[英]How to install ansible using ansible and pip
Hi I'm trying to install ansible with pip using vagrant and ansible in a ubuntu server Trusty64. Hi I'm trying to install ansible with pip using vagrant and ansible in a ubuntu server Trusty64. I used roles to install python3 and in the role to install ansible is:
我使用角色安装 python3 并在角色中安装 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
After python3 is installed and pip3 the installation fails installing ansible with the next error traceback:安装 python3 和 pip3 后,安装 ansible 安装失败,并出现下一个错误回溯:
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": []
}
And I cannot see why should I too to solve this because I already have installed python3 using this role:而且我不明白为什么我也应该解决这个问题,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
and I already used pip3 to install setuptools and to upgrade it.我已经使用 pip3 来安装 setuptools 并对其进行升级。 I would appreciate your help.
我会很感激你的帮助。 Thanks.
谢谢。
According to this answer , you need to add:根据this answer ,您需要添加:
- name: Select python3.7 as default python3
alternatives:
name: python3
path: /usr/bin/python3.7
As you can see in the error, Ansible tries to install Ansible with Python 3.4: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 is the default Python 3 for your installation. Python 3.4 是您安装的默认 Python 3。 Installing Python 3.7 only installs
python3.7
but does not make it the default Python 3. To do this, you must explicitly tell the system to use python3.7
when calling python3
, using the alternatives system .安装 Python 3.7 仅安装
python3.7
但不会使其成为默认 Python 3. 为此,您必须在调用python3
时明确告诉系统使用python3.7
,使用替代 system 。
