• 从源码编译安装 python3.8

yum install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel libffi-devel gcc make
wget https://www.python.org/ftp/python/3.8.0/Python-3.8.0b3.tgz
tar -xvf Python-3.8.0b3.tgz
cd Python-3.8.0b3
./configure --prefix=/app/python/python3.8
make & make install
ln -s /app/python/python3.8/bin/python3.8 /usr/bin/python3.8
ln -s /app/python/python3.8/bin/pip3.8 /usr/bin/pip3.8

• 安装 mycli

pip3.8 install mycli

• 安装完后, 直接运行, 报错:
