Installation de Python 3.9.12 lors de l'installation de INDICO3

Lors de la procédure d’installation d’INDICO 3, je n’arrive pas à installer Python 3.9.12. je tombe toujours en error.
Je joins la copie d’écran.
Pourriez-vous m’aider.

Bonne journée.

Hi, please check the log file mentioned in the yellow part of the error message. It may contain more useful information on why building Python filed.

PS: Considering that this forum is very international (and probably just a fraction of the people here speak/understand French), I think using English here would be better…

Thank for your prompt reponse. I join de requested file.

To me it looks fine now. Did pyenv install ... fail with some message?

This, the messages obtained

yum install -y libjpeg-turbo-devel libxslt-devel libxml2-devel libffi-devel pcre-devel libyaml-devel zlib-devel bzip2 bzip2-devel readline-devel sqlite sqlite-devel openssl-devel xz xz-devel libffi-devel findutils libuuid-devel
/usr/pgsql-13/bin/postgresql-13-setup initdb

Are you sure you executed this step from the setup guide? It seems like you’re missing things like openssl which should be installed by this command…

It’s working !!!
Thank you guy :slight_smile:

Thank you.

Sounds like postgresql13-devel is missing… (another package that’s installed during the “Install Packages” step of the setup guide)
