【问题描述】:

我正在运行 gulp 和 webpack 以解析 bootstrap 4 中的 modal.js 文件,但是,我收到以下错误:

> gulp scripts
...
ERROR in ./wp-content/themes/rehub-blankchild/js/modules/Modal.js
Module build failed: SyntaxError: C:\Users\admin\Desktop\project\wp-content\themes\rehub-blankchild\js\modules\Modal.js: This experimental syntax requires enabling the parser plugin: 'objectRestSpread' (223:8)

 @ ./wp-content/themes/rehub-blankchild/js/scripts.js 7:36-62
[15:32:06] Finished 'scripts' after 1.86 s

我的 webpack 配置如下所示:

const path = require('path'),
settings = require('./settings');

module.exports = {
  entry: {
    App: settings.themeLocation + "js/scripts.js"
  },
  output: {
    path: path.resolve(__dirname, settings.themeLocation + "js"),
    filename: "scripts-bundled.js"
  },
  module: {
    rules: [
      {
        test: /\.js$/,
        exclude: /node_modules/,
        use: {
          loader: 'babel-loader',
          options: {
            presets: ['@babel/preset-env'],
          }
        }
      }
    ]
  }
}

我的 gulp 任务gulp scripts 基本上启动了 webpack:

gulp.task('scripts', function(callback) {
  webpack(require('./webpack.config.js'), function(err, stats) {
    if (err) {
      console.log(err.toString());
    }

    console.log(stats.toString());
    callback();
  });
}); 

我已经为 babel 安装了plugin-syntax-object-rest-spread。请参阅下面的 package.json 了解我的依赖项:

“开发依赖”:{ "@babel/core": "7.0.0-beta.34", "@babel/plugin-syntax-object-rest-spread": "^7.0.0-beta.44", "@babel/preset-env": "7.0.0-beta.34", “自动前缀”:“7.2.2”, "babel-loader": "8.0.0-beta.0", “浏览器同步”:“2.18.13”, “吞咽”:“3.9.1”, "gulp-postcss": "7.0.0", "postcss-color-function": "4.0.1", “postcss-hexrgba”:“1.0.0”, “postcss-import”:“11.0.0”, “postcss-mixins”:“6.2.0”, “postcss嵌套”:“3.0.0”, “postcss-simple-vars”:“4.1.0”, “网络包”:“3.10.0” }, “依赖”:{ “jQuery”:“3.2.1”, “normalize.css”:“7.0.0”, “光滑轮播”:“1.8.1” }

任何建议我做错了什么以及为什么会出现上述错误?

感谢您的回复!

【问题讨论】:

  • 你需要将插件添加到你的 .babelrc (或者无论 webpack 这样做,看起来像是 babel-loader 的 options 的一部分),以便 babel 知道去寻找它太
  • @PaulS。感谢你的回复!任何建议如何将插件添加到 webpack?我没有在我的构建设置中使用.babelrc

【解决方案1】:

刚刚通过修改 webpack 修复了错误。见下文如何修改规则部分:

  rules: [
    {
      test: /\.js$/,
      exclude: /(node_modules|bower_components)/,
      use: {
        loader: 'babel-loader',
        options: {
          presets: ['@babel/preset-env'],
          plugins: [require('@babel/plugin-proposal-object-rest-spread')]
        }
      }
    }
  ]
