Setup of local front-end does not work

[Sambam2]

I want to run the front-end (client-admin & client-kundenportal) locally to try out some changes to it. However, the setup following https://github.com/OpenOlitor/OpenOlitor/wiki/Doku-Technisch_Client_Ent-Setup does not work as expected. According to the .nvmrc file, Node v18.12.1 should be used, but so far I only got it working with Node v15.14.0 (npm v7.7.6). When using a higher version of node, running npm install leads to :

as well as a ton of warning. Is there another way to let the front-end run locally and separate from the other services?

Sorry for the (large) delay!

I don't understand exactly what your request is: You want to run it on a higher node version, right?

Since this is (still) a Angular 1 application using bower I don't think it's easy to use a higher node version.
