centos7中安装python3

Posted 2022-10-06 xiujin

1.安装相应的编译工具

在root用户下(不要用普通用户,麻烦),全部复制粘贴过去,一次性安装即可.

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 libffi-devel -y
yum install zlib* -y

2.下载安装包

wget wget https://www.python.org/ftp/python/3.7.2/Python-3.7.2.tar.xz

3.解压

tar -xvJf  Python-3.7.2.tar.xz

4.创建编译安装目录

mkdir /usr/local/python3 

5.安装

cd Python-3.7.2
./configure --prefix=/usr/local/python3
make && make install

6.创建软链接

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

7.验证是否成功

python3 -V
pip3 -V

8.报错处理
