gulp浏览器同步和重新加载问题

我是安装和使用gulp的新手，我花了好几天的时间才完成这一部分，然而，我从我的尝试和错误中学到了很多东西，但现在我遇到了一堵砖墙。
这就是我的gulpfile.js中的内容：

// MODULES
var gulp = require('gulp');
var sass = require('gulp-sass');
var js = require('gulp-uglify');
var imagemin = require('gulp-imagemin');
var browsersync = require('browser-sync');
var reload = browsersync.reload;
var plumber = require('gulp-plumber');
var gutil = require('gulp-util');
var autoprefixer = require('gulp-autoprefixer');
var sourcemaps = require('gulp-sourcemaps');
var rename = require('gulp-rename');
var concat = require('gulp-concat');



// ERROR LOG
var onError = function (err) {
    console.log('An error occurred:', gutil.colors.magenta(err.message));
    gutil.beep();
    this.emit('end');
};


// COMPILE AND MINIFY SASS
gulp.task('sass', function () {
    return gulp.src('./wp-content/themes/pixelboutique/sass/**/*.scss')
    .pipe(plumber())
    .pipe(sass.sync().on('error', sass.logError))
    .pipe(sourcemaps.write())
    .pipe(gulp.dest('./wp-content/themes/pixelboutique/css'))
    .pipe(browsersync.stream())
    done();
});


// MINIFY JS
gulp.task('js', function () {
    return gulp.src('./wp-content/themes/pixelboutique/js/*.js')
    .pipe(js())
    .on('error', onError)
    .pipe(rename({
        suffix: '.min'
    }))
    .pipe(concat('all.min.js'))
    .pipe(gulp.dest('./wp-content/themes/pixelboutique/js/min'))
    .pipe(browsersync.stream())
    done();
});


// IMAGES
gulp.task('imagemin', function () {
    return gulp.src('./wp-content/themes/pixelboutique/images/*')
    .pipe(imagemin())
    .pipe(gulp.dest('./wp-content/themes/pixelboutique/images'))
    done();
});


// BROWSERSYNC
gulp.task('browser-sync', function(done) {
    browsersync.init({
        proxy: 'http://localhost/testingsite/'
    })
    done();
});

// RELOAD
gulp.task('reload', function (done) {
    browsersync.reload();
    done();
});


// WATCH
gulp.task('watch', function() {
    gulp.watch('./wp-content/themes/pixelboutique/sass/**/*.scss', gulp.series('sass', 'reload'));
    gulp.watch('./wp-content/themes/pixelboutique/js/*.js', gulp.series('js', 'reload'));
    gulp.watch('./wp-content/themes/pixelboutique/images/*', gulp.series('imagemin', 'reload'));

    gulp.watch('./wp-content/themes/pixelboutique/**/*.php').on('change', browsersync.reload);
    gulp.watch('*/pixelboutique/**/*.php').on('change', browsersync.reload);
});


gulp.task('default', gulp.series('sass', 'js', 'imagemin', 'browser-sync', 'watch'));

// MODULES
var gulp = require('gulp');
var sass = require('gulp-sass');
var js = require('gulp-uglify');
var imagemin = require('gulp-imagemin');
var browsersync = require('browser-sync');
var reload = browsersync.reload;
var plumber = require('gulp-plumber');
var gutil = require('gulp-util');
var autoprefixer = require('gulp-autoprefixer');
var sourcemaps = require('gulp-sourcemaps');
var rename = require('gulp-rename');
var concat = require('gulp-concat');


// ERROR LOG
var onError = function (err) {
    console.log('An error occurred:', gutil.colors.magenta(err.message));
    gutil.beep();
    this.emit('end');
};

// COMPILE AND MINIFY SASS
gulp.task('sass', function () {
    return gulp.src('./wp-content/themes/pixelboutique/sass/**/*.scss')
    .pipe(plumber())
    .pipe(sass.sync().on('error', sass.logError))
    .pipe(sourcemaps.write())
    .pipe(gulp.dest('./wp-content/themes/pixelboutique/css'))
    // .pipe(browsersync.stream())
    done();
});

// MINIFY JS
gulp.task('js', function () {
    return gulp.src('./wp-content/themes/pixelboutique/js/*.js')
    .pipe(js())
    .on('error', onError)
    .pipe(rename({
        suffix: '.min'
    }))
    .pipe(concat('all.min.js'))
    .pipe(gulp.dest('./wp-content/themes/pixelboutique/js/min'))
    // .pipe(browsersync.stream())
    done();
});

// IMAGES
gulp.task('imagemin', function () {
    return gulp.src('./wp-content/themes/pixelboutique/images/*')
    .pipe(imagemin())
    .pipe(gulp.dest('./wp-content/themes/pixelboutique/images'))
    done();
});

// BROWSERSYNC
gulp.task('browser-sync', function(done) {
    browsersync.init({
        proxy: 'http://localhost/testingsite/'
    })
    done();
});

// RELOAD
gulp.task('reload', function (done) {
    browsersync.reload()
    done();
});

// WATCH
gulp.task('watch', function() {
    gulp.watch('./wp-content/themes/pixelboutique/sass/**/*.scss', gulp.series('sass', 'reload'));
    gulp.watch('./wp-content/themes/pixelboutique/js/*.js', gulp.series('js', 'reload'));
    gulp.watch('./wp-content/themes/pixelboutique/images/*', gulp.series('imagemin', 'reload'));

    gulp.watch('./wp-content/themes/pixelboutique/**/*.php').on('change', browsersync.reload);
    gulp.watch('*/pixelboutique/**/*.php').on('change', browsersync.reload);
});

gulp.task('default', gulp.series('sass', 'js', 'imagemin', 'browser-sync', 'watch'));

这是终端的输出：

我在sass，js和php中的文件更改会被监视，浏览器会刷新，但js和sass不会注入到网站中。php的变化是重新加载和注入好.
