Hello internet-wanderer,
You most likely found this topic as you are stuck with installing openEMS UI…
The manual specifies installing angular by npm install -g @angular/cli However this installs automatically Angular 16. Currently this is not supported (see pull request 2183)
The angular version you should use is 15.1.2 the install command is thus
npm install -g @angular/cli@15.1.2
Hopefully i saved you a couple of hours figuring this out. However, if you read this in the future, please check if angular X is then supported, before doing the latest install.
Kind Regards,
Menno Spitteler
