pyenv離線安裝python各版本

1.問題描述：

可能是國內的網絡原因，在線用pyenv安裝python老是定住沒反應

[root@zabbix ~]# pyenv install 3.6.2
Downloading Python-3.6.2.tar.xz...
-> https://www.python.org/ftp/python/3.6.2/Python-3.6.2.tar.xz

2.安裝配置

安裝前需要在pyenv目錄下創建cache文件夾，沒有的情況

[root@zabbix ~]# cd ~/.pyenv/
[root@zabbix .pyenv]# mkdir cache

下載離線包利用wget，需要進入cache目錄下

[root@zabbix cache]# wget https://www.python.org/ftp/python/3.6.2/Python-3.6.2.tar.xz

然后查看目錄下有沒有python的tar包

[root@zabbix cache]# ls
Python-3.6.2.tar.xz

查看到已經下載成功以后再用pyenv安裝python

[root@zabbix ~]# pyenv install 3.6.2

Installed Python-3.6.2 to /root/.pyenv/versions/3.6.2

最后查看是否安裝成功

[root@zabbix ~]# pyenv versions
* system (set by /root/.pyenv/version)
  3.6.2
