This can be fixed by removing yarn.lock and re-creating by running yarn, but this will probably pull latest versions of some dependencies which might break things.

For now, I can install dependencies with --ignore-engines, but is there any better way?

Thanks for looking into this.
re-creating the yarn.lock might not be a bad idea. it's been awhile.

I did re-create yarn.lock in local and looks like some remark dependencies are updated which breaks lint:md command with a warning.

I'm new to debugger.html project, yet to understand how things work here, so it would be nice if someone experienced actually fix development flow for node 10+.

Thanks :)

[jasonLaster]

thanks. will do

So, I'm working on #6730 and it is quite challenging. Haha turns out upgrading all the dependencies in one go has some surprises...
