JavaScript stack long-term stable branch development

Hey,

I needed to reproduce a bug on 2.4, not so old, branch and I am running into issue with npm install:

Downloading binary from https://github.com/sass/node-sass/releases/download/v4.7.2/linux-x64-83_binding.node
Cannot download "https://github.com/sass/node-sass/releases/download/v4.7.2/linux-x64-83_binding.node":

HTTP error 404 Not Found

I am unable to either install or update npm modules. I tried to delete npm_modules followed by either npm update, npm upgrade or npm install but everything leads to the same error.

Q1: How do I fix this?

Q2: If JS developers pull out release so early, how are we supposed to work with older branches? Rubygems are fine because once a gem is released is stays on the download site pretty much forever (or at least longer time).

Thanks

try deleting package-lock.json after removing node_modules/ and rerunning npm install perhaps?

Thanks npm install node-sass worked, as advised by Ron.
