um -y install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel

yum install libffi-devel -y

下载Python3

wget https://www.python.org/ftp/python/3.7.0/Python-3.7.0.tgz

解压编译安装

1. tar -zxvf Python-3.7.0.tgz

2. cd Python-3.7.0

3. ./configure --prefix=/usr/local/python3

4. make && make install

建立python3的软链

ln -s /usr/local/python3/bin/python3 /usr/bin/python3

将/usr/local/python3/bin加入PATH

PATH=$PATH:$HOME/bin:/usr/local/python3/bin

 

linux python3换pip 源
