我检查了 this post并在两个答案中都遵循了修复，但都没有奏效。我正在开一个新帖子，部分原因是因为我得到了一个稍微不同的错误，即使问题可能是相同的。

Ansible 主机:

$ ansible --version
ansible 2.1.0.0
  config file = /etc/ansible/ansible.cfg
  configured module search path = Default w/o overrides

目标客户端 myserver:

$ pip list | egrep 'six|docker|websocket_client'
docker-py (1.2.3)
six (1.10.0)

test.yml:

---
- hosts: myserver
  remote_user: root
  tasks:
  - name: stop any running docker registries
    docker_container:
      name: registry
      state: stopped
...

Ansible 服务器(ansible-playbook 别名为 ap):

$ ap -vvvv test.yml

输出:

(可能是无关的输出，已剪断):

(相关错误):

“导入 docker-py 失败 - 无法导入名称 NotFound。尝试 pip install docker-py”}

根据引用帖子中的第一个答案，当我将 docker-py 模块降级到 1.1.0 时，我得到了同样的错误。我还尝试对目录进行 chmod，但没有任何区别:

(/usr/lib/python2.7/site-packages) myserver$ ls -lad docker*
drwxr-xr-x. 6 root root 4096 Jul  4 10:57 docker/
drwxr-xr-x. 2 root root 4096 Jul  4 10:57 docker_py-1.2.3-py2.7.egg-info/

来自 chmod -R go+rx docker*.

有人见过这个吗？我曾尝试使用 pip ansible 模块来安装模块，然后在手动删除它们后，像引用的帖子中那样手动重新安装它们。我也在使用 2.1.0.0。如您所见，这应该可以解决此问题。

最佳答案

这是因为ansible使用的新版本的python模块docker和docker-py不兼容。我不得不恢复并明确指定以下版本的 PIP 包:

• docker :2.0.0
• docker-py: 1.10.6

这些的示例剧本任务:

- name: install certain python modules for docker
  pip:
    name: "{{ item.name }}"
    version: "{{ item.version }}"
    state: present
  with_items:
  - { name: docker, version: 2.0.0 }
  - { name: docker-py, version: 1.10.6 }

从那时起，我所有的剧本都运行良好。

关于python - 即使安装了 Ansible 也无法导入 docker-py，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/38181433/
