NgModule不是一个函数

问题描述：

截至去年2016年8月我开始运行时的JavaScript控制台错误：NgModule不是一个函数

错误：类型错误：s.NgModule不是一个函数（...）

在我RC4-基于应用。我还没有尝试更新到RC5，所以我期望我的基于RC4的代码在每个文档中仍然有效。我的package.json是（有点匿名）：

这意味着您的包之一已经升级，需要角2.看的RC5版在下列之一：

"ng2-bootstrap": "^1.0.24", 
"ng2-redux": "^3.3.0", 
"ng2-translate": "^2.1.0", 
"redux": "^3.5.2", 
"redux-thunk": "^2.1.0",

软件包编号前面的^表示至少该版本，但如果有更高版本可用，它将升级到该版本。要解决的方法是删除“^”，删除“node_modules”目录并再次执行“npm install”。

谢谢博彦 - 改为“ng2-translate”：“2.2.2”，修正了它:-) – nxn

太棒了！这很简单，我很开心！ –

纠正我，如果我错了。

我相信NgModule是RC5功能。您可能必须将角度2应用更新为RC5。

是的，我正在使用“ng2-translate”：“^ 2.1.0”，它引入了RC5依赖关系 - 更改为固定版本“2.2.2”只需要RC4并且现在解决了我的问题，但我需要升级适当的时候。 – nxn
