我正在尝试使用自动前缀,sass和livereload运行gulpfile。我花了一整个晚上,但我无法运行它们,到处都有它爆炸
有人可以提供安装了这些插件的教程或gulpfile吗?
非常感谢你:D
gulpfile.js
'use strict';
var gulp = require('gulp'),
sass = require('gulp-sass'),
livereload = require('gulp-livereload'),
autoprefixer = require('gulp-autoprefixer');
gulp.task('sass', function () {
gulp.src('public_html/style/scss/**/*.scss')
.pipe(sass().on('error', sass.logError))
.pipe(autoprefixer({
browsers: ['last 2 versions'],
cascade: false
}))
.pipe(gulp.dest('css'))
.pipe(livereload());
});
gulp.task('watch', function () {
livereload.listen(35729);
gulp.watch('public_html/style/scss/**/*.scss', ['sass']);
});

最佳答案
我以前有这个错误。
将以下内容添加到您的package.json
"es6-promise": "~3.1.2",
"es6-promise-polyfill": "~1.2.0",
然后在您的
gulpfile.js
中执行:var Promise = require('es6-promise').Promise;
应该有所帮助
