我正在尝试在非常基本的AngularJs网络应用程序中注入依赖项，

var app = angular.module('app', ['ui-router']);

app.config(['$stateProvider','$controllerProvider', ($stateProvider, $controllerProvider) => {
  
  $controllerProvider.allowGlobals();
    $stateProvider.state('firstMessage', {
        url: '/first-msg',
        template: '<strong>hi this is irst msg</strong>'
    });
}]);

</head>

<body ng-app="app">
    <a href="#/first-msg">first</a>
    <div ui-view></div>
</body>

</html>

但是我遇到了这个错误-感谢您的帮助。

ui路由器的模块名称为'ui.router'，而不是'ui-router'。

尝试将您的代码更改为：

var app = angular.module('app', ['ui.router']);

如果使用库的未缩小版本，则会得到更好的错误消息。

使用：

https://cdnjs.cloudflare.com/ajax/libs/angular.js/1.7.5/angular.js
https://cdnjs.cloudflare.com/ajax/libs/angular-ui-router/1.0.21 /angular-ui-router.js

然后您的错误消息将是：

  

未捕获的错误：[$ injector：modulerr]由于以下原因而无法实例化模块应用程序：

     

错误：[$ injector：modulerr]由于以下原因而无法实例化模块ui路由器：

     

错误：[$ injector：nomod] 模块“ ui-router”不可用！您可能拼错了模块名称，或者忘记了加载它。如果注册模块，请确保将依赖项指定为第二个参数。

错误变得很明显，请使用ui.router而不是ui-router。

 var app = angular.module('app', ['ui.router']);
