报错原因是由于本机中缺少gcc编译环境，2种解决方式

1、通过yum安装gcc编译环境：yum install -y gcc

2、本机没有安装yum功能，可下载gcc安装包：https://gcc.gnu.org/

[root@hadoop1 Python-3.6.4]# yum install -y gcc

[root@hadoop1 Python-3.6.4]# yum install -y gcc


已安装:
  gcc.x86_64 0:4.4.7-18.el6_9.2                                                                                 

作为依赖被安装:
  cloog-ppl.x86_64 0:0.15.7-1.2.el6        cpp.x86_64 0:4.4.7-18.el6_9.2        mpfr.x86_64 0:2.4.1-6.el6       
  ppl.x86_64 0:0.10.2-11.el6              

作为依赖被升级:
  libgcc.x86_64 0:4.4.7-18.el6_9.2                       libgomp.x86_64 0:4.4.7-18.el6_9.2                      

完毕！
[root@hadoop1 Python-3.6.4]#

重新执行命令 添加配置

[root@hadoop1 Python-3.6.4]# ./configure --prefix=/usr/local/python3

[root@hadoop1 Python-3.6.4]# ./configure --prefix=/usr/local/python3

If you want a release build with all stable optimizations active (PGO, etc),
please run ./configure --enable-optimizations


[root@hadoop1 Python-3.6.4]#

六、编译源码

[root@hadoop1 Python-3.6.4]# make

七、执行安装

[root@hadoop1 Python-3.6.4]# make install

八、将python3的目录复制到/usr/bin/目录下

[root@hadoop1 /]# cp /usr/local/python3/ /usr/bin/
[root@hadoop1 /]# 

[root@hadoop1 bin]# mv python3 python364

[root@hadoop1 bin]# ln -s /usr/local/python3/bin/python3 /usr/bin/python3

十、配置环境变量

[root@hadoop1 bin]# vi /etc/profile

#Python3.6.4
PATH=$PATH:$HOME/bin:/usr/bin/python3/bin
export PATH

修改完记得执行行下面的命令，让上一步的修改生效：

[root@hadoop1 bin]# source /etc/profile

十一、检查验证

[root@hadoop1 bin]# python3 -V
Python 3.6.4
[root@hadoop1 bin]# 

十二、安装模块

[root@hadoop1 bin]# pip3 install paramiko
bash: /usr/bin/pip3: 没有那个文件或目录

报错么有这个命令

建立pip3的软连接

[root@hadoop1 bin]# ln -s /usr/local/python3/bin/pip3.6 /usr/bin/pip3

重新安装模块

[root@hadoop1 bin]# pip3 install paramiko
Collecting paramiko
  Could not find a version that satisfies the requirement paramiko (from versions: )
No matching distribution found for paramiko
You are using pip version 9.0.1, however version 9.0.3 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.
