Recommended Angular version (date = 19-06-2023)

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

Hello,
I was wondering if this is still the case? Where would I go to check which versions of angular are supported?

delete your modules folder and reinstall with npm install

I have tried the way deleting modules folder before, but it still doesn’t work,same error report. Thanks for the suggestion anyway.

I share my final solution here:npm config set legacy-peer-deps true
