Question

我开始将我的角度应用程序迁移到webpack。我有一个文件结构如下：

- app/
------ app.js
------ index.html
- lib/
----- angular.js
----- jquery.js
----- ...
- webpack.config.js

由于限制，我无法使用npm来安装库。我的所有库文件都位于lib和其他文件夹中。我的webpack配置如下所示：

var webpack = require('webpack'),
    path = require('path');

module.exports = {
    context: __dirname,
    entry: {
        app: [ './app/app.js'],
        vendors: ['angular']
    },
    output: {
        path: __dirname + '/build',
        filename: 'bundle.js'
    },
    resolve: {
        alias: {
            angular: __dirname + "/lib/angular"
        }
    },
    debug: false,
    devtool: 'source-map',
    module: {
        loaders: [
            {
                test: /\.js$/,
                exclude: /(node_modules|bower_components)/,
                loader: 'babel-loader',
                query: {
                    presets: ['es2015']
                }
            },
            {
                test: /\.css$/,
                loader: "style-loader!css-loader"},
            {
                test: /\.png$/,
                loader: "url-loader?limit=100000"},
            {
                test: /\.jpg$/,
                loader: "file-loader"
            },
            {
                test: /\.json/,
                loader: 'json'
            }
        ]
    },
    plugins: [
        new webpack.ProvidePlugin({
            angular: "angular"
        }),
        new webpack.optimize.OccurenceOrderPlugin(),
        new webpack.optimize.DedupePlugin(),
        new webpack.optimize.CommonsChunkPlugin('vendor', 'vendor.js', Infinity)
    ]
}

我收到错误

angular.js?848f:80Uncaught 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.

app.js如下所示

angular.module("myApp", [])
.controller("myCtrl", function(){ ... });

感谢您的帮助！

首先，在您的条目中修复拼写错误vendor而不是vendors。它应与 CommonsChunkPlugin

中的名称匹配

entry: {
    app: [ './app/app.js'],
    vendor: ['angular']
},

其次，删除 ProvidePlugin

plugins: [
        new webpack.optimize.OccurenceOrderPlugin(),
        new webpack.optimize.DedupePlugin(),
        new webpack.optimize.CommonsChunkPlugin('vendor', 'vendor.js', Infinity)
    ]

现在它应该有效。

但实际上，我不知道用webpack加载外部库是否正确。（Webpack对我来说是超级黑盒子，gulp更容易预测）。所以现在它有效，但没有适当的DI。

从webpack中没有npm的外部lib文件夹加载库
