javascript - Webpack 和 babel-loader - corejs2 中的定义属性错误

Question

您好，使用 webpack 和 babel-loader 编译我的 js 时出现以下错误

*

../vendor/xxx/xxx/assets/js/xxx.js 中的错误找不到模块：错误：无法解析 xxx 中的“@babel/runtime-corejs2/core-js/object/define-property”

*

这是我的 webpack.config.js 的重要部分

module: {
    rules: [
        {
            test: /\.js$/,
            exclude: /(node_modules)/,
            use: {
                loader: 'babel-loader',
                query: {
                    presets: ['@babel/preset-env'],
                    plugins: [
                        ['@babel/plugin-transform-runtime', {
                            'corejs': 2,
                            'helpers': false,
                            'regenerator': false,
                            'useESModules': false,
                        }]
                    ],
                    cacheDirectory: 'node_modules/.cache/babel-loader'
                }
            }
        },

    ]
},

这是我的 package.json
