1. 下载指定版本下文中以3.7.3为例

wget https://www.python.org/ftp/python/3.7.3/Python-3.7.3.tgz

1. 解压

tar zxvf Python-3.7.3.tgz

1. 切换目录

cd Python-3.7.3

1. 编译

./configure --with-ssl
make
sudo make install
–with-ssl必须加上，否则使用pip安装第三方包时，会引发ssl错误。导致无法使用

1. 安装python依赖

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

1. 添加软连接 (方便区分不同版本)

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
