Onsen theme customization: "yarn run serve" > "Command failed with signal "SIGABRT""

I am unable to open the theme customization as advised in the docs. I have installed the package dependencies, and everything is ok up until I run “yarn run serve” (or “npm run serve” / “yarn run build”).

I am running:

Yarn 1.16.0
OnsenUI 6.4.1

emccorson

This looks like a local setup problem. What version of Node and what version of Onsen UI are you using? The latest Onsen version is 2.10.8 so you can’t be using 6.4.1
