Ansible - falha na instalação do pip3

Estou tentando instalar o Ansible no CentOS 7 e tenho o Ansible configurado para usar o Python 3. Tenho o Python2 e o Python3 instalados.

[root@ansible1 ~]# python --version
Python 2.7.5
[root@ansible1 ~]# python3 --version
Python 3.6.8

Se eu instalar o Ansible usando yum install ansible, o ansible --versioncomando mostrará que o Ansible está configurado para usar o Python 2.7.5. Eu desinstalo o ansible ( yum remove ansible);

[root@ansible1 ~]# ansible --version
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 = /bin/ansible
  python version = 2.7.5 (default, Aug  7 2019, 00:51:29) [GCC 4.8.5 20150623 (Red Hat 4.8.5-39)]

De acordo com https://docs.ansible.com/ansible/latest/reference_appendices/python_3_support.html :

A maneira mais fácil de executar /usr/bin/ansible no Python 3 é instalá-lo com a versão Python3 do pip. Isso fará com que o padrão /usr/bin/ansible seja executado com Python3

Eu tenho a versão 9.0.3 do pip instalada.

[root@ansible1 ~]# pip3 --version
pip 9.0.3 from /usr/lib/python3.6/site-packages (python 3.6)

Seguindo a documentação do Ansibles, eu emito pip3 install ansiblepara instalar o Ansible usando pip3.

[root@ansible1 ~]# pip3 install ansible
WARNING: Running pip install with root privileges is generally not a good idea. Try `pip3 install --user` instead.

Aqui está a saída do pip3 show ansiblecomando.

[root@ansible1 ~]# pip3 show ansible
Name: ansible
Version: 2.9.12
Summary: Radically simple IT automation
Home-page: https://ansible.com/
Author: Ansible, Inc.
Author-email: [email protected]
License: GPLv3+
Location: /usr/local/lib/python3.6/site-packages
Requires: jinja2, PyYAML, cryptography

No entanto, o ansible --versioncomando retorna o seguinte.

-bash: /bin/ansible: No such file or directory

Da mesma forma /usr/bin/ansible --version,:

-bash: /usr/bin/ansible: No such file or directory

O pip show ansiblecomando mostra que o local é /usr/local/lib/python3.6/site-packages/ansible. Este diretório existe e contém muitos arquivos e pastas, mas nenhum arquivo de configuração específico do Ansible (por exemplo, ansible.cfg) ou arquivos binários (por exemplo, ansible) que podem ser usados ​​(o melhor que posso dizer).
