python3.10安装

wget https://www.python.org/ftp/python/3.10.9/Python-3.10.9.tgz

cd /usr/local/

mkdir -pv python310

tar  -zxvf  Python-3.10.9.tgz

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 gcc make

./configure --prefix=/usr/local/python310

make

make install

vi /etc/profile

export PATH=/usr/local/python310/bin:$PATH

source  /etc/profile

[root@k8-node bin]# python3 --version
Python 3.10.9
[root@k8-node bin]# pip3 --version
pip 22.3.1 from /usr/local/python310/lib/python3.10/site-packages/pip (python 3.10)

pip指定国内的源

 pip install python-gitlab -i  http://mirrors.aliyun.com/pypi/simple/ --trusted-host mirrors.aliyun.com

  pip3 install python-gitlab -i  http://mirrors.aliyun.com/pypi/simple/ --trusted-host mirrors.aliyun.com

  pip3 install --upgrade pip

环境变量每次输入python默认进入python2.7, 这个继续修改

 mv /usr/bin/python /usr/bin/python_2.7

ln -s  /usr/local/python310/bin/python3   /usr/bin/python

这个修改会影响到yum

解决方法：

vi /usr/bin/yum  查看yum内容

输入i 将第一行

#! usr/bin/python改为如下

#!/usr/bin/python_2.7
