tar -xvf Python-3.7.3.tar
3.yum -y install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel libffi-devel
4.cd python-3.7.3
./configure --prefix=/usr/local/python37 --enable-optimizations
5.make && make install
6.注册PATH环境变量
