Webstorm意外令牌导出

我在Webstorm中遇到“意外的令牌导出”问题,其他StackOverflow帖子尚未解决。基本上我正在尝试使用下面的package.json和bar.js代码导入/导出模块功能。我正在使用Node.js 5x,Babel 6,我有一个File Watcher设置来动态进行Babel转换。

代码应该说明一切,我很感激有关如何解决它的任何想法。我再次尝试了其他StackOverflow建议,但此时没有运气。

//bar.js

'use strict';

export class Bar{
    constructor(){
        this.tempish = 'allo';
    }
}

//bar-compiled.js

'use strict';

Object.defineProperty(exports, "__esModule", {
    value: true
});

function _classCallCheck(instance, Constructor) { if (!(instance instanceof Constructor)) { throw new TypeError("Cannot call a class as a function"); } }

var Bar = exports.Bar = function Bar() {
    _classCallCheck(this, Bar);

    this.tempish = 'allo';
};

//# sourceMappingURL=bar-compiled.js.map

//index.js

'use strict';

import {Bar} from './bar'

console.log('This is a test.');

//index-compiled.js

'use strict';

var _bar = require('./bar');

console.log('This is a test.');

//# sourceMappingURL=index-compiled.js.map

//package.json

使用退出代码1完成处理

您的index-compiled.js代码是什么样的?似乎它需要原始bar.js而不是bar-compiled.js。 Node.js本身不能执行ES6代码,因此也就是错误。

我建议配置编译器将已转换的代码输出到一个单独的目录中,以避免使用&#39;编译的&#39;后缀。有关使用WebStorm设置Babel 6的说明,请参阅以下链接:http://mcculloughwebservices.com/2015/12/10/webstorm-babel-6-plugin/
