grunt-babel挂起并且不会返回错误消息

Question

我试图用grunt-babel将我的es6编译成es5.当我进入grunt babel命令行时,它会挂起并且永远不会运行babel.它不会返回错误或崩溃它只是挂起.我在Gruntfile.js中有其他任务,它们运行得很好,因此Gruntfile.js的结构是正确的.

这是我的Gruntfile:

'use strict';

module.exports = function(grunt) {
  require('load-grunt-tasks')(grunt);

  // initialize Grunt
  grunt.initConfig({
    pkg: grunt.file.readJSON('package.json'),

    'babel': {
      options: {
        sourceMap: true,
        presets: ['babel-preset-es2015']
      },
      dist: {
        files: {
          'js/survey.js': 'build/survey.js'
        }
      }
    },
    // create jshint task
    jshint: {
      dev: {
        // tell jshint what check
        src: ['Gruntfile.js', 'server.js', 'js/**/*.js', 'models/**/*.js', 'routes/**/*.js', '!build/**', '!tests/client/bundle.js', '!tests/karma_tests/bundle.js', '!js/imageMapResizer.min.js', '!js/kickstart.js', '!js/form-validator.js', '!js/imageMapResizer.js', '!js/jquery-ui.min.js', '!js/jquery.base64.js', '!js/kickstart.js'],
        options: {
          node: true,
          globals: {
            describe: true,
            it: true,
            before: true,
            after: true,
            beforeEach: true,
            afterEach: true,
            res: true
          }
        }
      },

      mocha: {
        // tell mocha where test files are
        src: ['tests/test_entry.js', '!tests/client/bundle.js', '!tests/karma_tests/bundle.js'],
        options: {
          node: true,
          globals: {
            describe: true,
            it: true,
            before: true,
            after: true,
            beforeEach: true,
            afterEach: true,
            res: true,
            expect: true
          }
        }
      },
      jasmine: {
        src: ['<%= jshint.dev.src %>', '<%= jshint.mocha.src %>'],
        options: {
          node: true,
          jasmine: true,
          globals: {
            describe: true,
            it: true,
            before: true,
            after: true,
            beforeEach: true,
            afterEach: true,
            expect: true,
            react: true
          }
        }
      },

      // create jscs task
      jscs: {
        dev: {
          // tell jscs to test the same files as jshint
          src: ['<%= jshint.dev.src %>', '<%= jshint.mocha.src %>']
        }
      }
    },

    mocha: {
      // tell mocha where the test file is
      src: ['tests/test_entry.js'],
      options: {
        node: true,
        globals: {
          describe: true,
          it: true,
          before: true,
          after: true,
          beforeEach: true,
          afterEach: true,
          res: true,
          expect: true
        }
      }
    },

    // create simplemocha task
    simplemocha: {
      dev: {
        src: ['tests/test_entry.js']
      }
    }
  });

  // register linting task
  grunt.registerTask('lint', ['jshint:dev', 'jshint:mocha', 'jshint:jasmine']);
  // register mocha test task
  grunt.registerTask('test', ['simplemocha:dev']);
  grunt.registerTask('babel', ['babel']);
  grunt.registerTask('default', ['test']);
};

这是我的package.json:

{
  "name": "event_site_bootstrap",
  "version": "0.1.0",
  "description": "",
  "main": "server.js",
  "scripts": {
    "test": "mocha tests/test_entry.js",
    "start": "node server.js"
  },

  "dependencies": {

  },
  "devDependencies": {
    "babel-cli": "^6.7.5",

    "babylon": "^6.7.0",
    "chai": "^3.2.0",
    "chai-http": "^1.0.0",
    "cli-color": "^1.1.0",

    "grunt-simple-mocha": "^0.4.0",
    "load-grunt-tasks": "^3.5.0",
    "mocha": "^2.3.4"
  }
}

而.babelrc看起来像这样:

{
  "presets": ["es2015"]
}

我从昨天开始就试图解决这个问题,但没有错误信息,很难知道问题是什么.我使用babel作为字符串,但我也试过没有引号,它的行为完全一样.我也试过添加下面presets: ['babel-preset-es2015']的选项,'babel'但它没有改变任何东西.

任何帮助将不胜感激,如果您需要更多信息或想要查看其他文件,请告诉我.在此先感谢您的帮助!

找到了!删除该行

grunt.registerTask('babel', ['babel']);

它会导致无限循环.您已经有一个名为的任务babel,因此该行只是使用无限任务重新定义它.

你也可能想'js/survey.js': 'build/survey.js'成为'build/survey.js': 'js/survey.js'.格式是target: source
