源码编译安装 Python

1、卸载自带的 Python（切记不要随便卸载自带 python，我在 openeuler-20.03-sp3 上卸载的时候把 yum 给卸载没了，安装完后配置软连接就好，除非你知道你自己在干什么）

yum remove python3
rpm -qa | grep python3 | xargs rpm -ev --allmatches --nodeps
whereis python3 | xargs rm -frv

2、下载解压最新 Python 源码

curl -O https://www.python.org/ftp/python/3.10.6/Python-3.10.6.tgz
tar -zxvf Python-3.10.6.tgz

3、安装编译需要的包

yum -y install gcc zlib* libffi-devel openssl-devel make

4、源码编译安装

cd Python-3.10.6/
./configure --prefix=/usr/local/python3 --enable-optimizations
make 
make install

5、创建软连接

rm -rf /usr/bin/python3 /usr/bin/python
ln -s /usr/local/python3/bin/python3 /usr/bin/python3
ln -s /usr/local/python3/bin/python3 /usr/bin/python
rm -rf /usr/bin/pip3 /usr/bin/pip
ln -s /usr/local/python3/bin/pip3 /usr/bin/pip3
ln -s /usr/local/python3/bin/pip3 /usr/bin/pip

6、添加 python 库配置信息

echo "/usr/local/python3/lib" >> /etc/ld.so.conf.d/python3.conf
ldconfig

7、检查新版本

python3 --version
pip3 --version

8、可能遇到的错误

Could not import runpy module

需要安装依赖

yum install yum-utils
yum-builddep python

然后执行make

make clean
make
make install
