我正在尝试使用 grunt-babel 将我的 es6 编译为 es5。当我在命令行中输入 grunt babel 时，它挂起并且从不运行 babel。它不会返回错误或崩溃只是挂起。我的 Gruntfile.js 中还有其他任务，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:

}
}.babelrc 看起来像这样:
{
"presets": ["es2015"]
}从昨天开始我就一直在尝试解决这个问题，但是没有错误消息就很难知道问题出在哪里。我将 babel 用作字符串，但我也尝试过不使用引号，但效果完全相同。我还尝试将 presets: ['babel-preset-es2015'] 添加到 'babel' 下的选项，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查看其他文件，请告诉我。在此先感谢您的所有帮助!
最佳答案
找到了!删除行
grunt.registerTask('babel', ['babel']);
它会导致无限循环。您已经有一个名为 babel 的任务，因此该行只是用无限任务重新定义了它。
此外，您可能希望 'js/survey.js': 'build/survey.js' 为 'build/survey.js': 'js/survey.js'。格式为target: source
