NgModule不是一个函数

Question

截至2016年8月19日上周五，我开始收到运行时javascript控制台错误：

错误: TypeError: s.NgModule不是函数(…)

在我的基于RC4的应用程序中。我还没有尝试更新到RC5，所以我希望我的基于RC4的代码仍然可以按照文档的要求工作。我的package.json是(有点匿名的)：

Answer 1

如果我错了，请纠正我。

我相信NgModule是RC5的特性。你可能不得不将你的angular 2应用更新到RC5。

Answer 2

这意味着您的某个包已经升级，需要Angular 2的RC5版本。请查看以下内容之一：

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

包号前面的^至少表示该版本，但如果有更高版本可用，则会升级到该版本。修复的方法是删除"^"，删除"node_modules“目录，然后再次执行"npm install”。
