我想使用this plunk在我的机器本地。但是，当我使用本地 Python 服务器或 http-server 运行它时，我不断收到以下错误:
Uncaught Error: [$injector:modulerr] Failed to instantiate module myApp due to:
Error: [$injector:nomod] Module 'myApp' is not available! You either misspelled the module name or forgot to load it. If registering a module ensure that you specify the dependencies as the second argument.
我的html 文件如下所示:

我不明白我做错了什么。我已经搜索过类似的错误消息，但没有找到任何可以帮助我解决问题的方法。
最佳答案
您在 angularjs 文件之前加载脚本文件，这就是您收到此错误的原因。 因此，在“angular.js”文件之后添加“main.js”文件。
<script src="http://ajax.googleapis.com/ajax/libs/angularjs/1.4.0/angular.js"></script>
<script scr="main.js"></script>
