Question

所以我已经完成了以下工作，似乎解决了很多使jQuery和Laravel Mix（4.0）绊倒的问题：

.autoload({
    'jquery': ['$', 'window.jQuery', 'jQuery'],
    'clipboard': ['ClipboardJS'],
    'popper.js':  ['Popper']
});

这使我不再遇到$ is not defined错误。

但是现在，如果我管理日志$或jQuery或window.jQuery，则不再是is not defined而是undefined。

我该如何解决？变量已正确附加到窗口，但它们为空...

我认为我加载模块错误，或者对package.json和webpack.mix.js的交互方式感到困惑。每个文件的完整文件如下：

package.json：

{
    "private": true,
    "scripts": {
        "dev": "npm run development",
        "development": "cross-env NODE_ENV=development node_modules/webpack/bin/webpack.js --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js",
        "watch": "npm run development -- --watch",
        "watch-poll": "npm run watch -- --watch-poll",
        "hot": "cross-env NODE_ENV=development node_modules/webpack-dev-server/bin/webpack-dev-server.js --inline --hot --config=node_modules/laravel-mix/setup/webpack.config.js",
        "prod": "npm run production",
        "production": "cross-env NODE_ENV=production node_modules/webpack/bin/webpack.js --no-progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js"
    },
    "devDependencies": {},
    "dependencies": {
        "@fortawesome/fontawesome-free": "^5.6.3",
        "bootstrap": "^4.2.1",
        "bootstrap-datepicker": "^1.8.0",
        "clipboard": "^2.0.4",
        "inputmask": "^4.0.6",
        "jquery": "^3.2",
        "jquery-editable-select": "^2.2.5",
        "jquery-lazy": "^1.7.10",
        "laravel-mix": "4.0",
        "popper.js": "^1.12.9"
    }
}

webpack.mix.js：

    mix
  .js([



    /*
    |--------------------------------------------------------------------------
    | Modules
    |--------------------------------------------------------------------------
    */
    'node_modules/jquery/dist/jquery.min.js',
    'node_modules/popper.js/dist/umd/popper.min.js',
    'node_modules/bootstrap/dist/js/bootstrap.min.js',
    'node_modules/bootstrap-datepicker/dist/js/bootstrap-datepicker.min.js',
    'node_modules/jquery-lazy/jquery.lazy.min.js',
    'node_modules/jquery-lazy/jquery.lazy.plugins.js',
    'resources/modules/jRange/jquery.range-min.js',
    'node_modules/inputmask/dist/jquery.inputmask.bundle.js',
    'node_modules/clipboard/dist/clipboard.min.js',
    'resources/js/app.js'
  ], 'public/js/app.js')
  .autoload({
    'jquery': ['$', 'window.jQuery', 'jQuery'],
    'clipboard': ['ClipboardJS'],
    'popper.js': ['Popper']
  });

如果您有任何建议，请告诉我。我尝试使用npm run dev和npm run production并得到相同的错误undefined输出。

因此，使用开箱即用的混合方式来获取jQuery，我这样做：

let mix = require('laravel-mix');

/*
 |--------------------------------------------------------------------------
 | Mix Asset Management
 |--------------------------------------------------------------------------
 |
 | Mix provides a clean, fluent API for defining some Webpack build steps
 | for your Laravel application. By default, we are compiling the Sass
 | file for the application as well as bundling up all the JS files.
 |
 */

mix.js('resources/assets/js/app.js', 'public/js')
   .sass('resources/assets/sass/app.scss', 'public/css')
   .version();

然后在resources / assets / js / bootstrap.js中：

try {
    window.$ = window.jQuery = require('jquery');

    require('bootstrap');
} catch (e) {}

Webpack可以做其他所有事情。

是的，npm正在安装jQuery，这是我的package.json：

{
    "private": true,
    "scripts": {
        "dev": "npm run development",
        "development": "cross-env NODE_ENV=development node_modules/webpack/bin/webpack.js --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js",
        "watch": "cross-env NODE_ENV=development node_modules/webpack/bin/webpack.js --watch --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js",
        "watch-poll": "npm run watch -- --watch-poll",
        "hot": "cross-env NODE_ENV=development node_modules/webpack-dev-server/bin/webpack-dev-server.js --inline --hot --config=node_modules/laravel-mix/setup/webpack.config.js",
        "prod": "npm run production",
        "production": "cross-env NODE_ENV=production node_modules/webpack/bin/webpack.js --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js"
    },
    "devDependencies": {
        "axios": "^0.16.2",
        "bootstrap": "^4.1",
        "cross-env": "^5.1.4",
        "jquery": "^3.3.1",
        "laravel-mix": "^1.7.2",
        "lodash": "^4.17.5",
        "vue": "^2.5.16"
    },
    "dependencies": {
        "@fortawesome/fontawesome": "^1.1.5",
        "@fortawesome/fontawesome-free-webfonts": "^1.0.9",
        "ar.js": "^1.4.10",
        "chess.js": "^0.10.2",
        "chessboardjs": "0.0.1",
        "font-awesome": "^4.7.0",
        "laravel-echo": "^1.4.0",
        "popper.js": "^1.14.3",
        "socket.io-client": "^2.1.1",
        "typeface-raleway": "0.0.54"
    }
}

Laravel Mix和NPM jQuery已自动加载但未定义
