I'm trying to update our venv of ansible to a newer version on an older RHEL 7 box :), only it seems to fail for some unclear reasons in some python code.

Running python 3.6.8 on RHEL 7.9 (Maipo)

Any hints are most appreciated, TIA!

python is /opt/pjp_ansible/virtual_env/a2.9.27/bin/python
$ which pip
/opt/pjp_ansible/virtual_env/a2.9.27/bin/pip

  • https://stackoverflow.com/search?q=UnicodeEncodeError%3A+%27ascii%27+codec+can%27t+encode+character. Without looking at data and code ([mcve]), that's as far as it gets. – Ulrich Eckhardt Jun 27 '22 at 12:09
  • This is an encoding issue at Python's level. See https://stackoverflow.com/questions/57197059/unicodeencodeerror-ascii-codec-cant-encode-character-xe9-when-printing-in and https://github.com/pypa/pip/issues/10219#issuecomment-887337037 – β.εηοιτ.βε Jun 27 '22 at 12:09
  • Thanks but it seems that ansible +2.9.10 requires python +3.7/8, hence looking into running pyenv to have multiple python version on the same box :) – Steffen Winther Sørensen Jun 30 '22 at 08:56

found this: realpython.com/intro-to-pyenv which enabled me to create a newer python env and apply in multiple virtual env each with their version of ansible compiled from sources.
