Hello, I try to setup a tile server with this tutorial: https://switch2osm.org/serving-tiles/manually-building-a-tile-server-20-04-lts/. The process can not be continued at SHAPEFILE DOWNLOAD, because module YAML is missing. I´m not familiar with python, what can I do? Error hits here:

scripts/get-external-data.py

Thx and Regards

Could you provide a full output of the error?

You should be able to install a system wide version with sudo apt install python3-yaml.

I've updated https://switch2osm.org/serving-tiles/manually-building-a-tile-server-20-04-lts/ to include python3-yaml . It was present in the Debian 11 guide but not the Ubuntu 20.04 one.

What software is needed changed as what's packaged in various OSes, and also in things like OSM Carto itself, change ver time.

I also tried to install YAML by: /usr/bin/python -m pip install pyyaml

I found that here (last post): https://github.com/yaml/pyyaml/issues/291

So PIP seems also not beeing installed. What went wrong? I missed no line of the tutorial.

No, you didn't. A dependency (that wasn't previously needed but now is) was missing. I've added it at https://github.com/switch2osm/switch2osm.github.io/pull/170 .

The switch2osm guides use the package manager in your OS where possible, in this case Ubuntu's "apt". These days every 2-bit language has at least one package manager (python has "pip" and "cpan", node.js has "npm" and "yarn"). These guides don't use those but instead uses packages bundled (and tested) by Ubuntu.

I solved this my manually adding pip3 and after that by additionally install of pyyaml and requests. The card works now as expected. Thx

sudo apt install python3-pip
/usr/bin/python3 -m pip install pyyaml
/usr/bin/python3 -m pip install requests
/usr/bin/python3 -c 'import yaml'
