无法安装ansible awx

我正在尝试安装AWX，但由于以下错误而失败

版本信息

ansible --version
ansible 2.4.0.0
  config file = /etc/ansible/ansible.cfg
  configured module search path = [u'/root/.ansible/plugins/modules', u'/usr/share/ansible/plugins/modules']

docker--版本

有人能告诉我我做错了什么吗

还有一种方法可以在虚拟机中安装AWX，而无需docker/container，就像其他应用程序一样吗？

Ansible告诉您：

python version = 2.6.6

Requirement already satisfied: docker-py in /usr/lib/python3.6/site-packages

皮普告诉你：

python version = 2.6.6

Requirement already satisfied: docker-py in /usr/lib/python3.6/site-packages

比较上面的Python版本号并修复。

主题外问题？这是怎么离题的？好吧，我没有意识到这一点。我将删除以下问题：）
