你好，我正在尝试安装ansible与pip使用流浪汉和ansible在Ubuntu服务器Trusty64。我使用roles来安装python3，安装ansible的角色是：

---
# tasks file for roles/ansible
- name: install pip3
  apt: name=python3-pip state=present
  tags: ansible

- name: install librerias dev
  apt: name=libssl-dev state=present
  tags: ansible

- name: install librerias essential
  apt: name=build-essential state=present
  tags: ansible

- name: install librerias libdev
  apt: name=libffi-dev state=present
  tags: ansible

- name: install librerias pydev
  apt: name=python-dev state=present
  tags: ansible

- name: install librerias pydev
  apt: upgrade=yes
  tags: ansible

- name: install setuptools
  command: pip3 install setuptools
  tags: ansible

- name: upgrade setuptools
  command: pip3 install --upgrade setuptools
  tags: ansible

- name: install ansible
  command: pip3 install ansible
  tags: ansible

在安装python3和pip3之后，安装ansible失败，并出现下一个错误追溯：

Python 3.5 or later is required",                                                                   
    "stderr_lines": [
        "Traceback (most recent call last):", 
        "  File \"/usr/bin/pip3\", line 5, in <module>", 
        "    from pkg_resources import load_entry_point", 
        "  File \"/usr/local/lib/python3.4/dist-packages/pkg_resources/__init__.py\", line 93, in <module>", 
        "    raise RuntimeError(\"Python 3.5 or later is required\")", 
        "RuntimeError: Python 3.5 or later is required"
    ], 
    "stdout": "", 
    "stdout_lines": []
}

我不明白为什么我也要解决这个问题，因为我已经安装了python3使用这个角色：

---
# tasks file for roles/python3

- name: aniadir repositorio
  apt_repository: 
   repo: ppa:deadsnakes/ppa
   state: present

- name: actualizar cache
  apt: update_cache=yes

- name: instalar python3
  apt: name=python3.7 state=present

我已经使用pip3安装setuptools并升级了它。我会很感激你的帮助。谢谢.
