Angular 在scss保存时重新加载页面

我正在使用官方指南玩Angular 2

package.json文件中的开发人员依赖项允许通过保存html文件进行实时重新加载

我还使用Gulp和live将SCS重新加载到css来装饰我的东西

我想要的是绑定Gulp的scss实时重载和Angular 2的html实时重载。我的意思是，当我在SCS或html文件中保存更改时，我希望这些更改通过实时重新加载完成

目前，我只能通过在终端中运行Gulp命令或npmstart命令来分别更改scss和html

我的gulpfile.js代码：

var gulp = require('gulp');
var sass = require('gulp-sass');

gulp.task('sass', function(){
      return gulp.src('app/assets/scss/styles.scss')
   .pipe(sass())
   .pipe(gulp.dest('app/assets/css'))
});

My package.json代码：

{
 "name": "app",
 "version": "1.0.0",
 "scripts": {
    "start": "concurrently \"npm run tsc:w\" \"npm run lite\" ",
    "lite": "lite-server",
    "postinstall": "typings install",
    "tsc": "tsc",
    "tsc:w": "tsc -w",
    "typings": "typings"
 },

首先，你必须告诉你的孩子注意你的

scss

文件中的变化

在yougulpfile.js中

//Watch task
gulp.task('sassWatch',function() {
    gulp.watch('app/assets/scss/**/*.scss',['sass']);
});

其次，您必须同时启动tsc watch和lite服务器的gulp watch

在您的package.json中

"scripts": {
    "start": "concurrently \"npm run sass:w\" \"npm run tsc:w\" \"npm run lite\" ",
    "lite": "lite-server",

    "postinstall": "typings install",

    "tsc": "tsc",
    "tsc:w": "tsc -w",

    "sass": "gulp sass",
    "sass:w": "gulp sassWatch", 

    "typings": "typings"
 },

是的，但事实上它并没有改变任何事情。它允许在TerminalMabe lite服务器中使用npm start命令，使用Gulp或html（ts/js…）更改scss文件。默认情况下，服务器不会在css文件中查找更改。您是否尝试自定义lite服务器配置？本教程介绍如何将SCS编译为css，甚至进行实时重新加载：
