前言：ansible运行报错
/usr/lib64/python2.7/site-packages/cryptography/__init__.py:39: CryptographyDeprecationWarning: Python 2 is no longer supported by the Python core team. Support for it is now deprecated in cryptography, and will be removed in a future release. CryptographyDeprecationWarning
环境说明：
主机名操作系统版本python版本python3版本pip版本pip3版本ansibleCentos 7.6.1810Python 2.7.5Python 3.6.8pip 20.2.2(python 2.7)pip 20.2.2(python 3.6)
一、安装ansible
[root@ansible ~]# yum -y install https://releases.ansible.com/ansible/rpm/release/epel-7-x86_64/ansible-2.9.9-1.el7.ans.noarch.rpm
使用yum方式安装ansible，指定安装ansible版本为2.9.9
二、运行ansible
运行ansible时有如下提示
[root@ansible ~]# ansible --version/usr/lib64/python2.7/site-packages/cryptography/__init__.py:39: CryptographyDeprecationWarning: Python 2 is no longer supported by the Python core team. Support for it is now deprecated in cryptography, and will be removed in a future release. CryptographyDeprecationWarning,ansible 2.9.10 config file = /etc/ansible/ansible.cfg configured module search path = [u'/root/.ansible/plugins/modules', u'/usr/share/ansible/plugins/modules'] ansible python module location = /usr/lib/python2.7/site-packages/ansible executable location = /usr/bin/ansible python version = 2.7.5 (default, Apr  2 2020, 13:16:51) [GCC 4.8.5 20150623 (Red Hat 4.8.5-39)]
虽然这个提示不影响使用，但是对于有强迫症的我来说是不可接受的
三、问题解决
1.卸载ansible
[root@ansible ~]# yum remove ansible
2.使用pip3重新安装ansible
[root@ansible ~]# pip3 install xlrd -i http://pypi.douban.com/simple --trusted-host pypi.douban.com[root@ansible ~]# mkdir ~/.pip[root@ansible ~]# touch ~/.pip/pip.conf[root@ansible .pip]# more pip.conf[global]index-url = http://pypi.douban.com/simple[install]trusted-host = pypi.douban.com[root@ansible .pip]# pip3 install ansible==2.9.9
使用pip3重新安装ansible，重装后问题解决
