python - 即使已安装Ansible也无法导入docker-py(Ansible 2.3.0.0)

Question

我遇到的volvox遇到了同样的问题，后者曾提出原始问题，但当我使用answer从anoxis到他的帖子中的建议时，却遇到了Ansible 2.3.0.0。

重现步骤:

我创建了一个新的VirtualEnv:

zoidberg:foley chris$ virtualenv ansible-test
New python executable in /Users/chris/src/hc/foley/ansible-test/bin/python2.7
Also creating executable in /Users/chris/src/hc/foley/ansible-test/bin/python
Installing setuptools, pip, wheel...done.

已安装Ansible:

(ansible-test) zoidberg:foley chris$ pip install ansible

检查版本:

(ansible-test) zoidberg:foley chris$ ansible --version
ansible 2.3.0.0
  config file =
  configured module search path = Default w/o overrides
  python version = 2.7.13 (default, May 14 2017, 22:38:03) [GCC 4.2.1 Compatible Apple LLVM 8.1.0 (clang-802.0.42)]

安装了此答案中建议的docker和docker-py版本:

(ansible-test) zoidberg:foley chris$ pip list | grep docker
DEPRECATION: The default format will switch to columns in the future. You can use --format=(legacy|columns) (or define a format=(legacy|columns) in your pip.conf under the [list] section) to disable this warning.
docker (2.0.0)
docker-py (1.10.6)
docker-pycreds (0.2.1)

但是我仍然遇到同样的错误:

(ansible-test) zoidberg:foley chris$ ansible-playbook -i inventory/local build.yml -vvvv
No config file found; using defaults

           PRIVATE_REPO_PASSWORD: "{{ PRIVATE_REPO_PASSWORD }}"
      delegate_to: localhost

而我的库存:

(ansible-test) zoidberg:foley chris$ cat inventory/local
[localhost]
127.0.0.1 ansible_connection=local

知道我在做什么错吗？

谢谢

Answer 1

多亏了Appleman上的Ansible GitHub issues page，我对此有了一个解决方案，该解决方案可以在Python 3中运行Ansible:

foley chris$ ansible-playbook -i inventory/local build.yml -e ansible_python_interpreter="/usr/local/bin/python3"

PLAY [Build foley docker images] ***********************************************************************************************************
