蓝奏云下载地址:Python-3.7.12及依赖包

一、环境

1. 系统：CentOS 7
2. 用户：ROOT
3. Python版本：python3.7.12

二、安装

1. 登录到centOS机器，新建文件夹

mkdir -p /usr/local/python3

2. 将安装包和依赖包里的文件上传至/usr/local/python3
3. 进入目录

cd /usr/local/python3/

4. 安装依赖

# 如遇到安装失败，可以添加强制安装参数 --nodeps --force
例： rpm -ivh zlib-devel-1.2.7-17.el7.x86_64.rpm --nodeps --force

#安装依赖包 zlib-devel
rpm -ivh zlib-devel-1.2.7-17.el7.x86_64.rpm
#安装依赖包 bzip2-devel
rpm -ivh bzip2-devel-1.0.6-13.el7.x86_64.rpm
#安装依赖包 epel-release
rpm -ivh epel-release-7-11.noarch.rpm
#安装依赖包 ncurses-devel
rpm -ivh ncurses-devel-5.9-13.20130511.el7.x86_64.rpm
# 安装依赖包 gcc（一定要按照以下的顺序进行安装）
rpm -ivh mpfr-3.1.1-4.el7.x86_64.rpm
rpm -ivh libmpc-1.0.1-3.el7.x86_64.rpm
rpm -ivh kernel-headers-3.10.0-514.el7.x86_64.rpm
rpm -ivh glibc-headers-2.17-157.el7.x86_64.rpm
rpm -ivh glibc-devel-2.17-157.el7.x86_64.rpm
rpm -ivh cpp-4.8.5-11.el7.x86_64.rpm
rpm -ivh gcc-4.8.5-11.el7.x86_64.rpm
# 安装依赖包 gcc-c+
rpm -ivh libstdc++-4.8.5-11.el7.x86_64.rpm
rpm -ivh libstdc++-devel-4.8.5-11.el7.x86_64.rpm
rpm -ivh gcc-c++-4.8.5-11.el7.x86_64.rpm

5. 进行解压

tar -xzvf Python-3.7.12.tgz

6. 进入解压路径

cd /usr/local/python3/Python-3.7.12

7. 设置安装路径

./configure --prefix=/usr/local/python3.7 --enable-shared

make && make install

ln -s /usr/local/python3.7/bin/python3 /usr/bin/python3

echo "/usr/local/python3.7/lib" > /etc/ld.so.conf.d/python3.7.conf

ldconfig

8. 检查Python3.7.12是否安装成功

python3 -V

显示如下图，说明成功；

python3

9. 删除安装包以及依赖包

rm -rf  /usr/local/python3

三、安装pip3

1. python 3.7.12中自带了pip，所以只需要建立链接就行

ln -s /usr/local/python3.7/bin/pip3.7 /usr/bin/pip3

2. 检查pip是否安装成功

pip3 -V
