安装python3.7.0的步骤

1）首先确认安装gcc编译器

gcc有些系统版本已经默认安装，通过 gcc --version 查看，若没安装，先安装gcc.

[root@localhost ~]#yum -y install gcc

2）安装其它依赖包

[root@localhost ~]#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

（注：不要缺少，否则有可能安装python出错，python3.7.0以下的版本可不装 libffi-devel ）

3）建立一个空文件夹，用于存放python3程序 [root@localhost ~]#mkdir /usr/local/python3

[root@localhost ~]#cd /usr/local/python3

4）下载python3.7的包 [root@localhost

https://www.python.org/ftp/python/3.7.0/Python-3.7.0.tgz

python3]#wget

[root@localhost python3]#tar -zxvf Python-3.7.0.tgz

5、执行配置文件，编译，编译安装

[root@localhost python3]#cd Python-3.7.0

[root@localhost Python-3.7.0]#./configure --prefix=/usr/local/python3

[root@localhost Python-3.7.0]#make && make install

安装完成没有提示错误便安装成功了 7、建立软连接 [root@localhost /usr/bin/python3

Python-3.7.0]#ln

-s

/usr/local/python3/bin/python3.7

[root@localhost /usr/bin/pip3

Python-3.7.0]#ln -s /usr/local/python3/bin/pip3.7

8、测试一下python3是否可以用 [root@localhost Python-3.7.0]#cd

[root@localhost ~]# python3
