npm - webpack导入firebase不起作用

Question

我在让 firebase 3.0.1 工作时遇到问题。我感觉这与我的 webpack 设置有关。我的文件在下面。使用 webpack 开发服务器运行我的应用程序时，出现错误:

Uncaught TypeError: firebase.initializeApp is not a function

有趣的是，如果我把 debugger;或 var firebase = require('firebase'); 之后的断点它似乎是一个空对象。

webpack.config.js

const webpack = require("webpack");

module.exports = {
    entry: './src/index.js',
    output: {
        path: 'public',
        filename: 'bundle.js'
    },
    module: {
        loaders: [{
            test: /\.js$/,
            exclude: /node_modules/,
            loader: 'babel-loader?presets[]=es2015&presets[]=react'
        }]
    },
    plugins: process.env.NODE_ENV === 'production' ? [
        new webpack.optimize.DedupePlugin(),
        new webpack.optimize.OccurrenceOrderPlugin(),
        new webpack.optimize.UglifyJsPlugin()
    ] : []
};

firebase.initializeApp(config);

我有 same problem ，不过有一个简单的解决方法:

var firebase = require('firebase/app');

这样你就得到了“真正的”firebase 模块。但是，您现在必须要求您需要的每个模块，以便正确加载，如下所示:

var firebase = require('firebase/app');
// all 3 are optional and you only need to require them at the start
require('firebase/auth');
require('firebase/database');
require('firebase/storage');

在我看来，当前的初始化代码有问题，看看它应该工作的源代码；但话又说回来，有点像你，我正在使用 browserify，并且没有在它之外进行测试，所以它可能是相关的。
