linux 安装python3.x

 

1、自己装好linux，配置好linux

我的系统用的是centos7
2、

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 gcc*

 

3、下载python tar包
https://www.python.org/ftp/python/
选择自己喜欢的小版本


4、把下载好的python包放进/usr/local文件夹里进行解压
最后进行编译
编译命令：
./configure --prefix=/usr/local/python3
再执行下面命令：
make && make install


5、建立软链接

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

 

 

6、测试python是否能用

[root@mini Python-3.7.0]# python3
