Gruntjs grunt发球挂起：重新加载任务

我正在开发一个由其他人构建的webapp…构建和运行的命令是

npm install
bower install
grunt serve

我以前使用过npm和bower，没有任何问题。在grunt到达“connect:livereload”任务之前，一切似乎都正常，而命令行刚刚挂起，没有错误消息

下面是package.json文件和grunt service-v的输出：

（详细）输出（从实时开始：重新加载）

以下是运行“grunt服务”后的（非详细）输出：

$ grunt serve
Running "serve" task

Running "clean:server" (clean) task
>> 1 path cleaned.

Running "jshint:all" (jshint) task

√ No problems


Running "jscs:src" (jscs) task
No code style errors found.
>> 21 files without code style errors.

Running "createDefaultTemplate" task

Running "handlebars:compile" (handlebars) task
>> 1 file created.

Running "clean:dist" (clean) task
>> 1 path cleaned.

Running "createDefaultTemplate" task

Running "handlebars:compile" (handlebars) task
>> 1 file created.

Running "less:dist" (less) task
>> 1 stylesheet created.

Running "copy:env" (copy) task
Copied 1 file

Running "copy:ol" (copy) task
Copied 2 files

Running "configureProxies" task
Proxy created for: /api to 52.20.39.250:80

Running "connect:livereload" (connect) task

这里是被卡住（在“运行”connect:livereload（连接）任务“）…没有光标或错误或任何进一步的输出。。。。 在这里，我希望看到“已启动连接web服务器”，并能够查看应用程序，但它挂起在这里，在我强制退出之前，没有进一步的输出或错误。该端口没有任何服务（我尝试在应用程序的grunt任务/config/connect文件中切换端口号作为测试，但没有更改）

这是Grunfile文件：

'use strict';

module.exports = function (grunt) {
    // show elapsed time at the end
    require('time-grunt')(grunt);
    // load all grunt tasks
    require('jit-grunt')(grunt, {
        useminPrepare: 'grunt-usemin',
        configureProxies: 'grunt-connect-proxy'
    });

    var yeomanConfig = {
        app: 'app',
        dist: 'dist'
    };

    grunt.initConfig({yeoman: yeomanConfig});

    //load all custom task configs
    grunt.loadTasks('grunt-tasks/config');
    grunt.loadTasks('grunt-tasks/register');

    grunt.registerTask('default', [
        'jshint',
        'jscs',
        //'test',
        'build'
    ]);

};

以下是grunt tasks/config中的“connect”文件：

    module.exports = function(grunt) {

    var SERVER_PORT = 9001;
    var LIVERELOAD_PORT = 35729;

    var lrSnippet = require('connect-livereload')({
        port: LIVERELOAD_PORT
    });

    var proxySnippet = require('grunt-connect-proxy/lib/utils').proxyRequest;

    var mountFolder = function (connect, dir) {
        return connect.static(require('path').resolve(dir));
    };

    // configurable paths
    var yeomanConfig = {
        app: 'app',
        dist: 'dist'
    };

    grunt.config('connect', {
        options: {
            port: grunt.option('port') || SERVER_PORT,
            hostname: '0.0.0.0'
        },
        proxies: [{
            context: ['/api'],
            host: 'HOST IP',
            port: 80
        }],
        livereload: {
            options: {
                middleware: function (connect) {
                    return [
                        proxySnippet,
                        lrSnippet,
                        mountFolder(connect, '.tmp'),
                        connect().use(
                          '/node_modules',
                          connect.static('./node_modules')
                        ),
                        mountFolder(connect, yeomanConfig.app)
                    ];
                }
            }
        },
        test: {
            options: {
                middleware: function (connect) {
                    return [
                        lrSnippet,
                        mountFolder(connect, '.tmp'),
                        mountFolder(connect, 'test'),
                        mountFolder(connect, yeomanConfig.app)
                    ];
                }
            }
        },
        testInBrowser: {
            options: {
                middleware: function (connect) {
                    return [
                        proxySnippet,
                        mountFolder(connect, '.tmp'),
                        mountFolder(connect, 'test'),
                        mountFolder(connect, yeomanConfig.app)
                    ];
                }
            }
        },
        dist: {
            options: {
                middleware: function (connect) {
                    return [
                        proxySnippet,
                        connect().use(
                          '/node_modules',
                          connect.static('./node_modules')
                        ),
                        mountFolder(connect, yeomanConfig.dist)
                    ];
                }
            }
        }
    });
}

有一件事我注意到了：当在webapp中

---

在这个项目的文件夹中，我的npm版本是2.14.20，但在我的用户文件夹中，npm版本是3.8.3（在两个目录中，我的节点版本是相同的，4.4.1）…这可能是这个问题的根源吗？我刚刚在webapp目录中运行了npm install npm-g，但从该目录查看时没有更改版本。

请发布您的Gruntfile@XavierPriour我在上面添加了Gruntfile和更多输出…谢谢，但我们还需要包含任务本身配置的文件（在grunt tasks/config和/register中）@XavierPriour ok，但这些目录中有几十个文件..我发布了我认为最相关的一个（grunt tasks/config/connect）上面。。。
