Ansible - pip3 安装失败

我正在尝试在 CentOS 7 上安装 Ansible，并将 Ansible 配置为使用 Python 3。我已经安装了 Python2 和 Python3。

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

如果我使用 安装 Ansible yum install ansible，该ansible --version命令显示 Ansible 已配置为使用 Python 2.7.5。我卸载 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)]

根据https://docs.ansible.com/ansible/latest/reference_appendices/python_3_support.html：

在 Python 3 下运行 /usr/bin/ansible 最简单的方法是使用 Python3 版本的 pip 安装它。这将使默认的 /usr/bin/ansible 与 Python3 一起运行

我安装了 9.0.3 版本的 pip。

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

按照 Ansibles 文档，我pip3 install ansible使用 pip3 安装 Ansible。

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

这是pip3 show ansible命令的输出。

[root@ansible1 ~]# pip3 show ansible
Name: ansible
Version: 2.9.12
Summary: Radically simple IT automation
Home-page: https://ansible.com/
Author: Ansible, Inc.

Location: /usr/local/lib/python3.6/site-packages
Requires: jinja2, PyYAML, cryptography

但是，该ansible --version命令返回以下内容。

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

同样，/usr/bin/ansible --version：

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

该pip show ansible命令显示位置是/usr/local/lib/python3.6/site-packages/ansible。该目录存在，并且包含许多文件和文件夹，但没有可以使用的 Ansible 特定配置文件（例如 ansible.cfg）或二进制文件（例如 ansible）（我能说的最好）。
