CentOS中python的安装

1.安装依赖

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 libffi-devel

2.下载包

python官网

wget https://www.python.org/ftp/python/3.8.5/Python-3.8.5.tgz

3.解压

tar -zxvf Python-3.8.5.tgz

4.安装

cd Python-3.8.5
./configure --prefix=/usr/local/python3
make && make install

如果出现"make: *** 没有指明目标并且找不到 makefile。 停止。" 可以先执行一下 ./configure,再make, 再make install

5.建立软连接

ln -s /usr/local/python3/bin/python3.8 /usr/bin/python
ln -s /usr/local/python3/bin/pip3.8 /usr/bin/pip
