Gulp is not converting scss to css

Question

In Visual Studio, Gulp is not running to convert my scss files to css.

The error I'm getting is:

cmd.exe /c gulp --tasks-simple C:\Users\sam\Documents\Visual Studio 2017\Projects\MyProject\MyProject\node_modules\node-sass\lib\binding.js:15 throw new Error(errors.missingBinary()); ^ Error: Missing binding C:\Users\sam\Documents\Visual Studio 2017\Projects\MyProject\MyProject\node_modules\node-sass\vendor\win32-x64-47\binding.node Node Sass could not find a binding for your current environment: Windows 64-bit with Node.js 5.x Found bindings for the following environments: - Windows 64-bit with Node.js 7.x This usually happens because your environment has changed since running npm install. Run npm rebuild node-sass to build the binding for your current environment.

I did run npm rebuild node-sass in the root of my project folder but still getting the same error. This is what I got after running npm rebuild node-sass:

Binary found at C:\Users\sam\Documents\Visual Studio 2017\Projects\MyProject\MyProject\node_modules\node-sass\vendor\win32-x64-51\binding.node Testing binary Binary is fine [email protected] C:\Users\sam\Documents\Visual Studio 2017\Projects\MyProject\MyProject\node_modules\node-sass

My Gulpfile.js looks like this:

var gulp = require('gulp'),
    sass = require("gulp-sass");;

gulp.task('default', function () {
    // place code for your default task here
});

gulp.task("sass", function () {
    return gulp.src('wwwroot/scss/style.scss')
      .pipe(sass())
      .pipe(gulp.dest('wwwroot/css'));
});

Any idea how I can fix this issue?

UPDATE: If I run node -v in command line, I get v7.10.0.

Also, I found this article and followed the instructions but the issue is still not resolved and I'm also now seeing an issue with Bower in my project. Here's the article: https://ryanhayes.net/synchronize-node-js-install-version-with-visual-studio-2015/

And here's the what I'm seeing in my project:

If I click "Manage Bower Packages" in Visual Studio, it just tries and tries but can't seem to find the installed packages.

UPDATE 2:

Here's the `package.json':

Answer 1

cnpm install gulp-load-plugins --save-dev

and then modify gulpfile

var gulp = require('gulp'),
    sass = require("gulp-sass"),
    gulpLoadPlugins = require('gulp-load-plugins'),
    $ = gulpLoadPlugins();

gulp.task('default', function () {
    // place code for your default task here
});

gulp.task("sass", function () {
    return gulp.src('wwwroot/scss/style.scss')
      .pipe($.sass())
      .pipe(gulp.dest('wwwroot/css'));
});
