2.安装Python 3.5.2

前面，我们已经了解了怎么安装Pyenv的安装，本章我们学习如何使用pyenv安装Python 3.5.2。

1.获取程序包

[root@centos7 ~]# mkdir ./.pyenv/cache
[root@centos7 ~]# wget http://7d9qvq.com1.z0.glb.clouddn.com/Python-3.5.2.tgz
[root@centos7 ~]# mv Python-3.5.2.tgz  ./.pyenv/cache/Python-3.5.2.tar.gz

2.解决依赖

[root@centos7 ~]# yum install -y gcc make patch
[root@centos7 ~]# yum -y install gdbm-devel openssl-devel sqlite-devel readline-devel zlib-devel bzip2-devel

3.安装3.5.2

这个过程有点漫长，请耐心等待...

[root@centos7 ~]# pyenv  install 3.5.2

4.验证是否已经共存了连个pyenv系统

[root@centos7 ~]# pyenv  versions
* system (set by /root/.pyenv/version)
