Question

我无法进行汇总将我的ES6代码转换为ES5。它仍然在留言Warning: Error transforming main.js with 'babel' plugin: It looks like your Babel configuration specifies a module transformer. Please disable it. If you're using the "es2015" preset, consider using "es2015-rollup" instead. See https://github.com/rollup/rollup-plugin-babel#configuring-babel for more information Use --force to continue.

我的.babelrc

{
  "presets": [
    [
      "es2015-rollup",
      {
        "modules": false
      }
    ]
  ],
  "plugins": ["external-helpers"]
}

我的.gruntfile

"use strict";
var babel = require('rollup-plugin-babel');

module.exports = function( grunt ) {

  grunt.initConfig({

    //...

    rollup: {
      options: {
        plugins: function () {
          return [
            babel({
              babelrc: false,
              presets: ["es2015-rollup"]
            })
          ];
        },
      },
      main: {
        'dest': 'build/js/bundle.js',
        'src' : 'src/js/main.js',
      },
    },

  //...

  });

  // Load the tasks
  grunt.loadNpmTasks('grunt-contrib-watch');
  grunt.loadNpmTasks('grunt-contrib-sass');
  grunt.loadNpmTasks('grunt-contrib-uglify');
  grunt.loadNpmTasks('grunt-notify');
  grunt.loadNpmTasks('grunt-postcss');
  grunt.loadNpmTasks('grunt-rollup');

  grunt.registerTask( 'default', [ 'rollup', 'watch' ] );
  //...
};

我的devDependencies

  "devDependencies": {
    "autoprefixer": "^6.2.3",
    "babel-plugin-external-helpers": "^6.8.0",
    "babel-preset-es2015": "^6.16.0",
    "babel-preset-es2015-rollup": "^1.2.0",
    "grunt": "^0.4.5",
    "grunt-babel": "^6.0.0",
    "grunt-contrib-sass": "^0.9.2",
    "grunt-contrib-uglify": "^0.11.0",
    "grunt-contrib-watch": "^0.6.1",
    "grunt-notify": "^0.4.3",
    "grunt-postcss": "^0.7.1",
    "grunt-rollup": "^0.8.0",
    "rollup-plugin-babel": "^2.6.1"
  }

正如您所看到的，我使用了es2015-rollup预设，而不是es2015作为警告提示。另一件事是，如果我删除预设，我的代码根本没有被发现。

Answer 1

plugins选项应该是一个数组，而不是一个函数。

另外，在.babelrc中，您应该使用es2015而不是es2015-rollup，因为汇总版本仅为es2015插件{。}}。

Answer 2

如果你设置babelrc：false，你的配置将不会读取 .babelrc 配置文件。

忽略您的 .babelrc 文件，并在 Gruntfile.js 中的babel插件配置中尝试此操作：

 babel({
    babelrc: false,
    presets: [["es2015",{modules:false}]],
    exclude: ['./node_modules/**/*'], //make sure to point to your folder path
    plugins: ["external-helpers"]
 })

Grunt +汇总+ babel配置问题
