我有一台搬瓦工VPS,系统是CentOS Linux release 7.5,已经自己按照该页面: https://dev.to/lechatthecat/how-to-install-python3-in-centos7-1bk6 安装了python3.6,
输入python3.6 --version显示Python 3.6.5
输入python3.6 -m pip --version显示pip 9.0.1 from /usr/lib/python3.6/site-packages (python 3.6)
然后使用了 compgen -c | grep "^python" 这个命令查看了一下目前支持的python版本,显示这些:
python3.6m-x86_64-config
python3.6
python
python3.6-config
python2
python3.6m-config
python-config
python2.7-config
python3.6m
python2.7
python2-config
但是安装你的脚本的时候还是显示python3: command not found,想问下这个是怎么回事呢?

知道问题出在哪了,还要添加软链接到python3,让系统默认调用python3.6,不过还要单独更改yum配置，因为其要用到python2才能执行，否则会导致yum不能正常使用.
希望脚本里能添加检测到是centos7之后自动编译安装python新版本并自动修正yum配置的设置,网上有关这方面的教程挺多的,也幸亏是教程多,不然我这个小白真的搞不定,
如果作者觉得麻烦的话也建议不要在脚本页面中写这个脚本支持centos7,让之后的人少走弯路

因为脚本默认是自动安装python3.4的，自动在线装，而不是自己手动去编译安装python3.6，自己手动装是另一回事了

我是先装过一次脚本了,第一次报错显示python3: command not found,然后看了下ISSUES里这个现象在centos7上很普遍, 所以才开始自己找centos7安装python3的教程的

编译安装是不可能的，会导致一堆低配小鸡安装不上(无编译环境)，假如在线安装python3.6也是这样，只能顾及最大限度普及安装也不失太落后(不会是用python2)

我用的vultr centos7来测，还没用过板瓦工的centos7，回去有空测试下，建议用debian9装应该没问题

@sdshdv 可以试下这个http://blog.51cto.com/wenguonideshou/2083301, 不编译安装而是yum, 看下脚本后面能不能全平台上python3.6, 今天会优化下python3的安装

@sdshdv 改了centos7的py3安装方法，centos7默认装py3.6, 实测搬瓦工centos7可以了，感谢反馈😄
