as stated in the issue link:
temporal solution:
npm install https://github.com/floatdrop/require-from-string/tarball/v1.1.0 --save
npm install
UPDATE:
It appears they are working on it. The require-from-string page used to return a 404, but at least now it loads the correct page on NPM’s website: https://www.npmjs.com/package/require-from-string
Still doesn’t appear to be working through npm install
yet.
UPDATE 2:
An official response from NPM: https://status.npmjs.org/incidents/41zfb8qpvrdj
UPDATE 3: issue seems to be resolved.
