Sadly, I encountered the same error after running yarn kbn clean...
I am going to try uninstalling Java, cleaning the cache, and then reinstalling to see where it is at then. The JScript compile/runtime errors seem to point to Java being the problem and, after removing the stray commas from the kibana/packages/kbn-babel-preset/node.js file again, the setup for eslint-import-resolver-kibana completes fine on a separate computer. Will comment with my update shortly after.
