Had a lot of trouble installing the Node files; solved by rolling back to Node v14.x.x for the project. But getting lots of errors, including this one.

FWIW, lint:scss fails similarly.

Hello @seeze, Underscores seems to be a little bit outdated (I've opened an issue about it #1511). The problems you are facing are probably related to outdated libraries. I've updated the project libraries in a fork called Esqueleto that I've made for my own use. Fell free to use it if you think it may help you.

[seezee]

Fabio, thank you. I'll have a look at your fork.

Cheers @fabio-blanco - I've been thinking about forking this project to apply the various npm fixes too - thanks for doing it so I don't need to! :)

It is good to know it can be useful to more people. Now that I know that the Underscores project is no longer maintained, I will probably change the name of my fork and reorganize the sass sources to follow more atual recommendations from the actual versions of sass. A lot of things has changed and there is a lot of things outdated on the project.

I have updated the link to reflect to the master of the forked project and to the new name Esqueleto.
The project is basically the same with the updated dependencies but I've added a script to help one starting up with the starter theme usage and I've also made some improvements on the readme.
And I've also made some changes to the sass files to update it to the new dart sass way of doing things and to improve organization.

Hi, everyone ! I have just updated the npm packages (#1516), which seems to resolve the issues reported here.
