$injector:modulerr AngularJS，到目前为止已经尝试了所有内容

我是angular的新手，我正在angular js网站上学习教程

到目前为止我尝试了什么：

• 安装angular路由并在angular.min.js下注入脚本
• 在我的模块中使用了ngRoute
• 将控制器脚本添加到我的layout.jade中
• 使用了另一个视图引擎vash，仍然存在相同的错误
• 在头部、身体末端、布局视图、index.jade中包含脚本，没有任何作品

我两天来一直在努力解决这个错误。请帮帮我：（

这是我的代码：

layout.jade：

doctype html
html(ng-app="phoneCatApp")
  head
    meta(charset="utf-8")
    script(src='lib/angular/angular.min.js')
    script(src='lib/angular-route/angular-route.min.js')
    script(src='js/controllers.js')
    title= title
    link(rel='stylesheet', href='/stylesheets/style.css')
  body(ng-controller="PhoneListCtrl")
    block content

index.jade:

extends layout
block content
    ul
        li(ng-repeat="phone in phones")
            span {{phone.name}}
            p {{phone.snıppet}}

controller.js:

var phonecatApp = angular.module('phonecatApp', ['ngRoute']);
phonecatApp.controller('PhoneListCtrl', function ($scope) {
    $scope.phones = [
        {
            'name': 'Nexus S',
            'snippet': 'Fast just got faster with Nexus S.'
        },
        {
            'name': 'Motorola XOOM™ with Wi-Fi',
            'snippet': 'The Next, Next Generation tablet.'
        },
        {
            'name': 'MOTOROLA XOOM™',
            'snippet': 'The Next, Next Generation tablet.'
        }
    ];
});

index.js:

var express = require('express');
var router = express.Router();
/* GET home page. */
router.get('/', function (req, res) {
    res.render('index', { title: 'Express' });
});
module.exports = router;

app.js:

var express = require('express');
var path = require('path');
var favicon = require('serve-favicon');
var logger = require('morgan');
var cookieParser = require('cookie-parser');
var bodyParser = require('body-parser');
var routes = require('./routes/index');
var users = require('./routes/users');
var app = express();
// view engine setup
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'jade');
// uncomment after placing your favicon in /public
//app.use(favicon(__dirname + '/public/favicon.ico'));
app.use(logger('dev'));
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: false }));
app.use(cookieParser());
app.use(require('stylus').middleware(path.join(__dirname, 'public')));
app.use(express.static(path.join(__dirname, 'public')));
//app.use('/', routes);
//app.use('/users', users);
// catch 404 and forward to error handler
app.use(function (req, res, next) {
    var err = new Error('Not Found');
    err.status = 404;
    next(err);
});
// error handlers
// development error handler
// will print stacktrace
if (app.get('env') === 'development') {
    app.use(function (err, req, res, next) {
        res.status(err.status || 500);
        res.render('error', {
            message: err.message,
            error: err
        });
    });
}
// production error handler
// no stacktraces leaked to user
app.use(function (err, req, res, next) {
    res.status(err.status || 500);
    res.render('error', {
        message: err.message,
        error: {}
    });
});

module.exports = app;

编辑：

我发现了问题。当我在脚本的开头插入"/"时，问题就解决了。这是因为路径应该是绝对的，以便从子目录中找到脚本。谢谢大家。
