Instalation failed with NPM error

[smurpins]

I'm currently using a fresh installation of Ubuntu 22.04.3 LTS
PHP already downgrade to 8.1.27
Using composer 2.6.6 (already try downgrade to version 1, as seen on tutorial page, but installation didn't work. So I keep this 2.6.6).

Below is error that appear when running composer:

Installing NPM dependencies for oat-sa/extension-tao-test

How to fix this?
Thanks.

Same issue here!

I've addressed this by installing nvm (https://github.com/nvm-sh/nvm) to manage multiple node versions. I then installed and used node 14 and the installation went through.

$ nvm install 14
$ nvm use 14
Now using node v14.18.0 (npm v6.14.15)
$ node -v
v14.18.0

I can't say if this the the best way to get the installation done it worked and the setup seems stable.
