javascript - 使用gulp提供静态文件时出现TypeError

当请求Gulp提供静态内容并加载Web服务器时，出现以下错误。我正在关注专业的angularJS书。
package.json和gulpfile都位于同一文件夹中。

[21:30:44] Using gulpfile ~/Desktop/pro-angular2/gulpfile.js
[21:30:44] Starting 'connect'...
[21:30:44] 'connect' errored after 96 ms

以下是我的Gulp代码

var gulp = require('gulp');

var $ = require('gulp-load-plugins')();

gulp.task('default',[],function(){

});

gulp.task('connect', function() {
  var serveStatic = require('serve-static');
  var serveIndex = require('serve-index');
  var connect = require('connect');
  var app = connect()
    .use(require('connect-livereload')({
      port: 35729
    }))
    .use(connect.serveStatic('app'))
    .use(connect.serveIndex('app'));
  require('http').createServer(app)
    .listen(9000)
    .on('listening', function() {
      console.log('Started connect web server on http://localhost:9000');
    });
});

和我的package.json文件

{
  "name": "pro-angular2",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "author": "",
  "license": "ISC",
  "devDependencies": {
    "connect": "^3.4.0",
    "connect-livereload": "^0.5.4",
    "grunt": "^0.4.5",
    "grunt-contrib-connect": "^0.11.2",
    "grunt-contrib-jshint": "^0.11.3",

    "gulp": "^3.9.0",
    "gulp-jshint": "^2.0.0",

    "jshint": "^2.8.0",
    "load-grunt-tasks": "^3.3.0",
    "opn": "^3.0.3"
  }
}

最佳答案

server-static和serve-index不再是connect的一部分。它们被提取为单独的模块。您包含了这些单独的模块，因此只需使用：

.use(serveStatic('app'))
.use(serveIndex('app'));
