Question

我在Symfony中用encore和yarn做脚本JS，当我不使用jquery并且从不要求他时，我的JS可以正常工作。但是目前，我使用const $ = require('jquery')添加了jquery，例如我的脚本不起作用，并且没有错误消息。

我尝试评论.enableSingleRuntimeChunk()，使用CDN添加jquery，然后尝试其他项目。没什么改变。

//base.html.twig
{% block javascripts %}
            <script src="{{ asset('build/runtime.js') }}"></script>
            <script src="{{ asset('build/app.js') }}" type="text/javascript"></script>
{% endblock %}

// Need jQuery? Install it with "yarn add jquery", then uncomment to require it.
const $ = require('jquery');

console.log('hello');

Encore
    // directory where compiled assets will be stored
    .setOutputPath('public/build/')

    .copyFiles({
        from: './assets/images'
    })


    // public path used by the web server to access the output path
    .setPublicPath('/build')
    // only needed for CDN's or sub-directory deploy
    //.setManifestKeyPrefix('build/')

    /*
     * ENTRY CONFIG
     *
     * Add 1 entry for each "page" of your app
     * (including one that's included on every page - e.g. "app")
     *
     * Each entry will result in one JavaScript file (e.g. app.js)
     * and one CSS file (e.g. app.fontawesome) if your JavaScript imports CSS.
     */
    .addEntry('app', './assets/js/app.js')
    .addEntry('main', './assets/js/main.js')
    //.addEntry('page2', './assets/js/page2.js')

    // When enabled, Webpack "splits" your files into smaller pieces for greater optimization.
    .splitEntryChunks()

    // will require an extra script tag for runtime.js
    // but, you probably want this, unless you're building a single-page app
    .enableSingleRuntimeChunk()

     */
    .cleanupOutputBeforeBuild()
    .enableBuildNotifications()
    .enableSourceMaps(!Encore.isProduction())
    // enables hashed filenames (e.g. app.abc123.css)
    .enableVersioning(Encore.isProduction())

    // enables @babel/preset-env polyfills
    .configureBabel(() => {}, {
        useBuiltIns: 'usage',
        corejs: 3
    })

    // enables Sass/SCSS support
    .enableSassLoader()

    // uncomment if you use TypeScript
    //.enableTypeScriptLoader()

    // uncomment to get integrity="..." attributes on your script & link tags
    // requires WebpackEncoreBundle 1.4 or higher
    .enableIntegrityHashes(Encore.isProduction())

    // uncomment if you're having problems with a jQuery plugin
    .autoProvidejQuery({
        $: 'jquery',
        jQuery: 'jquery',
        'window.jQuery': 'jquery'
    })

    // uncomment if you use API Platform Admin (composer req api-admin)
    //.enableReactPreset()
    //.addEntry('admin', './assets/js/admin.js')
;

module.exports = Encore.getWebpackConfig();

```


I got nothing.

在webpack.config.js中，尝试使用：

man xhost

取消评论（如果您有评论）

.autoProvidejQuery()

并删除

.enableSingleRuntimeChunk()

在app.js中注释.autoProvidejQuery({ $: 'jquery', jQuery: 'jquery', 'window.jQuery': 'jquery' })并使用jquery

在base.html.twig中使用

//const $ = require('jquery');

最终运行{% block javascripts %} {{ encore_entry_script_tags('app') }} {% endblock %}（对于dev env）或yarn encore dev（对于prod env）并重新加载页面

我将jQuery添加到我的网站时，我的JS不起作用
