当我更改index.html文件时，我的网页没有更新

Question

我是使用gulp.js的初学者，我的网页不受我在index.html文件中所做的更改的影响

我看到了这个错误

    server.changed(e.path);
       ^
TypeError: undefined is not a function

我试着改变吞咽的肝脏，但我做不到。

我的gulpfile.js

​

var gulp = require('gulp'),
    gutil = require('gulp-util'),
    uglify = require('gulp-uglify'),
    concat = require('gulp-concat'),
    livereload = require('gulp-livereload'),
    lr = require('tiny-lr'),
    server = lr();

var jsSources = [
  'components/scripts/scriptOne.js',
  'components/scripts/scriptTwo.js'
];

gulp.task('js', function() {
  gulp.src(jsSources)
          .pipe(uglify())
          .pipe(concat('script.js'))
          .pipe(gulp.dest('js'));
});

gulp.task('watch', function() {
  var server = livereload();
  gulp.watch(jsSources, ['js']);
  gulp.watch(['js/script.js', '*.html'], function(e) {
    server.changed(e.path);
  });
});

gulp.task('default', ['js', 'watch']);

var gulp = require('gulp'),
    gutil = require('gulp-util'),
    uglify = require('gulp-uglify'),
    concat = require('gulp-concat'),
    livereload = require('gulp-livereload'),
    lr = require('tiny-lr'),
    server = lr();

var jsSources = [
  'components/scripts/scriptOne.js',
  'components/scripts/scriptTwo.js'
];

gulp.task('js', function() {
  gulp.src(jsSources)
          .pipe(uglify())
          .pipe(concat('script.js'))
          .pipe(gulp.dest('js'));
});

gulp.task('watch', function() {
  livereload.listen()
  var server = livereload();
  gulp.watch(jsSources, ['js']);
  gulp.watch(['js/script.js', '*.html'], function(e) {
    server.changed(e.path);
  });
});

gulp.task('default', ['js', 'watch']);

Gulp的插件(如LiveReload)经常更新，在这种情况下，会引起轻微的差异，影响Lynda.com的课程。他们在这里发布了更正：
