Installing GNU Health: Method Not Allowed

Hello, I’m also trying to install GNU Health on an ubuntu server, after installing the browser it gives me —
405
Method Not Allowed
The method is not allowed for the requested URL.

I guess you try to access using the browser. in this case it means that the web client has not been correctly installed: see https://foss.heptapod.net/tryton/tryton/-/blob/branch/default/sao/README.md

installation according to these instructions - GNU Health/Installation - Wikibooks, open books for an open world
installed sao specified the path in the configuration file trytond.conf path
[web]
listen = localhost:8000
root = /home/gnuhealth/sao/package

I also receive
405
Method Not Allowed
The method is not allowed for the requested URL.

This guide does not seem to be complete as there is no references to nodejs nor bower.
Please follow the officiel steps from the README.

I can’t install gnuhealth-client 4.4.0…
stuck at this stage…
