Cannot unpack with npm run dev

For a couple of days I have been trying to unpack Tailwind from Webmix following the steps detailed in the info, but something always goes wrong. Down here I am pasting the error log.

I should mention that npm version is currently 6.9.0 I have tried to clear cache, delete node_modules foilder and then reinstall npm install; nothing has worked so far, so I resolved to open a thread here.

    ^
