My YunoHost server

Hardware: Old laptop or computer
YunoHost version: 11.2.8.2 (stable)
I have access to my server : Through SSH | through the webadmin | direct access via keyboard / screen | … (all of it)
Are you in a special context or did you perform some particular tweaking on your YunoHost instance ? : no
If yes, please explain: The only tweak I did was to add /var/www/pelican/comment as an External Mount on Nextcloud following this comment and referring to the pelican-themes and pelican-plugins in my home directory, but that should not affect anything.
If your request is related to an app, specify its name and version: pelican 4.8.0~ynh1

Description of my issue

In the process of migrating my old Pelican blog to YunoHost I am met with the challenge of adding Python modules/packages that are required for certain Pelican plugins that I depend on.

So I wonder what some of the best practices would be to install these modules and ideally how to keep them updated. I assume it will have to be in venv, but not sure. I kept it pretty messy before, TBH.

For context, what I currently get when I sudo /var/www/peclican/venv/bin/pelican /var/www/pelican/content/:

Description du problème

En migratant de mon ancient blog Pelican à YunoHost, j’ai un problème comment ajouter des modules Python, desquels certaines plugins Pelican, que j’utilise, ont besoin.

Ainsi, je vous commande des meilleures pratiques pour installer ces modules Python et, idéalement, comment les tenir à jour. Je croix que je dois utiliser venvpour ça, mais j’ai aucune idée. Précédemment, je l’ai gardé plutôt en désordre, pour être honnête.

Pour contexte, sudo /var/www/peclican/venv/bin/pelican /var/www/pelican/content/ me donne:

Try:

sudo yunohost app shell pelican
# the line above is equivalent to `cd /var/www/pelican && sudo -u pelican bash`
source venv/bin/activate
pip3 install bs4 piexif pillow
# line above to be tweaked accordingly

when done, exit to quit the terminal or deactivate to exit the python environment for Pelican.

Awesome, thanks. And for updating, same but pip3 install --upgrade when needed, or is is then handled automatically on each Pelican update?

You’re welcome! Right now the upgrade script does not handle upgrading the whole environment.

Got it. I’m not sure if it can be done safely and reliably, but if so, that would be really cool. If not, I’ll just try to remember to do it myself more regularly / when needed :slight_smile:
