I have been struggling for a while now and it is fairly frustrating to be honest.
The problem:
I created a gulpfile for my static website, and all i want to do is use browserSync, to compile sass into css and to minify the script and css files. Everything works fine, excluding one thing:
When I run "gulp" everything loads, besides de css file, which is located in "CSS/". Apparently the server thinks that the css file is ("CSS/style.css/") a folder actually.
Screenshot with the console error:

the css file is located in "css/style.css"
"use strict";
let paths = {
script: "js/*.js",
minifiedScript: 'script.min.js',
cssPath: "css/*.css",
productionFolder: "production",
sassPath: "scss/*.scss",
htmlFiles: "*.html"
};
const gulp = require('gulp');
const concat = require('gulp-concat');
const uglify = require('gulp-uglify');
const sourcemaps = require('gulp-sourcemaps');
const del = require('del');
const browserSync = require('browser-sync').create();

const rename = require("gulp-rename");
gulp.task('browserSync', function() {
browserSync.init({

}
});
});
gulp.task('sass', function () {
return gulp.src(paths.sassPath)
.pipe(sass().on('error', sass.logError))
.pipe(gulp.dest('./css'))
.pipe(browserSync.stream());
});
gulp.task('index', function () {
var target = gulp.src('index.html');
// It's not necessary to read the files (will speed up things), we're only after their paths:
var sources = gulp.src([paths.script,paths.cssPath], {read: false});
return target.pipe(inject(sources))
.pipe(gulp.dest(''));
});
gulp.task('cssMinify', function(){
return gulp.src(paths.cssPath)
.pipe(cssMin())
.pipe(gulp.dest(paths.productionFolder + "/minified css"))
.pipe(browserSync.stream());
});

// You can use multiple globbing patterns as you would with `gulp.src`
return del(['build']);
});
gulp.task('scripts', ['clean'], function() {
// Minify and copy the JS file

So I have the following basic project structure that I use throughout all my projects:
Where the src folder looks like this:
I use Pug(Jade), sass compiling and useref js compilation.
This is my Jade views structure:
And this is my Jade index file:
This is my Jade scripts file, that is included in the index:
This is my pre-build index file, which is constructed by the index.pug:
And this is the build version of the index file:
My Gulpfile looks like this:

When I run the build task gulp build, all is well, except the relative/absolute paths inside the outputted CSS files, and the JS that runs the final product, whereas fonts/backgrounds/icons and JS functionality is not translated into the final build.
What is wrong with my Gulp file, and how can I fix it?
Here is the snapshot of command prompt when I run gulp. Previously it used to work correctly but now, it is showing some weird errors.
my view folder is supposed to contain only templates, so why is it displaying bootstrap.social.css not found?
and my project folder looks like-

controllers.js
services.js

sass task first runs to create 2 css files into builds/css/
After that css task runs and should concat all css files from the config.paths.css but it doesn't, only watch task does and barely, sometimes it does, sometimes it doesn't (seriously). I feel there is some spaghetti going on here.
If you are expecting that the sass task will always finish before the css task starts Don't. From the gulp documentation
Note: The tasks will run in parallel (all at once), so don't assume that the tasks will start/finish in order.
The usual way to fix this is to make the css task wait for the sass task to finish by:
gulp.task('css', ['sass'], function() {
This is a project I brought from the internet, I think this used laravel framework and compressed using Gulp. It's working fine. But I need to modify js files in it.

So I am trying to set up the livereload server, however, I never get the message Live reload server listening on: <port_number> like in this video. If I change my files, the console says that the file was reloaded. I have the Chrome extension installed. What am I missing? Thanks.

I use browser-sync to reload the browser when a file has changed.
Try something like this:
var gulp = require('gulp');
var browserSync = require('browser-sync').create();
gulp.task('serve', function() {
gulp.watch("app/**/*.js").on('change', browserSync.reload);
gulp.watch("templates/**/*.html").on('change', browserSync.reload);
gulp.watch("css/**/*.css").on('change', browserSync.reload);
browserSync.init({
server: "./"
});
});
gulp.task('default', ['serve']);
I recommend your attention to the real-time browser page reload tool.

Easy to use. Works independently of the IDE. But you need the IDE to be able to auto-save files. Also works with tools like Gulp, WebPack, Grunt and others.
