Javascript TypeError:element.summernote不是函数

我正在做一个基于Angular、Webpack等的项目，当我想使用它时，我遇到了一个非常有趣的问题

它不工作，并给我一个错误“TypeError:element.summernote不是函数”。如果将库添加为脚本标记，而不使用任何构建工具，则它可以正常工作，但使用Webpack则不能正常工作

那么，让我们看看文件和配置

webpack.config.js

let webpack = require('webpack');
let path = require('path');

module.exports = {

    entry: {
        bundle: [
            './app/app.js'
        ]
    },
    output: {
        path: path.join(__dirname, './public'),
        filename: '[name].js',
    },
    resolve: {
        root: __dirname,
        extensions: ['', '.js'],
        modulesDirectories: [
            'node_modules',
            'app'
        ],
    },
    externals: {

    },
    plugins: [
        new webpack.ProvidePlugin({
            $: 'jquery',
            jQuery: 'jquery'
        })
    ],
    module: {
        loaders: [
            {
                loader: 'babel-loader',
                query: {
                    presets: ['es2015']
                },
                test: /\.js$/,

我找到了，但它仍处于打开状态

我做了一些调试，检查了“summernote”指令的“link”方法，并将“element”记录到控制台，它的proto对象不包含任何jquery方法，包括“summernote”方法为什么？如何使其工作？

似乎jquery是按需使用的，没有在其他脚本之前加载，因此它不公开全局变量jquery，也不向元素附加适当的方法

下面的配置解决了这个问题

webpack.config.js

let webpack = require('webpack');
let path = require('path');

module.exports = {

    entry: {
        bundle: [
            './app/app.js'
        ]
    },
    output: {
        path: path.join(__dirname, './public'),
        filename: '[name].js',
    },
    resolve: {
        root: __dirname,
        extensions: ['', '.js'],
        modulesDirectories: [
            'node_modules',
            'app'
        ],
    },
    externals: {

    },
    plugins: [
        new webpack.ProvidePlugin({
            $: 'jquery',
            jQuery: 'jquery'
        })
    ],
    module: {
        loaders: [
            {
                loader: 'babel-loader',
                query: {
                    presets: ['es2015']
                },
                test: /\.js$/,

};

// Load libs

.config(function($routeProvider) {

    // Router
    $routeProvider

        .when('/', {
            template: '<summernote></summernote>'
        });
});

let webpack = require('webpack');
let path = require('path');

module.exports = {

            'script!jquery/dist/jquery.min.js',

            './app/app.js'
        ]
    },
    output: {
        path: path.join(__dirname, './public'),
        filename: '[name].js',
    },
    resolve: {
        root: __dirname,
        extensions: ['', '.js'],
        modulesDirectories: [
            'node_modules',
            'app'
        ],
    },
    externals: {
        // This mean that require('jquery') will refer to global var jQuery
        'jquery': 'jQuery' 
    },
    plugins: [

        // And replace it with require('jquery')
        new webpack.ProvidePlugin({
            $: 'jquery',
            jQuery: 'jquery'
        })
    ],
    module: {
        loaders: [
            {
                loader: 'babel-loader',
                query: {
                    presets: ['es2015']
                },
                test: /\.js$/,
                exclude: /(node_modules|bower_components)/
            }
        ]
    }

};

希望这将有助于澄清网页如何工作。如果我遗漏了什么，请分享您的想法和意见。

谢谢。通过添加名为“webpack.config.js”的新文件并将上述代码粘贴到/src文件夹中，我也遇到了同样的问题，但无法解决。有人能帮我吗？
