1.准备
安装依赖包
sudo apt-get install build-essential checkinstall
sudo apt-get install libreadline-gplv2-dev libncursesw5-dev libssl-dev libsqlite3-dev tk-dev libgdbm-dev libc6-dev libbz2-dev
# #
sudo apt-get install zlib1g-dev libbz2-dev libssl-dev libncurses5-dev libsqlite3-dev libreadline-dev tk-dev libgdbm-dev libdb-dev libpcap-dev xz-utils libexpat1-dev liblzma-dev libffi-dev libc6-dev
2.下载安装文件
# 下载到指定位置
cd /home/download
sudo wget https://www.python.org/ftp/python/3.7.0/Python-3.7.0.tgz
sudo tar xzf Python-3.7.0.tgz
3.安装路径
sudo mkdir -p /usr/local/python3
4.编译安装
执行这步是后面最好加上 --enable-optimizations 会自动安装pip3及优化配置
cd Python-3.7.0
sudo ./configure --prefix=/usr/local/python3 --enable-optimizations
sudo make
sudo make install
5.检查软链接
python3 -V
pip3 -V
# 若存在旧python3版本,备份旧版软链接
mv /usr/bin/python3 /usr/bin/python3.5
mv /usr/bin/pip3 /usr/bin/pip3.5
#添加python3的软链接
ln -s /usr/local/python3/bin/python3.7 /usr/bin/python3
#添加 pip3 的软链接
ln -s /usr/local/python3/bin/pip3.7 /usr/bin/pip3
