SyntaxError: Block-scoped declarations (let, const, function, class) not yet supported outside strict mode

Getting the below error when updating to 4.0.1, which required Node.js 6.0.0

Failed to run "Gulpfile.js"...
cmd.exe /c gulp --tasks-simple
\node_modules\gulp-sass\index.js:66

I understand that you’ve dropped the 'use strict'; decleration, but is it really worth it considering this will force people to update Node.js for the sake of a few characters? (updating Node.js is a bit of a pita in some IDE’s such as VIsual Studio). I’ve not come across any other package that has taken his approach.

Installed node 6, and set IDE to use the system install and all works now, so thanks for update

As I said, node 6 should work. Your editor it probably configured to use VS’ embedded node version.

Yeah, if only Node v8.11.1 would play nicely.

I’ll probably revert to the standard Node/NPM versions in VS2017 and go back to 3.1.0 on this package.
