CentOS 7 安装最新版的Python和pip

前往 下载最新版的python

下载好后解压编译安装：

yum install zlib zlib-devel openssl openssl-devel

tar -zxvf Python-XXXXXX.tgz

cd Python-XXXXXX.tgz

./configure

make && make install

ln -sf /usr/local/bin/python3 /usr/bin/python

mv /usr/bin/pip /usr/bin/pip.bak

ln -s /usr/local/bin/pip3 /usr/bin/pip

升级后yum运行会报错，需要修改两个地方：

vi /usr/bin/yum

vi /usr/libexec/urlgrabber-ext-down

将这两个第一行的：#!/usr/bin/python 替换成#!/usr/bin/python2

安装 pip：

wget https://bootstrap.pypa.io/get-pip.py

python get-pip.py

ln -s /usr/local/bin/pip3 /usr/bin/pip
