Gulp更新后不会重新加载HTML或CSS

Question

在hbs或css文件中更新后，Gulp不会重新加载页面，browserSync怎么了

这是gulpfile.js中的设置

"use strict";
var gulp = require('gulp'),
    babel = require("gulp-babel"),
    path = require('path'),
    sass = require('gulp-sass'),
    slang = require('gulp-slang'),
    handlebars = require('handlebars'),
    config = require('./gulp.config')(),
    gulpHandlebars = require('gulp-handlebars-html')(handlebars),
    regexRename = require('gulp-regex-rename'),
    replace = require('gulp-replace'),
    open = require('gulp-open'),
    browserSync = require('browser-sync').create(),
    baseURL = 'site-path/';

gulp.task('jstxt', function () {
    return gulp.src(baseURL + 'js.txt')
        .pipe(gulp.dest(baseURL));
});
gulp.task('csstxt', function () {
    return gulp.src(baseURL + 'css.txt')
        .pipe(gulp.dest(baseURL));
});
gulp.task('sass', function () {
    return gulp.src(baseURL + 'style.scss')
        .pipe(sass())
        .pipe(gulp.dest(baseURL))
        .pipe(browserSync.stream());
});
function reload(done) {
browserSync.reload();
done();
}
gulp.task('watch', function () {
    gulp.watch(baseURL + "scss/*.scss", ['sass']);
    gulp.watch(baseURL + 'js/*.js')
        .on('change', function (js) {
            if (js.path.length !== 0) {
                return gulp.src(js.path);
            } else {
                return;
            }
        });
    gulp.watch(baseURL + 'js.txt',['jstxt']);
    gulp.watch(baseURL + 'css.txt',['csstxt']);
});

gulp.task('default', ['watch'], gulp.parallel(reload));

/* Handlebar Setup for Frontend */
gulp.task('compileHtml', function () {
    var templateData = {
            multiply: function multiply(a, b) {
                return +a * +b;
            }
        },
        options = {
            partialsDirectory: [config.templatePartialPath]
        };
    return gulp.src(config.templatePath + "*.page.hbs")
        .pipe(gulpHandlebars(templateData, options))
        .pipe(regexRename(/\.page\.hbs$/, ".html"))
        .pipe(replace(/\uFEFF/ig, "")) //cut out zero width nbsp characters the compiler adds in
        .pipe(gulp.dest(config.templateOutputPath))
        .pipe(browserSync.stream());
});

gulp.task('compileHtml:watch', function () {
    return gulp.watch(config.templates, ['compileHtml'], gulp.parallel(reload));
});

// Open one file with default application
gulp.task('open', function () {
    gulp.src('templates/dist/index.html')
        .pipe(open());
});
