[英]Why is gulp browser-sync displaying a blank page on load?
我试图使用浏览器同步来建立一个gulp项目,并且一切正常,除了运行默认任务时,它最初在浏览器中显示空白页面。 如果我在浏览器中单击“刷新”或对css / js / html文件进行了任何编辑,则浏览器将重新加载并正确显示所有内容。
谁能告诉我我想念的东西吗?
var gulp = require('gulp');
var sass = require('gulp-sass');

var concat = require('gulp-concat');
var rename = require('gulp-rename');
gulp.task('sass', function() {
return gulp.src('app/scss/**/*.scss') // Gets all files ending with .scss in app/scss
.pipe(concat('styles.scss'))
.pipe(sass())
.pipe(cssnano())
.pipe(rename('styles.min.css'))
.pipe(gulp.dest('dist/css'))
.pipe(browserSync.reload({

我可以解决这个问题。 只需编辑您的主机文件(/ etc / hosts)并添加新的域引用即可。 121.0.0.1 myvirualdomain.localhost,其中myvirtualdomain.localhost是您尝试将浏览器同步代码指向的代理。
