Centos7安装python3和pip3

前言

为甚么安装python3和pip3，因为20年py2就不跟新了，所以提前跑路升级python3，并汇总了我的安装过程，希望能给大家一点帮助。

安装

依赖

# 防止ImportError: cannot import name 'HTTPSHandler'
sudo yum install openssl-devel -y 
# 防止ImportError: cannot import name 'zlib'
sudo yum install zlib-devel -y

Python3安装

wget --no-check-certificate https://www.python.org/ftp/python/3.6.0/Python-3.6.0.tgz

tar -xzvf Python-3.6.0.tgz 

cd Python-3.6.0

sudo ./configure --prefix=/usr/local/python3/ --with-zlib=/usr/include --enable-loadable-sqlite-extensions

sudo make && make install
sudo ln -s /usr/local/python3/bin/python3 /usr/local/bin/python3

setuptools安装

wget --no-check-certificate https://pypi.python.org/packages/source/s/setuptools/setuptools-19.6.tar.gz#md5=c607dd118eae682c44ed146367a17e26 

tar -zxvf setuptools-19.6.tar.gz 
cd setuptools-19.6
sudo python3 setup.py build 
sudo python3 setup.py install

pip3安装

wget --no-check-certificate https://pypi.python.org/packages/source/p/pip/pip-8.0.2.tar.gz#md5=3a73c4188f8dbad6a1e6f6d44d117eeb 

tar -zxvf pip-8.0.2.tar.gz 
cd pip-8.0.2 
sudo python3 setup.py build 
sudo python3 setup.py install
sudo ln -s /usr/local/python3.4/bin/pip3 /usr/bin/pip3

建议把pip和python分别指向pip3和python3！
