Question

我正在使用带有webstorm的babeljs。巴贝尔的论点是：

- source-maps --out-file $ FileNameWithoutExtension $ -compiled.js $ FilePath $

我有以下es6代码：

export function primeFactors(num) {

    let res = [];
    let n = 2;
    while (num > 1) {
        while(num%n ===0) {
            res.push(n);
        }
        n++;

    }
    return res;
}

它被转换为

"use strict";

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

function primeFactors(num) {

    var res = [];
    var n = 2;
    while (num > 1) {
        while (num % n === 0) {
            res.push(n);
        }
        n++;
    }
    return res;
}

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

我有一个需要文件的脚本

import {primeFactors} from "lib/numUtils";

它被转化为

"use strict";

var _libNumUtils = require("lib/numUtils");

//# sourceMappingURL=ex3-compiled.js.map

当我使用nodejs运行脚本时，我得到了

export function primeFactors(num) {
^^^^^^

     at Object.Module._extensions..js (module.js:478:10)

可能是什么原因？
