rails 6 jquery not working in production 错误说 $ 没有定义

Question

我收到错误 $ is not defined only in production 错误不会发生在开发中，$ 是在 config/webpack/environment.js 中定义的

    const { environment } = require('@rails/webpacker')
    // const customConfig = require('./custom');
    const webpack = require('webpack')

    environment.plugins.prepend('Provide',
        new webpack.ProvidePlugin({
         $: "jquery",
        jQuery: "jquery",
        Popper: ['popper.js', 'default']
    }),)

    const aliasConfig = {
    'jquery': 'jquery-ui-dist/external/jquery/jquery.js',
    'jquery-ui': 'jquery-ui-dist/jquery-ui.js'
    };

    environment.config.set('resolve.alias', aliasConfig);

    module.exports = environment

尝试添加到您的app/javascript/packs/application.js：

global.$ = require("jquery")
