1.备份原有源
tar -zcvf CentOS-bk.tar.gz /etc/yum.repos.d/CentOS-*
2.替换为阿里云源
curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
curl -o /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo
|
3.nameserver
vim /etc/resolv.conf
nameserver 8.8.8.8
nameserver 114.114.114.114
|
并执行
4.安装依赖
yum -y groupinstall "Development tools"
yum install -y ncurses-devel gdbm-devel xz-devel sqlite-devel tk-devel uuid-devel readline-devel bzip2-devel libffi-devel
yum install -y openssl-devel openssl11 openssl11-devel
|
指定编译版本
export CFLAGS=$(pkg-config --cflags openssl11)
export LDFLAGS=$(pkg-config --libs openssl11)
|
5.下载源码包并编译
tar xvzf Python-3.10.4.tgz
cd Python-3.10.4
./configure --enable-optimizations && make altinstall
/usr/local/bin/python3.10 --version
/usr/local/bin/pip3.10 --version
|
6.建立软连接
ln -sf /usr/local/bin/python3.10 /usr/bin/python3
ln -sf /usr/local/bin/pip3.10 /usr/bin/pip3
|
7.替换源
vim ~/.pip/pip.conf
[global]
index-url=https://pypi.tuna.tsinghua.edu.cn/simple/
extra-index-url=
http://pypi.douban.com/simple/
http://mirrors.aliyun.com/pypi/simple/
#proxy = [user:passwd@]proxy.server:port
[install]
trusted-host=
# pypi.tuna.tsinghua.edu.cn
# pypi.douban.com
mirrors.aliyun.com
ssl_verify: false
|
pip3 install --upgrade pip
|
9.尝试安装包到指定目录
