Angular error in MEAN stack - Uncaught Error: $injector:modulerr

Question

我正在做一个简单的 MEAN 堆栈，代码一开始就很好，当我多写几行代码时 Angular 显示错误。我做错了什么？对于这个问题，我无法跟随 Internet MEAN 堆栈课程。请帮助解决这个问题。

Html Code of index.

<html ng-app="myApp">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
<title>Contact list App</title>
    <link rel="stylesheet" href="css/metro-bootstrap.min.css" />
</head>
<body>
    <div class="container" ng-controller="AppCtrl">
        <section class="row">
            <div class="col-lg-12 text-center">
                <h1>This is a MEAN stack - Contact list!</h1>
                    <table class="table">
                        <thead>
                            <tr>
                                <th class="text-center">Name</th>
                                <th class="text-center">Email</th>
                                <th class="text-center">P. Number</th>
                            </tr>
                        </thead>
                        <tbody>
                            <tr ng-repeat="contact in contactist">
                                <td>{{contact.name}}</td>
                                <td>{{contact.email}}</td>
                                <td>{{contact.number}}</td>
                            </tr>
                        </tbody>
                    </table>
                </div>

</body>

Controller

var myApp = angular.module('myApp', ['ngRoute']);function AppCtrl($scope, $http) {
console.log("Hello world from controller.js");

$http.get('/contactlist').success(function (response) {
    console.log("I got the data");
    $scope.contactList = response;
});}

Server

var express = require('express');
var app = express();
app.use(express.static(__dirname + "/public"));

app.get('/contactList', function (req, res) {
    console.log("I got the request!");

    person1 = {
        name: 'Tim',
        email: 'tim@domain.com',
        number: '(111) 11-11-111'
    };
    person2 = {
        name: 'Rod',
        email: 'rod@domain.com',
        number: '(211) 11-11-111'
    };
    person3 = {
        name: 'Eddie',
        email: 'eddie@domain.com',
        number: '(311) 11-11-111'
    };

    res.json([person1, person2, person3]);
});

app.listen(3000);
console.log("Server running from port 3000");

This is the error: Uncaught Error: [$injector:modulerr] [AngularJs Error]1

看起来您的控制器似乎没有连接 - 您已经声明了该功能，但没有告诉 angular。试试这个：

var myApp = angular.module('myApp', ['ngRoute'])

myApp.controller('AppCtrl', function($scope, $http) {
    console.log("Hello world from controller.js");

    $http.get('/contactlist').success(function (response) {
      console.log("I got the data");
      $scope.contactList = response;
   });
});

我也没有看到脚本标签加载的迹象 angular，但它必须在那里才能获得错误消息。您是否还记得包括 ngRoute，例如？
