Question

我正在尝试使用浏览器同步建立一个gulp项目，一切正常，但是当我运行我的默认任务时，它最初在浏览器中显示一个空白页面。如果我在浏览器中点击刷新或对css / js / html文件进行任何编辑，浏览器会重新加载并正确显示所有内容。

有谁能告诉我我错过了什么？

    .pipe(concat('styles.scss'))
    .pipe(sass())
    .pipe(cssnano())
    .pipe(rename('styles.min.css'))
    .pipe(gulp.dest('dist/css'))
    .pipe(browserSync.reload({
      stream: true
    }))
    .pipe( notify({ message: "sass tasks have been completed!"}) );
});

// Concatenate & Minify JS
gulp.task('scripts', function() {
    return gulp.src('app/js/**/*.js')
        .pipe(concat('js/main.js'))
        .pipe(gulp.dest('dist'))
        .pipe(rename('main.min.js'))
        .pipe(uglify())

});

gulp.task('browserSync', function() {
  browserSync.init({
    server: {

  .pipe(fileinclude())
    .pipe(useref())
    .pipe(gulp.dest('dist'))
    .pipe(browserSync.reload({

    }))
    .pipe( notify({ message: "fileInclude tasks have been completed!"}) );

gulp.task('watch', ['browserSync', 'sass', 'scripts', 'fileinclude'], function (){
  gulp.watch('app/scss/**/*.scss', ['sass']);
  gulp.watch('app/**/*.html', ['fileinclude']);
  gulp.watch('app/js/**/*.js', ['scripts']);
});

gulp.task('useref', function(){
  return gulp.src('app/*.html')
    .pipe(useref())
    .pipe(gulp.dest('dist'))
    .pipe( notify({ message: "useref tasks have been completed!"}) );
});

gulp.task('clean:dist', function() {
  return del.sync('dist/**/*');
})


gulp.task('default', function (callback) {
  runSequence(['clean:dist', 'sass', 'scripts', 'fileinclude', 'useref', 'browserSync', 'watch'],
    callback
  )
})

gulp.task('build', function (callback) {
  runSequence(
    'clean:dist',
    'sass',
    'scripts',
    'fileinclude',
    ['useref'],
    callback

我可以解决这个问题。只需编辑您的主机文件（/ etc / hosts）并添加新的域引用。 121.0.0.1 myvirualdomain.localhost 其中myvirtualdomain.localhost是您尝试指向您的browsersync代码的代理。

为什么gulp browser-sync在加载时显示空白页面？
