gulp + browser-sync Cannot GET / error
<p>I am learning the front-end build system currently gulp, i want to use brower-sync  and the problem is it is not throwing an error in the commad line but instead when it brings up the browser it will not display my html file and it will say  "Cannot GET /" error in the browser window. This is my gulpfile.js code</p>

<pre><code>var gulp = require('gulp'),
   uglify = require('gulp-uglify'),
   compass= require('gulp-compass'),
   plumber = require('gulp-plumber'),
   autoprefixer = require('gulp-autoprefixer'),
   browserSync = require('browser-sync'),
   reload = browserSync.reload,
   rename = require('gulp-rename');


gulp.task('scripts', function() {
   gulp.src(['public/src/js/**/*.js', '!public/src/js/**/*.min.js'])
      .pipe(plumber())
      .pipe(rename({suffix: '.min'}))
      .pipe(uglify())
      .pipe(gulp.dest('public/src/js/'));
});

gulp.task('styles', function() {
   gulp.src('public/src/scss/main.scss')
      .pipe(plumber())
      .pipe(compass({
          config_file: './config.rb',
          css: './public/src/css/',
          sass: './public/src/scss/'
      }))
     .pipe(autoprefixer('last 2 versions'))
     .pipe(gulp.dest('public/src/css/'))
     .pipe(reload({stream:true}));
});


gulp.task('html', function() {
  gulp.src('public/**/*.html');
});  

gulp.task('browser-sync', function() {
    browserSync({
      server: {
         baseDir: "./public/"
      }
   });
});

gulp.task('watch', function() {
   gulp.watch('public/src/js/**/*.js', ['scripts']);
   gulp.watch('public/src/scss/**/*.scss', ['styles']);
   gulp.watch('public/**/*.html', ['html']);
});

gulp.task('default', ['scripts', 'styles', 'html', 'browser-sync', 'watch']);
</code></pre>

<p>i am using windows and git bash and version is <code>"browser-sync": "^2.12.5"</code> so what is the problem and try to explain for me in order to get something out of it.</p>
