django - 怎么: django_manage in ansible with Python3

Question

我正在关注 django manage.py 模块
http://docs.ansible.com/django_manage_module.html

例如我的一项任务看起来像 -

- name: Django migrate
  django_manage: command=migrate
                 app_path={{app_path}}
                 settings={{django_settings}}
  tags:
    - django

这适用于 python2(默认在 ubuntu 中)但是当我尝试使用 python3-django 项目时它会抛出错误

failed: [123.456.200.000] => (item=school) => {"cmd": "python manage.py makemigrations --noinput school --settings=myproj.settings.production", "failed": true, "item": "school", "path": "/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games", "state": "absent", "syspath": ["/home/ubuntu/.ansible/tmp/ansible-tmp-1432039779.41-30449122707918", "/usr/lib/python2.7", "/usr/lib/python2.7/plat-x86_64-linux-gnu", "/usr/lib/python2.7/lib-tk", "/usr/lib/python2.7/lib-old", "/usr/lib/python2.7/lib-dynload", "/usr/local/lib/python2.7/dist-packages", "/usr/lib/python2.7/dist-packages"]}
msg: 
:stderr: Traceback (most recent call last):
  File "manage.py", line 8, in <module>
    from django.core.management import execute_from_command_line
ImportError: No module named django.core.management

从这个错误看来，Ansible 默认使用 Python2。我们可以将其更改为 python3 或任何其他解决方法吗？

PS:pip freeze 确保已安装 django 1.8(对于使用 pip3 的 python3)

建议:
当我运行 ubuntu@ubuntu:/srv/myproj$ python3 manage.py migrate 它工作正常。所以我正在考虑直接传递命令
就像是

 - name: Django migrate
   command: python3 manage.py migrate
   tags:
     - django

但是如何传递项目路径或 manage.py 文件的路径，只有一个选项可以传递设置，例如 --settings=myproject.settings.main 。

我们可以通过直接命令吗？

来自 Ansible 网站 http://docs.ansible.com/intro_installation.html

Python 3 is a slightly different language than Python 2 and most Python programs (including Ansible) are not switching over yet. However, some Linux distributions (Gentoo, Arch) may not have a Python 2.X interpreter installed by default. On those systems, you should install one, and set the ‘ansible_python_interpreter’ variable in inventory (see Inventory) to point at your 2.X Python. Distributions like Red Hat Enterprise Linux, CentOS, Fedora, and Ubuntu all have a 2.X interpreter installed by default and this does not apply to those distributions. This is also true of nearly all Unix systems. If you need to bootstrap these remote systems by installing Python 2.X, using the ‘raw’ module will be able to do it remotely.
