node-sass/lib/extensions.js line 242:

leads to error 404.
May be this is the problem.

Please read the issue template. You have a version mismatch between node
sass and bide. Downgrade node or upgrade node sass.

i am trying to install [email protected] and while i checking in https://github.com/sass/node-sass/releases for supporting node version its saying this will support node 8. My node version is 8.2.1.. So this should work right?

OS | Architecture | Node
Windows | x86 & x64 | 0.10, 0.12, 1, 2, 3, 4, 5, 6, 7, 8
