Javascript '；反射能力'；未定义的角2

嘿，所以我刚开始用Angular 2使用webpack，我在尝试启动应用程序时遇到了这个错误

index.js:93未捕获类型错误：无法设置未定义的属性“reflectionCapabilities” 这是哪一行

我想这与我的网页构建/依赖性有关

这是我的网页配置文件，我用的是我正在看的一个教程

/// <binding BeforeBuild='Run - Development' />
// An attempt at a very simple webpack config file that shows
//  the minimum required to "compile" an angular app using
//  Sass (with view encapsulation), and external HTML templates
//
var autoprefixer = require("autoprefixer");

module.exports = {
    // Define the entry points for our application so webpack knows what to 
    //  use as inputs
    //
    entry: {
        app: ["./App/main"]
    },

    // Define where the resulting file should go
    //
    output: {
        filename: "content/[name].bundle.js"
    },

    // Define the extensions that we want webpack to resolve (we need to 
    //  override the default to ensure .ts files are included)
    //
    resolve: {
        extensions: ["", ".ts", ".js"]
    },

    // Turn on source maps for all applicable files.
    //
    devtool: "source-map",

    module: {
        loaders: [
            // Process any typescript or typescript-jsx files using the ts-loader
            //
            {
                test: /\.tsx?$/,
                loaders: ["ts-loader"]
            },

            // Process Sass files using the sass-loader first, and then with postcss,
            //  and finally with the raw-loader so we can convert the result into a 
            //  string and inject them into the 'styles' property of components (to 
            //  take advantage of view encapsulation)
            //
            {
                test: /\.scss$/,
                exclude: /node_modules/,
                loaders: ["raw-loader", "postcss-loader", "sass-loader"]
            },

            // Load any HTML files into raw strings so they can be included with
            //  the angular components in-line
            //
            {
                test: /\.html$/,
                loaders: ["html-loader"]
            }
        ]
    },

    // Configure postcss to run the autoprefixer plugin
    //
    postcss: function () {
        return [autoprefixer];
    }
}

关于我做错了什么有什么想法吗？

通过升级到rc.1到rc.2修复了这个问题，这给了我一个不同的错误：

未捕获异常：NgZone实例化期间出错！（ApplicationRef->ApplicationRef->NgZone）

---

然后我通过添加

import“zone.js”修复了这个问题

t main.ts的顶部，不是最好的解决方案，但看起来它现在可以工作了

我碰巧写了那个教程，在看到你的reddit评论后发现了这个问题。很抱歉你必须找到这个，但我很高兴你找到了，因为我学到了一些值得注意的东西：）

问题在于package.json中使用的角度版本。如果仔细观察，您会发现一些是在rc1版本上修复的，但其他（错误地）使用了允许他们安装rc2版本的
