Though I can download https://github.com/sass/node-sass/releases/download/v4.9.0/linux-x64-48_binding.node from browser

Haven't digged in but from the output you pasted it looks like the install step for this package executes a script scripts/install.js which is doing some kind of fetching from the internet, which is disallowed during a nix build (assuming you have sandboxing enabled). This kind of thing is unfortunately pretty much only solvable by modifying the autogenerated definition of the package, adding a patch step to either modify or skip the install script.

@adnelson I think we can close this issue since it only reproducible in nix repl

I am having the same issue with nix-build on a nixos machine. Strangely it was working on a similar machine yesterday.
