centos8 安装python 3.8.1教程

免费部落这段时间安装python 3.6以上的版本,试了很多网上的资料,总会遇到多多少少的问题,比如安装好,却提示找不到python,或者能安装成功,但pip无法使用。

所以在这里,把成功安装的过程记录在下面,以供参考:

安装准备:(cnetos安装python3.6 也可以参考)

yum -y install wget

yum -y install setup

yum -y install perl

yum install openssl-devel -y

yum install zlib-devel -y

安装:

yum -y groupinstall "Development tools"

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

yum install -y libffi-devel zlib1g-dev

yum install zlib* -y

yum install libffi-devel -y

wget https://www.python.org/ftp/python/3.8.1/Python-3.8.1.tar.xz

tar -xvJf Python-3.8.1.tar.xz

mkdir /usr/local/python3

cd Python-3.8.1

./configure --prefix=/usr/local/python3 --enable-optimizations --with-ssl

make && make install

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

ln -s /usr/local/python3/bin/pip3 /usr/local/bin/pip3

pip3 install --upgrade pip

期间遇见安装“pip3 install --upgrade pip”时提示SSL问题:

 rpm -aq|grep openssl 
yum install openssl-devel -y

然后再重新配适

./configure --prefix=/usr/local/python3 --enable-optimizations --with-ssl 
make && make install
