Python-$VERSION
./configure --prefix=/usr/local/python$VERSION --enable-loadable-sqlite-extensions --enable-shared
make -j 4
sudo make install -j 4# 添加到环境变量，并且注释也加上了
echo "" >> ~/.bashrc
echo "# Add python$VERSION to PATH" >> ~/.bashrc
echo "export LD_LIBRARY_PATH=/usr/local/python$VERSION/lib:\$LD_LIBRARY_PATH" >> ~/.bashrc
echo "export PATH=/usr/local/python$VERSION/bin:\$PATH" >> ~/.bashrc# 这一行需要手动运行，或者重启终端也行
source ~/.bashrc
