[分享栈]centos7安装python3.8.5 1、切换到root账户2、更新yum源yum update中间有询问过程，直接y同意更新就好了。3、安装依赖项yum install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel libffi-devel gcc make4、下载python3.8.5wget -P /home https://cdn.npm.taobao.org/dist/python/3.8.5/Python-3.8.5.tgz5、解压cd /home && tar -zxvf Python-3.8.5.tgz6、配置编译cd Python-3.8.5 mkdir /usr/local/python3.8.5 ./configure --prefix=/usr/local/python3.8.5 ./configure --enable-optimizations 如果出现错误信息：SystemError: <built-in function compile> returned NULL without setting an error generate-posix-vars failed；则需要升级gcc版本，请先升级gcc版本，参考链接centos7安装gcc10.2.0。7、编译安装make && make install8、建立链接ln -s /usr/local/python3.8.5/bin/python3 /usr/bin/python3 ln -s /usr/local/python3.8.5/bin/pip3 /usr/bin/pip3如果提示链接已存在，删除原链接即可。9、查询版本python3 --version
