如何使用ansible和pip安装ansible
提问于 2020-05-01 02:46:28
您好，我正在尝试用pip在ubuntu服务器Trusty64中使用vagrant和ansible来安装ansible。我使用角色来安装python3，在角色中安装ansible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在安装了python3和pip3之后，安装失败并返回下一个错误回溯：
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，因为我已经使用这个角色安装了python3：
---
# 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安装了setuptools并对其进行了升级。我将非常感谢你的帮助。谢谢。

根据this answer的说法，你需要添加：
- name: Select python3.7 as default python3
alternatives:
name: python3
path: /usr/bin/python3.7正如您在错误中看到的，Ansible尝试使用Python 3.4安装Ansible：
/usr/local/lib/python3.4/dist-packages/pkg_resources/__init__.py
Python 3.4是您安装的默认Python 3。安装Python3.7只会安装python3.7，但不会将其设置为默认的Python3。为此在调用 python3 时，您必须明确告诉系统使用 python3.7，使用alternatives system。
