I have the following playbook:
---
- hosts: app
become: yes
tasks:
- name: Install MySQL-Python
yum: name=MySQL-python state=present
- name: Install Python Setup Tools
yum: name=python-setuptools state=present
- name: Install django
easy_install: name=django state=present
This fails with the error:
This version of Django requires Python 3.4, but you're trying to\ninstall it on Python 2.7.\n\nThis may be because you are using a version of pip that doesn't\nunderstand the python_requires classifier. Make sure you\nhave pip >= 9.0 and setuptools >= 24.2, then try again:\n\n $ python -m pip install --upgrade pip setuptools\n $ python -m pip install django\n\nThis will install the latest version of Django which works on your\nversion of Python. If you can't upgrade your pip (or Python), request\nan older version of Django:\n\n $ python -m pip install \"django<2\"\nerror: Setup script exited with 1\n"}
I followed this article to install Python 3 and also set python=python3, yet I am facing the same error message when I run the playbook.
Can anyone please suggest what to do? Also, I do I install a previous version of Django using Ansible?
I would use the pip module to install Django instead of easy_install. You can use executable to use the pip for Python 3.4. You can use version to specify which version you want to use - if you decide to use Python 2 you will need to install Django<2.
- name: Install django
pip:
name: django
executable: pip-3.4
version: 2.0.4
Note that MySQL-Python has not been supported in several years. It would be better to use the fork mysqlclient, which supports Python 3.
You should also consider installing your modules in a virtual environment.
