Question

我的配置会执行它应该执行的所有操作，但它永远不会刷新浏览器。一旦我手动刷新它，就会有变化。我正在连接到默认的localhost：3000。任何想法为什么会这样或如何调试它？

gulpfile.js：

var gulp = require('gulp');
var sass = require('gulp-sass');
var sourcemaps = require('gulp-sourcemaps');
var browserSync = require('browser-sync');

gulp.task('html', function () {
    browserSync.reload();
});

gulp.task('sass', function() {
  return gulp.src('./app/scss/style.scss')
    .pipe(sass())
    .pipe(gulp.dest('./app/css'))
    .pipe(browserSync.reload({ stream:true }));
});

gulp.task('serve', function() {
  browserSync({
    server: {
      baseDir: 'app'
    }
  });
});

gulp.task('default', ['serve'], function () {
    gulp.watch('./app/scss/*.scss', ['sass', browserSync.reload]);
    gulp.watch('./app/*.html', ['html', browserSync.reload]);

});

控制台输出示例：

[BS] Local URL: http://localhost:3000
[BS] External URL: http://192.168.1.3:3000
[BS] Serving files from: app

Answer 1

我明白了：浏览器同步并不像隐式html标签，所以这（虽然有效的HTML5）不起作用：

<!doctype html>
<title>implicit</title>

但这会：

<!doctype html>
<html>
    <head>  
        <title>full doc</title>
    </head>
    <body></body>
</html>

浏览器同步（在gulp下）不刷新浏览器
